  • JSF 2.0: java based custom component + html table + facelets = data model not updated

    - by mikic
    Hi, I'm having problems getting the data model of a HtmlDataTable to be correctly updated by JSF 2.0 and Facelets. I have created a custom Java-based component that extends HtmlDataTable and dynamically adds columns in the encodeBegin method. @Override public void encodeBegin(FacesContext context) throws IOException { if (this.findComponent("c0") == null) { for (int i = 0; i < 3; i++) { HtmlColumn myNewCol = new HtmlColumn(); myNewCol.setId("c" + i); HtmlInputText myNewText = new HtmlInputText(); myNewText.setId("t" + i); myNewText.setValue("#{row[" + i + "]}"); myNewCol.getChildren().add(myNewText); this.getChildren().add(myNewCol); } } super.encodeBegin(context); } My test page contains the following <h:form id="fromtb"> <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> </test:MatrixTest> <h:commandButton id="btn" value="Set" action="#{MyManagedBean.mergeInput}"/> </h:form> <h:outputText id="mergedInput" value="#{MyManagedBean.mergedInput}"/> My managed bean class contains the following @ManagedBean(name="MyManagedBean") @SessionScoped public class MyManagedBean { private List model = null; private String mergedInput = null; public MyManagedBean() { model = new ArrayList(); List myFirst = new ArrayList(); myFirst.add(""); myFirst.add(""); myFirst.add(""); model.add(myFirst); List mySecond = new ArrayList(); mySecond.add(""); mySecond.add(""); mySecond.add(""); model.add(mySecond); } public String mergeInput() { StringBuffer myMergedInput = new StringBuffer(); for (Object object : model) { myMergedInput.append(object); } setMergedInput(myMergedInput.toString()); return null; } public List getModel() { return model; } public void setModel(List model) { this.model = model; } public String getMergedInput() { return mergedInput; } public void setMergedInput(String mergedInput) { this.mergedInput = mergedInput; } When invoked, the page is correctly rendered with a table made of 3 columns (added at runtime) and 2 rows (as my data model has 2 rows). However when the user enter some data in the input fields and then click the submit button, the model is not correctly updated and therefore the mergeInput() method creates a sequence of empty strings which is rendered on the same page. I have added some logging to the decode() method of my custom component and I can see that the parameters entered by the user are being posted back with the request, however these parameters are not used to update the data model. If I update the encodeBegin() method of my custom component as follow @Override public void encodeBegin(FacesContext context) throws IOException { super.encodeBegin(context); } and I update the test page as follow <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> <h:column id="c0"><h:inputText id="t0" value="#{row[0]}"/></h:column> <h:column id="c1"><h:inputText id="t1" value="#{row[1]}"/></h:column> <h:column id="c2"><h:inputText id="t2" value="#{row[2]}"/></h:column> </test:MatrixTest> the page is correctly rendered and this time when the user enters data and submits the form, the underlying data model is correctly updated and the mergeInput() method creates a sequence of strings with the user data. Why does the test case with columns declared in the facelet page works correctly (ie the data model is correctly updated by JSF) where the same does not happen when the columns are created at runtime using the encodeBegin() method? Is there any method I need to invoke or interface I need to extend in order to ensure the data model is correctly updated? I am using this test case to address the issue that is appearing in a much more complex component, therefore I can't achieve the same functionality using a facelet composite component. Please note that this has been done using NetBeans 6.8, JRE 1.6.0u18, GlassFish 3.0. Thanks for your help.

  • Silverlight Html Placeholder now support OOB mode

    With the official Silverlight 4 release this week, one of the things we introduced in the Telerik Silverlight controls is the ability to use the Html Placeholder control in OOB in the same way you do when the control is hosted in the browser. The good news is that you don't need to do anything in order to enable this feature. It comes out of the box and if you have an app that is using the HtmlPlaceholder you just need to install it in OOB mode to see the same html that you are seeing when the application is hosted in the browser. When in OOB mode we are using internally the Microsoft WebBrowser control to render the Html - that's why this feature is SL4 specific and is not available in the SL3 binaries (which we still officially support).   Go play with it and if you have any questions ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How do I reference the value of a constructed environment variable in a loop?

