  • Pagination in Tab Content of Jquery UI

    - by DR.GEWA
    I am making a page with Jquery UI TABS. In one of tabs I want to make pagination for comments. I want such thing. When user clicks on the number of the page, the data of the page , which is linked will load via ajax in the tab. Here is my code <script type="text/javascript"> $(function() { $("#tabs").tabs(); }); $('#demo').tabs({ load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); </script> How can I change this , so that any link inside the content with lets say with id "pagination" <a href="/coments?page=12&user_id=12" id="pagination">12</a> ?? Thanks beforehand I tried recently like this even and no luck. This is from http://www.bannerite.com/jquerytest/index2.php Here it work <script type="text/javascript"> $(function() { $("#tabs").tabs(); var hijax = function(panel){ $('a', panel).click(function() { /**makes children 'a' on panel load via ajax, hence hijax*/ $(panel).load(this.href, null, function(){ /**recursively apply the hijax to newly loaded panels*/ hijax(panel); }); /**prevents propagation of click to document*/ return false; }); $('form', panel).css({background: 'yellow'}).ajaxForm({ target: panel, }); }; $('#demo ul').tabs({ /**initialize the tabs hijax pattern*/ load: function(tab, panel) { hijax(panel); } }); }); </script> HEre are the HTML part as Karl gived , but no succes. When clicking on Test link its going to another page........ When clicking on I wanted to post HTML here but because of users with less reputation <10 cant give HTML with links I have posted it here http://gevork.ru/2009/12/31/jquery-ui-tab-and-pagination-html/#more-58

  • Confused about home screen widget size in normal screen and larget screen

    - by kknight
    I am designing a home screen widget. The widget layout file is like below. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget" android:layout_width="240dip" android:layout_height="200dip" android:background="@drawable/base_all" /> I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels. Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device. I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing? Thanks.

  • function not working R

    - by user3722828
    I've never programmed before and am trying to learn. I'm following that "coursera" course that I've seen other people post about — a course offered by Johns Hopkins on R programming. Anyway, this was supposed to be my first function. Yet, it doesn't work! But when I type out all the steps individually, it runs just fine... Can anyone tell me why? > pollutantmean <- function(directory, pollutant, id = 1:332){ + x<- list.files("/Users/mike******/Desktop/directory", full.names=TRUE) + y<- lapply(x, read.csv) + z<- do.call(rbind.data.frame, y[id]) + + mean(z$pollutant, na.rm=TRUE) + } > pollutantmean(specdata,nitrate,1:10) [1] NA Warning message: In mean.default(z$pollutant, na.rm = TRUE) : argument is not numeric or logical: returning NA #### > x<- list.files("/Users/mike******/Desktop/specdata",full.names=TRUE) > y<- lapply(x,read.csv) > z<- do.call(rbind.data.frame,y[1:10]) > mean(z$nitrate,na.rm=TRUE) [1] 0.7976266

  • Positioning Layers and text gradients with css

    - by Kenji Crosland
    I'm a CSS newbie trying to get some text gradients going on. I tried this code here but it didn't work for me, most likely because the h1 object is nested within a #header div. I imagine there's something to do with layers that I don't know about. Either I get a gradent block that is in front of everything or it's not appearing at all. In this particular instance this code makes a big gradient bar appear in front of everything: #header { clear:both; float:left; -moz-background-inline-policy:continuous; -moz-background-origin:padding; background:#080E73 url(../images/header-background.png) repeat-x left 0px; width:100%; max-height: 175px; color: #080E73; } #header h1 { margin-bottom: 0; color: #000; position: relative; } #header h1 span { background:url(../images/headline-text.png) repeat-x; display: block; width: 100%; height: 100%; position: absolute; } Here is the HTML (I'm using ruby on rails hence the notation) <div id="header"> <% unless flash[:notice].blank? %> <div id="notice"><%= flash[:notice] %></div> <% end %> <%= image_tag ("header-image.png") %> <h1><span></span>Headline</h1> <strong>Byline</strong> ... #navbar html... </div> I tried playing with z-index but I couldn't come up with any good results. Any ideas?

  • How do I point a ListFieldIterator to a subweb when ControlMode = Display?

