• Five hours of Task Flow Overview Recordings Available

  - by Frank Nimphius

  In addition to the ADF Controller task flow documentation in Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework 11g Release 1 http://download.oracle.com/docs/cd/E21764_01/web.1111/b31974/partpage3.htm#BABHIIAI The ADF Insider website … http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfinsider-093342.html … hosts five online videos that explain how to build and work with ADF Controller task flows in Oracle ADF. ADF Task Flow - Overview (Part 1) This 90 minute recording introduces the concept of ADF unbounded and bounded task flows, as well as other ADF Controller features. The session starts with an overview of unbounded task flows, bounded task flows and the different activities that exist for developers to build complex application flows. Exception handling and the Train navigation model is also covered in this first part of a two part series. By example of developing a sample application, the recording guides viewers through building unbounded and bounded task flows. This session is continued in a second part. http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/taskflow-overview-p1/taskflow-overview-p1.html ADF Task Flow - Overview (Part 2) This 75 minute session continues where part 1 ended and completes the sample application that guides viewers through different aspects of unbounded and bounded task flow development. In this recording, memory scopes, save for later, task flow opening in dialogs and remote task flow calls are explained and demonstrated. If you are new to ADF Task Flow, then it is recommended to first watch part 1 of this series to be able to follow the explanation guided by the sample application. http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/taskflow-overview-p2/taskflow-overview-p2.html ADF Region Interaction - An Overview This session covers most of the options that exist for communicating between regions. It briefly discusses what it takes to build regions from bounded task flows before going into details using slides and samples. The following interaction is explained: contextual events, queue action in region, input parameters and PPR, drag and drop, shared Data Controls, parent action and region navigation listener. http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/adf-region-interaction/adf-region-interaction.html ADF Region Interaction - Contextual Events Contextual event is used as a communication channel between a parent view and its contained regions, as well as between regions. By example, this session explains how to set up contextual events, how to define producers and event listeners and how to define the payload message. http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/AdfInsiderContextualEvents/AdfInsiderContextualEvents.html

• Google analytics - drop in traffic

  - by Andy

  Bit of a general question here. We are in the process of converting a number of our clients from older web sites to new ones. The problem we are getting, and sorry for being so general here, is we are getting a sharp decline in traffic as reported on Google Analytics. It's not a gradual decline, it seems to hit almost as soon as the new site goes live. I've just got a few questions to see if there is something we are doing wrong: a) We are using the same analytics accounts going from old to new site. Is this a bad idea? b) The actual analytics code is integrated into the pages using a server-side include. IS this a bad idea? c) We structure our sites differently to our old site. IE. The old sites would pretty must have all the web pages in the root directory, and hyperlinks would be linked to the page files: EG. <a href="somepage.aspx">Link</a> Our new sites now have a directory structure that pretty much reflects the navigation structure, and hyper links link to the pages directory instead of the actual page: EG. <a href="/new-items/shoes/">New shoes</a> Is this a bad idea. I'm really searching for a needle in a haystack here. Would appriciate any help or advice as to why we are getting such a sharp and sudden drop in traffic. Again, so this is such a general question. Thanks in advance.