    - by Rob Spieldenner
    What I'm trying to do is loop over environment variables. I have a number of installs that change and each install has 3 IPs to push files to and run scripts on, and I want to automate this as much as possible (so that I only have to modify a file that I'll source with the environment variables). The following is a simplified version that once I figure out I can solve my problem. So given in my.props: COUNT=2 A_0=foo B_0=bar A_1=fizz B_1=buzz I want to fill in the for loop in the following script #!/bin/bash . <path>/my.props for ((i=0; i < COUNT; i++)) do <script here> done So that I can get the values from the environment variables. Like the following(but that actually work): echo $A_$i $B_$i or A=A_$i B=B_$i echo $A $B returns foo bar then fizz buzz

  • Java generic return tpye

    - by Colby77
    Hi, I'd like to write a method that can accept a type param (or whatever the method can figure out the type from) and return a value of this type so I don't have to cast the return type. Here is a method: public Object doIt(Object param){ if(param instanceof String){ return "string"; }else if(param instanceof Integer){ return 1; }else{ return null; } } When I call this method, and pass in it a String, even if I know the return type will be a String I have to cast the return Object. This is similar to the int param. How shall I write this method to accept a type param, and return this type?

  • jQuery selector depending on children

    - by wiradikusuma
    Hi guys, I have an HTML form consisting of some text-inputs. I'm using jqTransform to prettify them. Now I want to add two buttons that will add and remove text-input dynamically. Adding is easy: $('#container').append(''); $('input[name=foo]:last-child').jqTransInputText(); But removing is tricky: $('WHAT-TO-SELECT').remove(); I can't do "input[name=foo]:last-child" since it's already wrapped (some divs) by jqTransform. To put this question in another way: How do I select based on "who has child of type input with 'foo' as its name"?

  • how much concurrent http request can erlang handle

    - by user209123
    I am developing a application for benchmarking purposes, for which I require to create large number of http connection in a short time, I created a program in java to test how much threads is java able to create, it turns out in my 2GB single core machine, the limit is variable between 5000 and 6000 with 1 GB of memory given to JVM after which it hits outofmemoryerror with heap limit reached. It is suggested around that erlang will be able to generate much more concurrent processes, I am willing to learn erlang if it is capable of solving the problem , although I am interested in knowing can erlang be able to say generate somewhere around 100000 processes which are essentially http requests waiting for responses, in a matter of few seconds without reaching any limit like memory error etc.,

  • Getting all new messages from a Maildir in python

    - by Jesper
    I have a mail dir: foo@foo:~/Maildir$ ls -l total 288 drwx------ 2 foo foo 155648 2010-04-19 15:19 cur -rw------- 1 foo foo 440 2010-03-20 08:50 dovecot.index.log -rw------- 1 foo foo 112 2010-03-20 08:49 dovecot-uidlist -rw------- 1 foo foo 8 2010-03-20 08:49 dovecot-uidvalidity -rw------- 1 foo foo 0 2010-03-20 08:49 dovecot-uidvalidity.4ba48c0e drwx------ 2 foo foo 114688 2010-04-19 16:07 new drwx------ 2 foo foo 4096 2010-04-19 16:07 tmp And in python I'm trying to get all new messages (Python 2.6.5rc2).

  • Fixing permissions after FTPing ASP.NET code to a Linux system

    - by dnord
    First off, I'm running Mono to run ASP.NET on Linux, but that's not the question. It appears that, every time I clear out my application directory and upload, I have to go back in and fix the permissions. What I'm doing is chmod -R -c 755 /var/www/* ...and there are two questions. What's the deal with having to do this every time I FTP? Feels flaky. Is there a better permissions set than 755? Do I want different permissions for the /bin directory? Or can I fix this all with one fell swoop of chown?