    - by Rich Bennema
    I have a custom page with the following ListFieldIterator: <SharePoint:ListFieldIterator runat="server" ControlMode="Display" OnInit="listFieldIterator_Init" /> Here is the Init event: protected void listFieldIterator_Init(object sender, EventArgs e) { ListFieldIterator listFieldIterator = sender as ListFieldIterator; SPContext current = SPContext.Current; SPFieldUrlValue value = new SPFieldUrlValue(current.ListItem[SPBuiltInFieldId.URL].ToString()); Uri uri = new Uri(value.Url); using (SPWeb web = current.Site.OpenWeb(uri.AbsolutePath)) { SPListItem item = web.GetListItem(uri.PathAndQuery); if (null != item) { listFieldIterator.ItemContext = SPContext.GetContext(this.Context, item.ID, item.ParentList.ID, web); } } } Everything works great if the target List Item is in the same site as the page. But once it points to a different site, all the fields appear, but the values all appear in the following format: Failed to render "Title" column because of an error in the "Single line of text" field type control. See details in log. Exception message: List does not exist The page you selected contains a list that does not exist. It may have been deleted by another user.. If I change the ControlMode to Edit, the values are displayed correctly. So how do I get it to work while in Display mode?

  • ListView item background via custom selector

    - by Gil
    Is it possible to apply a custom background to each Listview item via the list selector? The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible. I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place. For reference, this is the selector I'm using to try and get this working: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="false" android:drawable="@drawable/list_item_gradient" /> <!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. --> <item android:state_focused="true" android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_enabled="false" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="true" android:drawable="@drawable/list_selector_background_focus" /> </selector> And this is how I'm setting the selector: <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:listSelector="@drawable/list_selector_background" /> Thanks in advance for any help!

  • nhibernate will not cascade delete childs

    - by marn
    The scenario is as follows, I have 3 objects (i simplified the names) named Parent, parent's child & child's child parent's child is a set in parent, and child's child is a set in child. mapping is as follows (relevant parts) parent <set name="parentset" table="pc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column=FK_ID_PC" on-delete="cascade"/> <one-to-many class="parentchild,parentchild-ns"/> </set> parent's child <set name="childset" table="cc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column="FK_ID_CC" on-delete="cascade"/> <one-to-many class="childschild,childschild-ns"/> </set> What i want to achieve is that when i delete the parent, there would be a cascade delete all the way trough to child's child. But what currently happens is this. (this is purely for mapping test purposes) getting a parent entity (works fine) IQuery query = session.CreateQuery("from Parent where ID =" + ID); IParent doc = query.UniqueResult<Parent>(); now the delete part session.Delete(doc); transaction.Commit(); After having solved the 'cannot insert null value' error with cascading and inverse i hopes this would now delete everything with this code, but only the parent is being deleted. Did i miss something in my mapping which is likely to be missed? Any hint in the right direction is more than welcome!

  • Recursion in an ASP.NET MVC view

    - by Dennis Palmer
    I have a nested data object for a set of items within categories. Each category can contain sub categories and there is no set limit to the depth of sub categories. (A file system would have a similar structure.) It looks something like this: class category { public int id; public string name; public IQueryable<category> categories; public IQueryable<item> items; } class item { public int id; public string name; } I am passing a list of categories to my view as IQueryable<category>. I want to output the categories as a set of nested unordered list (<ul>) blocks. I could nest foreach loops, but then the depth of sub categories would be limited by the number of nested foreach blocks. In WinForms, I have done similar processing using recursion to populate a TreeView, but I haven't seen any examples of using recursion within an ASPX MVC view. Can recursion be done within an ASPX view? Are there other view engines that include recursion for view output?