• Programmatically disclosing a node in af:tree and af:treeTable

  - by Frank Nimphius

  A common developer requirement when working with af:tree or af:treeTable components is to programmatically disclose (expand) a specific node in the tree. If the node to disclose is not a top level node, like a location in a LocationsView -> DepartmentsView -> EmployeesView hierarchy, you need to also disclose the node's parent node hierarchy for application users to see the fully expanded tree node structure. Working on ADF Code Corner sample #101, I wrote the following code lines that show a generic option for disclosing a tree node starting from a handle to the node to disclose. The use case in ADF Coder Corner sample #101 is a drag and drop operation from a table component to a tree to relocate employees to a new department. The tree node that receives the drop is a department node contained in a location. In theory the location could be part of a country and so on to indicate the depth the tree may have. Based on this structure, the code below provides a generic solution to parse the current node parent nodes and its child nodes. The drop event provided a rowKey for the tree node that received the drop. Like in af:table, the tree row key is not of type oracle.jbo.domain.Key but an implementation of java.util.List that contains the row keys. The JUCtrlHierBinding class in the ADF Binding layer that represents the ADF tree binding at runtime provides a method named findNodeByKeyPath that allows you to get a handle to the JUCtrlHierNodeBinding instance that represents a tree node in the binding layer. CollectionModel model = (CollectionModel) your_af_tree_reference.getValue(); JUCtrlHierBinding treeBinding = (JUCtrlHierBinding ) model.getWrappedData(); JUCtrlHierNodeBinding treeDropNode = treeBinding.findNodeByKeyPath(dropRowKey); To disclose the tree node, you need to create a RowKeySet, which you do using the RowKeySetImpl class. Because the RowKeySet replaces any existing row key set in the tree, all other nodes are automatically closed. RowKeySetImpl rksImpl = new RowKeySetImpl(); //the first key to add is the node that received the drop //operation (departments).            rksImpl.add(dropRowKey);    Similar, from the tree binding, the root node can be obtained. The root node is the end of all parent node iteration and therefore important. JUCtrlHierNodeBinding rootNode = treeBinding.getRootNodeBinding(); The following code obtains a reference to the hierarchy of parent nodes until the root node is found. JUCtrlHierNodeBinding dropNodeParent = treeDropNode.getParent(); //walk up the tree to expand all parent nodes while(dropNodeParent != null && dropNodeParent != rootNode){    //add the node's keyPath (remember its a List) to the row key set    rksImpl.add(dropNodeParent.getKeyPath());      dropNodeParent = dropNodeParent.getParent(); } Next, you disclose the drop node immediate child nodes as otherwise all you see is the department node. Its not quite exactly "dinner for one", but the procedure is very similar to the one handling the parent node keys ArrayList<JUCtrlHierNodeBinding> childList = (ArrayList<JUCtrlHierNodeBinding>) treeDropNode.getChildren();                     for(JUCtrlHierNodeBinding nb : childList){   rksImpl.add(nb.getKeyPath()); } Next, the row key set is defined as the disclosed row keys on the tree so when you refresh (PPR) the tree, the new disclosed state shows tree.setDisclosedRowKeys(rksImpl); AdfFacesContext.getCurrentInstance().addPartialTarget(tree.getParent()); The refresh in my use case is on the tree parent component (a layout container), which usually shows the best effect for refreshing the tree component.

• Creating ADF Faces Comamnd Button at Runtime

While creating the button is not difficult at all, adding behavior to it requires knowing about how to dynamically create and add an action listener reference. The example code below shows two methods: The first method, handleButtonPress is a public method exposed on a managed bean. public void handleButtonPress(ActionEvent event){   System.out.println("Event handled");   //optional: partially refresh changed components if command   //issued as a partial submit } The second method is called in response to a user interaction or on page load and dynamically creates and adds a command button. When the button is pressed, the managed bean method – the action handler – defined above is called. The action handler is referenced using EL in the created MethodExpression instance. If the managed bean is in viewScope, backingBeanScope or pageFlowsScope, then you need to add these scopes as a prefix to the EL (as you would when configuring the managed bean reference at design time) //Create command button and add it as a child to the parent component that is passed as an //argument to this method private void reateCommandButton(UIComponent parent){   RichCommandButton edit = new RichCommandButton();   //make the request partial   edit.setPartialSubmit(true);   edit.setText("Edit");                             //compose the method expression to invoke the event handler   FacesContext fctx = FacesContext.getCurrentInstance();   Application application = fctx.getApplication();   ExpressionFactory elFactory = application.getExpressionFactory();   ELContext elContext = facesCtx.getELContext();   MethodExpression methodExpressio = null;   //Make sure the EL expression references a valid managed bean method. Ensure   //the bean scope is properly addressed    methodExpression =  elFactory.createMethodExpression(                              elContext,"#{myRequestScopeBean.handleButtonPress}",                             Object.class,new Class[] {ActionEvent.class});   //Create the command buttonaction listener reference   MethodExpressionActionListener al = null;          al= new MethodExpressionActionListener(methodExpression);    edit.addActionListener(al);     //add new command button to parent component and PPR the component for     //the button to show    parent.getChildren().add(edit);    AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();     adfFacesContext.addPartialTarget(parent);  }