  • Websphere 7 simple realm (like tomcat-users.xml)

    - by Heavy Bytes
    I am trying to port a J2EE app from Tomcat to Websphere and I'm not too familiar with Websphere. The only problem I am having is authorization (I use basic-authentication in my web.xml). In Tomcat I use the tomcat-users.xml file to define my users/passwords and to what roles they belong. How do I do this "simply" in Websphere? When deploying the EAR to Websphere it also asks me to map my role from web.xml to a user or group. Do I have to set up some sort of realm? Custom user registry? Thanks. UPDATE: I configured a Standalone custom registry, however I can't get a log-in prompt for username/password. It works just fine in Tomcat, and it doesn't in Websphere. Code from web.xml <security-constraint> <web-resource-collection> <web-resource-name>basic-auth security</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>HELLO_USER</role-name> </auth-constraint> <user-data-constraint>NONE</user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> <security-role> <role-name>HELLO_USER</role-name> </security-role>

  • ASP.Net & 960.gs Integrating the .css files into a new project.

    - by Baxter
    I've got a full layout designed using 960.gs and am wanting to use it in a ASP.net website but i'm getting warnings such as: "Warning File 'css/Reset.css' was not found." "Warning File 'css/Text.css' was not found." "Warning File 'css/960.css' was not found." "Warning File 'css/Base.css' was not found." I've tried adding a new similarly named folder to the solution explorer and 'add existing item' to add them in but it still seems to cause warnings and intelisense isn't recognising any of the 960.gs classes. Is there a recommended workflow for importing all of this in? I should add that it works perfectly well on the local development server and on the webspace, it's seemingly just VS that's complaining.

  • Multiple Servers with identical services

    - by Jerry Bailey
    I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

  • How to call a Biztalk net.TCP service from Raw TCP request?

    - by Burhan
    I have written a net.tcp based service in Biztalk 2006 R2 and it listens at a location, http://localhost:5060/WCFTcpService I need to call this service by using Raw TCP request. i.e. I don't want to create a proxy class and consume it in a .NET client application. How can I be able to do this? The real scenario is that an Oracle Stored procedure will be used to communicate with this service and the only way I am allowed to call this service is to send a TCP request to the Biztalk server that is hosting the service. Any help or tips would be really appreciated. Thanks.

  • Filtering code elements when analyzing source code.

    - by Martin
    Hi everybody, Currently I am making a survey about source code analysis and the thing that puzzles me greatly is what is it that project managers and developers would like to filter when analyzing source code (especially when applying OOP metrics - e.g. skpping insignificant methods and classes during analysis or filtering context-based elements according to the type of project). If you have any suggestions based on yout experience with code analysis I will greatly appreciate if you can share some ideas about filtering of elements. Thanks, Martin

  • JavaScript: Achieving precise animation end values?

    - by bobthabuilda
    I'm currently trying to write my own JavaScript library. I'm in the middle of writing an animation callback, but I'm having trouble getting precise end values, especially when animation duration times are smaller. Right now, I'm only targeting positional animation (left, top, right, bottom). When my animations complete, they end up having an error margin of 5px~ on faster animations, and 0.5px~ on animations 1000+ ms or greater. Here's the bulk of the callback, with notes following. var current = parseFloat( this[0].style[prop] || 0 ) // If our target value is greater than the current , gt = !!( value > current ) , delta = ( Math.abs(current - value) / (duration / 13) ) * (gt ? 1 : -1) , elem = this[0] , anim = setInterval( function(){ elem.style[prop] = ( current + delta ) + 'px'; current = parseFloat( elem.style[prop] ); if ( gt && current >= value || !gt && current <= value ) clearInterval( anim ); }, 13 ); this[0] and elem both reference the target DOM element. prop references the property to animate, left, top, bottom, right, etc. current is the current value of the DOM element's property. value is the desired value to animate to. duration is the specified duration (in ms) that the animation should last. 13 is the setInterval delay (which should roughly be the absolute minimal for all browsers). gt is a var that is true if value exceeds the initial current, else it is false. How can I resolve the error margin?