  • sqlalchemy date type in 0.6 migration using mssql

    - by nosklo
    I'm connection to mssql server through pyodbc, via FreeTDS odbc driver, on linux ubuntu 10.04. Sqlalchemy 0.5 uses DATETIME for sqlalchemy.Date() fields. Now Sqlalchemy 0.6 uses DATE, but sql server 2000 doesn't have a DATE type. How can I make DATETIME be the default for sqlalchemy.Date() on sqlalchemy 0.6 mssql+pyodbc dialect? I'd like to keep it as clean as possible. Here's code to reproduce the issue: import sqlalchemy from sqlalchemy import Table, Column, MetaData, Date, Integer, create_engine engine = create_engine( 'mssql+pyodbc://sa:sa@myserver/mydb?driver=FreeTDS') m = MetaData(bind=engine) tb = sqlalchemy.Table('test_date', m, Column('id', Integer, primary_key=True), Column('dt', Date()) ) tb.create() And here is the traceback I'm getting: Traceback (most recent call last): File "/tmp/teste.py", line 15, in <module> tb.create() File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/schema.py", line 428, in create bind.create(self, checkfirst=checkfirst) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1647, in create connection=connection, **kwargs) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1682, in _run_visitor **kwargs).traverse_single(element) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/sql/visitors.py", line 77, in traverse_single return meth(obj, **kw) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/ddl.py", line 58, in visit_table self.connection.execute(schema.CreateTable(table)) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1157, in execute params) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1210, in _execute_ddl return self.__execute_context(context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1268, in __execute_context context.parameters[0], context=context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1367, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1360, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/default.py", line 277, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.ProgrammingError: (ProgrammingError) ('42000', '[42000] [FreeTDS][SQL Server]Column or parameter #2: Cannot find data type DATE.

  • Problem with custom Equality in Entity Framework

    - by Shimmy
    Hello! I am using Entity Framework in my application. I implemented with the partial class of an entity the IEquatable<T> interface: Partial Class Address : Implements IEquatable(Of Address) 'Other part generated Public Overloads Function Equals(ByVal other As Address) As Boolean _ Implements System.IEquatable(Of Address).Equals If ReferenceEquals(Me, other) Then Return True Return AddressId = other.AddressId End Function Public Overrides Function Equals(ByVal obj As Object) As Boolean If obj Is Nothing Then Return MyBase.Equals(obj) If TypeOf obj Is Address Then Return Equals(DirectCast(obj, Address)) Else Return False End Function Public Overrides Function GetHashCode() As Integer Return AddressId.GetHashCode End Function End Class Now in my code I use it this way: Sub Main() Using e As New CompleteKitchenEntities Dim job = e.Job.FirstOrDefault Dim address As New Address() job.Addresses.Add(address) Dim contains1 = job.Addresses.Contains(address) 'True e.SaveChanges() Dim contains2 = job.Addresses.Contains(address) 'False 'The problem is that I can't remove it: Dim removed = job.Addresses.Remoeve(address) 'False End Using End Sub Note (I checked in the debugger visualizer) that the EntityCollection class stores its entities in HashSet so it has to do with the GetHashCode function, I want it to depend on the ID so entities are compared by their IDs. Please help me find what's wrong in the GetHashCode function (by ID) and what can I change to make it work. Thanks a lot.

  • NHibernate: Mapping different dynamic components based on a discriminator

    - by George Mauer
    My domain entities each have a set of "fixed" properties and a set of "dynamic" properties which can be added at runtime. I handle this by using NHibernate's dynamic-component functionality. public class Product { public virtual Guid Id { get; } public virtual string Name { get; set;} public virtual IDictionary DynamicComponents { get; } } Now I have the following situation public class Customer { public virtual Guid Id { get; } public virtual string Type { get; set;} public virtual IDictionary DynamicProperties { get; } } Where a CustomerType is something like "Online" or "InPerson". Furthermore an Online customer has dynamic properties "Name" and "IPAddress" and an InPerson Customer has dynamic properties "Name" and "Salesman". Which customer types are available and the extra properties on them are configured in meta-data which is used to generate hbm files on application start. I could figure out some way to knock this together using an intermediate DTO layer, but is there any support in NHibernate for this scenario? The only difficulty seems to be that all the different "types" of customer map to the same Customer class.