• Gotcha when using JavaScript in ADF Regions

  - by Frank Nimphius

  You use the ADF Faces af:resource tag to add or reference JavaScript on a page. However, adding the af:resource tag to a page fragment my not produce the desired result if the script is added as shown below <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> Adding scripts to a page fragment like this will see the script added for the first page fragment loaded by an ADF region but not for any subsequent fragment navigated to within the context of task flow navigation. The cause of this problem is caching as the af:resource tag is a JSP element and not a lazy loaded JSF component, which makes it a candidate for caching. To solve the problem, move the af:resource tag into a container component like af:panelFormLayout so the script is added when the component is instantiated and added to the page.  <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:panelFormLayout> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> </af:panelFormLayout> Magically this then works and prevents browser caching of the script when using page fragments.

• Historical origins of Scala implicits

  - by Frank

  Scala has been called complex with its rich feature set by many of my colleagues and some even blamed all those new features of it. While most programmers are aware of the OO-features, and at least the decent ones also know about functional programming, there is one feature in particular in Scala for which I am not aware of its historical origins. Given that a major mantra of our profession is to not reinvent the wheel, I am rather confident, that Scala does not have any actual unheard-of-before features, but I stand to be corrected on this one if necessary. To get to the actual question, while I am aware of the origins of most of Scala's features I have never seen something like its implicit declarations before. Are there other (older!) languages out there which also provide this feature? Does it make sense to distinguish the different cases of implicits (as they may originate from different sources), namely implict conversions and implicit parameters?

• Remote Task Flow vs. WSRP Portlets

The remote task flow is accessed either from a direct browser GET request or, when called from another ADF application, through the task flow call activity. For more information about how to invoke remote task flows from a task flow call activity see chapter 15.6.4 How to Call a Bounded Task Flow Using a URL of the Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework at http://docs.oracle.com/cd/E23943_01/web.1111/b31974/taskflows_activities.htm#CHDJDJEF Compared to WRSP portlets, remote task flows in Oracle JDeveloper 11g R1 and R2 have a functional limitation in that they cannot be embedded as a region on a page but require the calling ADF application to navigate off to another application and page. The difference between a remote task flow call using the task flow call activity and a simple redirect to a remote Java EE application is that the remote task flow has a state token attached that allows to restore the state of the calling application upon task flow return. A use case for a remote task flow call activity is a "yellow page lookup" scenario in which different ADF applications use an remote task flow to lookup people, products or similar to return a selected value to the calling application. Note that remote task flow calls need to be performed from a bounded or unbounded top level task flow of the calling application. If called from a region (using the parent call activity) in a page, the region state is not recovered upon task flow return. ADF developers recently have identified remote task flows as an architecture pattern to partition their ADF applications into independently deployed Java EE applications. While this sounds like a desirable use of the remote task flow feature, it is not possible to achieve for as long as remote task flows don't render as an ADF region.

• Access secondary hard disk from Virtual Machine

  - by Frank V

  I have a fairly specific question. I had Ubuntu on my Laptop (for years). For a variety of reasons, I've had to switch to Windows but the computer has two hard drives. The main drive was reformatted and I've installed windows. The second hard drive still has the Linux system disk format (not sure on type). Obviously, windows can't access it but can I access it from a Virtual machine (VirtualBox) or will I need to load up a Live-Session to access / move the contents? Edit: If this is possible, how would one proceed to mount the disk?

• Assign subdomains to separate ports on web server

  - by Michael Frank

  I have set up an Abyss web server as a little experiment, and I want to know if it is possible to assign subdomains to different ports on the machine the web server is running on. I have a couple webUIs that I'd like to assign subdomains: 192.168.1.1:8000 becomes example.com/webui1/ 192.168.1.1:8001 becomes example.com/webui2/ The webUIs are available by accessing their ports via example.com:8000. I have tried using a reverse proxy, but it seems that this is only usable on one internal IP at a time. What other options do I have? Answer is good, but my current set up doesn't meet the requirements. Abyss Web Server X2 is required to use Virtual Hosts with Abyss.

• Cannot logon to POP server on my VPS or recieve emails

  - by Andy

  I recently purchased an unmanaged VPS to host my business websites, however I am struggling to get the email accounts working as I have only ever had experience with shared hosting. The VPS is running CentOS and I have Webmin/Virtualmin installed. I have added my domain, which is lyke.org.uk, and that is working OK. However, when I've added a user and tried to access their email account using Apple Mail, I've been able to establish a SMTP connection but I've not been able to login using POP. Furthermore, I've set up squirrelmail and I can send an email to any email address from there but I haven't recieved any that I have sent to that email address from other accounts. I would very much appreciate any help or suggestions as I am completely new to VPS and web hosting without Plesk or cPanel.

• gnome-control-center can't set display resolution under openbox

  - by Andy

  I'm running Ubuntu 11.10 with Openbox on my laptop. Since I need to plug different external displays into it and Openbox environment doesn't automatically pick them up, I thought the best solution I can come up with is to use gnome-control-center and it's display settings tool from within Openbox. But although this tool does detect monitors correctly, it can't do any change -- clicking Apply button just doesn't seem to do anything. So my questions are: 1) how to get this tool working? 2) how to run "Displays" tool directly from command-line, skipping control center? 3) is there a better way to automatically detect and set resolutions on internal/external monitors under Openbox? Please note I tried arandr too and it doesn't even work for my environment (doesn't detect external display plugging in at all). For what it's worth, my laptop is Lenovo G560, Ubuntu is x64 version with all the updates rolled over. Thanks for your consideration.

• How can I assign custom icons to folders?

  - by Frank Souza

  How do I assign custom icons to folders, as well as the default folders Desktop, Downloads, Music, etc.? I know that one way is to assign the properties of folders, but I want to assign icons in the same way that are assigned the default folders, so the custom icons will also appear in the Nautilus bookmarks. I've also seen this question custom icon in "Places" menu <<, but that is not what I seek. UPDATE My main intention is this: I want the markers to display custom icons like the dolphin. I know it's possible, because the folder "Desktop", "Documents", "Music" has its own custom icons in bookmarks. How?

• How-to populate different select list content per table row

To implement this use case, the select list of the table column is populated dynamically from a managed bean for each row. The table's current rendered row object is accessible in the managed bean using the #{row} expression, where "row" is the value added to the table's var property. <af:table var="row">   ...   <af:column ...>     <af:selectOneChoice ...>         <f:selectItems value="#{browseBean.items}"/>     </af:selectOneChoice>   </af:column </af:table> The browseBean managed bean referenced in the code snippet above has a setItems and getItems method defined that is accessible from EL using the #{browseBean.items} expression. When the table renders, then the var property variable - the #{row} reference - is filled with the data object displayed in the current rendered table row. The managed bean getItems method returns a List<SelectItem>, which is the model format expected by the f:selectItems tag to populate the af:selectOneChoice list. public void setItems(ArrayList<SelectItem> items) {} //this method is executed for each table row public ArrayList<SelectItem> getItems() {   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory efactory =          fctx.getApplication().getExpressionFactory();          ValueExpression ve =          efactory.createValueExpression(elctx, "#{row}", Object.class);      Row rw = (Row) ve.getValue(elctx);         //use one of the row attributes to determine which list to query and   //show in the current af:selectOneChoice list  // ...  ArrayList<SelectItem> alsi = new ArrayList<SelectItem>();  for( ... ){      SelectItem item = new SelectItem();        item.setLabel(...);        item.setValue(...);        alsi.add(item);   }   return alsi;} For better performance, the ADF Faces table stamps it data rows. Stamping means that the cell renderer component - af:selectOneChoice in this example - is instantiated once for the column and then repeatedly used to display the cell data for individual table rows. This however means that you cannot refresh a single select one choice component in a table to change its list values. Instead the whole table needs to be refreshed, rerunning the managed bean list query. Be aware that having individual list values per table row is an expensive operation that should be used only on small tables for Business Services with low latency data fetching (e.g. ADF Business Components and EJB) and with server side caching strategies for the queried data (e.g. storing queried list data in a managed bean in session scope).