  • Redirect from URL with QueryString to the same URL without QueryString

    - by Slauma
    I have a page request with a QueryString, say http://www.xyz.net/Orders.aspx?OrderID=1. The page is displayed in a browser. Now there is an asp:LinkButton on the page which should enable the user to open the page without the QueryString (as if he had entered http://www.xyz.net/Orders.aspx directly in the browser's address bar). I had two ideas: 1) Use the PostBackUrl attribute of the LinkButton: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" PostBackUrl="~/Orders.aspx" /> 2) Use "RedirectUrl" in an event handler: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" OnClick="LinkButton1_Click" /> ...and... protected void LinkButton1_Click(object sender, EventArgs e) { Response.Redirect("~/Orders.aspx"); } In both cases the browser's address bar shows http://www.xyz.net/Orders.aspx without the QueryString, as I like to have it. But in the first case the page does not change at all. But it should, because I'm evaluating the QueryString in code-behind and control the appearance of the page depending on whether a QueryString exists or not. The second option works as intended. If I am not wrong the second option requires an additional roundtrip: Browser sends request to server Event handler on server side sends Redirect URL to browser Browser sends again request to the server, but with the new URL Server sends new requested page to browser Is this correct at all? Whereas the first option omits the first two steps in the list above, thus saving the additional roundtrip and resulting in: Browser sends request to the server, but with the new URL (the PostbackURL specified in the LinkButton) Server sends new requested page to browser But, as said, the result isn't the same. I'm sure my try to explain the differences between the two options is wrong somewhere. But I don't know where exactly. Can someone explain what's really the difference? Do I really need this second roundtrip of option (2) to achieve what I want? Thanks in advance!

  • "The name 'WithTable' does not exist in the current context" using Fluent NHibernate

  • Populating Models from other Models in Django?

    - by JT
    This is somewhat related to the question posed in this question but I'm trying to do this with an abstract base class. For the purposes of this example lets use these models: class Comic(models.Model): name = models.CharField(max_length=20) desc = models.CharField(max_length=100) volume = models.IntegerField() ... <50 other things that make up a Comic> class Meta: abstract = True class InkedComic(Comic): lines = models.IntegerField() class ColoredComic(Comic): colored = models.BooleanField(default=False) In the view lets say we get a reference to an InkedComic id since the tracer, err I mean, inker is done drawing the lines and it's time to add color. Once the view has added all the color we want to save a ColoredComic to the db. Obviously we could do inked = InkedComic.object.get(pk=ink_id) colored = ColoredComic() colored.name = inked.name etc, etc. But really it'd be nice to do: colored = ColoredComic(inked_comic=inked) colored.colored = True colored.save() I tried to do class ColoredComic(Comic): colored = models.BooleanField(default=False) def __init__(self, inked_comic = False, *args, **kwargs): super(ColoredComic, self).__init__(*args, **kwargs) if inked_comic: self.__dict__.update(inked_comic.__dict__) self.__dict__.update({'id': None}) # Remove pk field value but it turns out the ColoredComic.objects.get(pk=1) call sticks the pk into the inked_comic keyword, which is obviously not intended. (and actually results in a int does not have a dict exception) My brain is fried at this point, am I missing something obvious, or is there a better way to do this?

  • Can't get NSTableView to display data.

    - by Alberto
    Hi! I see there are a lot of questions about this, but nothing helped me to get this work. I have a nib with a NSTableView with three columns (with the right identifiers set) and a class named ShortcutsTableController. In the nib I have a NSObject with class value ShortcutsTableController. I also connected the NSTableView to my controller as I usually do. This is header ShortcutsTableController.h. #import <Cocoa/Cocoa.h> @interface ShortcutsTableController : NSObject <NSTableViewDataSource> { IBOutlet NSTableView *shortcutsTable; NSMutableArray *shortcutsList; } - (int) numberOfRowsInTableView: (NSTableView*) tableView; - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row; @property (assign) IBOutlet NSTableView *shortcutsTable; - (void)setUpTable; @end And this is the implementation file ShortcutsTableController.m. #import "ShortcutsTableController.h" @implementation ShortcutsTableController @synthesize shortcutsTable; - (void)setUpTable { shortcutsList = [[NSMutableArray alloc] init]; NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys: @"blabla", @"nameColumn", @"Bla bla bla", @"shortcutColumn", @"Ribla", @"actionColumn", nil]; [shortcutsList addObject:dict1]; [shortcutsTable setDataSource:self]; [shortcutsTable reloadData]; } -(int) numberOfRowsInTableView: (NSTableView *) tableView { return [shortcutsList count]; } - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row { if (row != -1) return [[shortcutsList objectAtIndex:row] objectForKey:[tableColumn identifier]]; return nil; } @end But when i try to build nothing appears in the NSTableView. No errors, no warnings. Note that I call setUpTable from within the Delegate Class Method awakeFromNib. Is there something I am doing wrong? Thank you for you help. —Albé UPDATE. Added lines @property (assign) IBOutlet NSTableView *shortcutsTable; in header and @synthesize shortcutsTable; in implementation. Nothing changes. :(

  • How can I use external expressions in Linq with EF4 (and LINQKit)?