Global managed beans contain helper - or utility - methods like or instead of JSFUtils and ADFUtils. The difference between global managed beans and static helper classes like JSFUtis and ADFUtils is that they are EL accessible, providing reusable functionality that is ready to use on UI components and - if accessed from Java - in other managed beans. For example, the ADF Faces page template (af:pageTemplate) allows you to define attributes for the consuming page to pass in object references or strings into it. It does not have method attributes that allow command components contained in a template to invoke listeners in managed beans and the ADF binding layer, or to execute actions. To create templates that provide global button or menu functionality, like logon, logout, print etc., an option for developers is to deployed managed beans with the ADF Faces page templates. To deploy a managed bean with a page template, create an ADF library from the project containing the template definition and import this ADF library into the target project using the Resource palette. When importing an ADF library, all its content is added to the project, including page template definitions, managed bean sources and configurations. More about page templates http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_pageTemplate.html Another use-case for globally configured managed beans is for creating helper methods to be used in many applications. Instead of creating a base managed bean class that then is extended by all managed beans used in applications, you can deploy a managed bean in a JAR file and add the faces-config.xml file with the managed bean configuration to the JAR's META-INF folder as shown below. Using a globally configured managed bean allows you to use Expression Language in the UI to access common functionality but also use Java in application specific managed beans. Storing the faces-config.xml file in the JAR file META-INF directory automatically makes it available when the JAR file is found in the class path of an application.

• Partial Submit vs. Auto Submit

  - by Frank Nimphius

  Partial Submit ADF Faces adds the concept of partial form submit to JavaServer Faces 1.2 and beyond. A partial submit actually is a form submit that does not require a page refresh and only updates components in the view that are referenced from the command component PartialTriggers property. Another option for refreshing a component in response to a partial submit is call AdfContext.getCurrentInstance.addPartialTarget(component_instance_handle_goes_here)in a managed bean. If a form contains required fields that the user left empty invoking the partial submit, then errors are shown for each of the field as the full form gets submitted. Autosubmit An input component that has its autosubmit property set to true also performs a partial submit of the form. However, this time it doesn't submit the entire form but only the component that triggers the submit plus components referenced it in their PartialTriggers property. For example, consider a form that has three input fields inpA, inpB and inpC with autosubmit=true set on inpA and required=true set on inpB and inpC. use case 1: Running the view, entering data into inpA and then tabbing out of the field will submit the content for inpA but not for inpB and inpC. Further more, none of the required field settings on inpB and inpC causes an error. use case 2: You change the configuration of inpC and set its PartialTriggers property to point to the ID of component inpA. When rerunning the sample, entering a value into inpA and tabbing out of the field will now submit the inpA and inpC fields and thus show an error for the missing required value on inpC. Internally, using autosubmit=true on an input component sets the event root to just this field, which good to have in case of dependent field validation or behavior. The event root can extended to include other components by using the Partial Triggers property on these components to point to the input field that has autosubmit=true defined. PartialSubmit vs. AutoSubmit Partial submit set on a command component submits the whole form and leaves it to the developer to decide which UI component is refreshed in response. Client side required field validation (as well as the server side equivalent) is not disabled by executed in this scenario. Setting immediate=true on the command item to skip validation doesn't help as it would also skip the model update. Auto submit is a functionality on the input components and also performs a partial form submit. However, in addition an event root is defined that narrows the scope for the submitted data and thus the components that are validated on the request.

• Asynchronous update design/interaction patterns

  - by Andy Waite

  These days many apps support asynchronous updates. For example, if you're looking at a list of widgets and you delete one of them then rather than wait for the roundtrip to the server, the app can hide the one you deleted, giving immediate feedback. The actual deletion on the server will happen in the background. This can be seen in web apps, desktop apps, iOS apps, etc. But what about when the background operation fails. How should you feed back to the user? Should you restore the UI to the pre-deletion state? What about when multiple background operations fail together? Does this behaviour/pattern have a name? Perhaps something based on the Command pattern?

• My laptop with Linux/ Ubuntu isn't working

  - by Andy Campos

  I have a dell laptop with ubuntu linux. A day I tried to start it up and a black screen just appeared that says: GNU GRUB version1.98+20100804-5ubuntu3 (and these clickable options:) -Ubuntu, with Linux 2.6.35-22-generic -Ubuntu, with Linux 2.6.35-22-generic (recovery mode) -Memory test (memtest86+) -Memory test (memtest86+, serial console 115200) When I click the first one, a bunch of text appears like: mount: mounting /dev/disk/by-uuid/8396a225... failed: invalid argument mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /sys on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Target file system doesn't have requested /sbin/init No init found. Try passing init= bootarg Enter 'help' for a list of built-in commands BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) (initramfs) When I enter 'help' a bunch more incomprehensible text appears. Whenever I press the enter key all that pops up is (intetramfs) If anyone can make rhyme or reason out of this please, please help me out so it can boot up normally and i can be set. If there's some kind of special code I have to type in or something I know nothing about computers.

• Ubuntu One under KDE

  - by Andy Goss

  Currently, while Ubuntu One can be installed under KDE, Dolphin does not know about it, so it cannot set folders other than Ubuntu One to sync. There is a command line utility, "u1sdtool", which performs most if not all the functions you need. Setting the keyring password to be the same as your login won't prevent Ubuntu One asking you for it again on login. If you want to change it, install Seahorse, look for it in your menus as "Passwords and Keys", and right click over "Passwords: default", then select "Change Password". The various deleting tricks I've read about don't work for me. There is an ubuntuone-client-kde being developed, but no clue as to when it will appear in a stable repo. Any further advice will be welcomed by me and doubtless a few other KDE users.

• Windows 2008 R2, UDDI 3.0 and No Admin Links

  - by Andy Morrison

  Windows 2008 R2 might end up giving me a heart attack at some point. Yesterday I installed and configured UDDI 3.0 as part of an ESB 2.0 install & config.  After configuring UDDI 3.0, if I browsed to the localhost/uddi virtual directory from IIS, all of the links would show up in UDDI.  If opened up IE and went to the UDDI site only the Home and Search links would show up. You've probably already guessed at what the "fix" was... I had to Run IE as Administrator.  Then when I browse to the UDDI site all of the links show up.

• PanelCollection Confusion ... or, what is an event root ?

While this appears confusing it works as designed. Instead of a full page re-rendering, ADF Faces events and components can trigger partial page refresh, in which only portions of a page are refresh upon a request. In addition, some components - including the af:popup and af:subForm - represent event roots. Event roots don't propagated event notification outside of the component tag boundary, which means that the ADF Faces lifecycle only executed on components that are children of the event root component. The PanelCollection component is an event root and therefore only validates and refreshes data of its child components.

• Pretty URL in ADF Faces of JDeveloper 11.1.2.2

  - by Frank Nimphius

  Many features planned for Oracle JDeveloper 12c find their way into current releases of Oracle JDeveloper 11g R1 and JDeveloper 11g R2. One example of such a feature is "pretty URL" - or "clean URL" as the Oracle JDeveloper 11g R2 (11.1.2.2) documentation puts it. "A.2.3.24 Clean URLs Historically, ADF Faces has used URL parameters to hold information, such as window IDs and state. However, URL parameters can prevent search engines from recognizing when URLs are actually the same, and therefore interfere with analytics. URL parameters can also interfere with bookmarking. By default, ADF Faces removes URL parameters using the HTML5 History Management API. If that API is unavailable, then session cookies are used.You can also manually configure how URL parameters are removed using the context parameter oracle.adf.view.rich.prettyURL.OPTIONS. Set the parameter to off so that no parameters are removed. Set the parameter to useHistoryApi to only use the HTML5 History Management API. If a browser does not support this API, then no parameters will be removed. Set the parameter to useCookies to use session cookies to remove parameters. If the browser does not support cookies, then no parameters will be removed." See: http://docs.oracle.com/cd/E26098_01/web.1112/e16181/ap_config.htm#ADFUI12856 So basically, what this part in the documentation says is: In JDeveloper 11g R2 (11.1.2.2), Oracle ADF Faces automatically removes its internally used dynamic parameters from the URL You can influence the setting with the prettyURL.OPTIONS context option, which however is not recommended you to do because the default behavior is able to detect if the browser client supports HTML 5 History management or not. In the latter case it the uses a session cookie and if this doesn't work, falls back to the "old" URL parameter adding. The information that is not so explicit and clearly mentioned in the documentation is that this is only for ADF Faces parameters (such as _afrLoop, Adf-Window-Id, etc.), but not the ADF controller token (_adf.ctrl-state)! Removing the ADF controller token is an enhancement request that will be implemented in Oracle JDeveloper 12c

• JBox2D Polygon Collisions Acting Strange

  I have been playing around with JBox2D and Slick2D and made a little demo with a ground object, a box object, and two different polygons.