    - by neo
    I want to separate out often used expressions in linq queries. I'm using Entity Framework 4 and also LINQKit but I still don't know how I should do it the right way. Let me give you an example: Article article = dataContainer.Articles.FirstOrDefault(a => a.Id == id); IEnumerable<Comment> comments = (from c in container.Comments where CommentExpressions.IsApproved.Invoke(c) select c); public static class CommentExpressions { public static Expression<Func<Module, bool>> IsApproved { get { return m => m.IsApproved; } } } Of course the IsApproved expression would be something much more complicated. The problem is that the Invoke() won't work because I didn't call .asExpandable() from LINQKit on container.Comments but I can't call it because it's just an ICollection instead of an ObjectSet. So my question is: Do I always have to go through the data context when I want to include external expressions or can I somehow use it on the object I fetched (Article)? Any ideas or best practices? Thanks very much! neo

  • Rails Associations - Callback Sequence/Magic

    - by satynos
    Taking following association declaration as an example: class Post has_many :comments end Just by declaring the has_many :comments, ActiveRecord adds several methods of which I am particularly interested in comments which returns array of comments. I browsed through the code and following seems to be the callback sequence: def has_many(association_id, options = {}, &extension) reflection = create_has_many_reflection(association_id, options, &extension) configure_dependency_for_has_many(reflection) add_association_callbacks(reflection.name, reflection.options) if options[:through] collection_accessor_methods(reflection, HasManyThroughAssociation) else collection_accessor_methods(reflection, HasManyAssociation) end end def collection_accessor_methods(reflection, association_proxy_class, writer = true) collection_reader_method(reflection, association_proxy_class) if writer define_method("#{reflection.name}=") do |new_value| # Loads proxy class instance (defined in collection_reader_method) if not already loaded association = send(reflection.name) association.replace(new_value) association end define_method("#{reflection.name.to_s.singularize}_ids=") do |new_value| ids = (new_value || []).reject { |nid| nid.blank? } send("#{reflection.name}=", reflection.class_name.constantize.find(ids)) end end end def collection_reader_method(reflection, association_proxy_class) define_method(reflection.name) do |*params| force_reload = params.first unless params.empty? association = association_instance_get(reflection.name) unless association association = association_proxy_class.new(self, reflection) association_instance_set(reflection.name, association) end association.reload if force_reload association end define_method("#{reflection.name.to_s.singularize}_ids") do if send(reflection.name).loaded? || reflection.options[:finder_sql] send(reflection.name).map(&:id) else send(reflection.name).all(:select => "#{reflection.quoted_table_name}.#{reflection.klass.primary_key}").map(&:id) end end end In this sequence of callbacks, where exactly is the actual SQL being executed for retrieving the comments when I do @post.comments ?

  • Ajax actionlinks straight from a DropDownList

    - by Ingó Vals
    I've got a small linkbox on the side of my page that is rendered as a PartialView. In it I have a dropDownlist the should change the routing value of the links in the box but I'm having difficulty doing so. My current plan is to call on something similar to a Ajax.ActionLink to reload the partial view into the with a different parameter based on the value of the dropdown selection. However I'm having multiple problems with this, for example as a novice in using dropdownlists I have no idea how to call on the selected value for example. <%= Html.DropDownList("DropDownList1", new SelectList(Model, "ID", "Name"), "--Pick--", new { AutoPostBack = "true", onchange = "maybe something here" })%> I tried putting in the sys.mvc.AsyncHyperlink into the onchange attribute and that worked except I don't know how to put in the route value for it. Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'SmallMenu' } Is there no straight Ajax drop down list that fires events onchange? Any way this is possible? I have later in the Partial view the Ajax actionlinks but they need to have their id's updated by the value in the dropdownlist and if I could do that somehow else I would appreciate a suggestion.

  • Safari flash wmode not working - anything wrong with this embed?

    - by hfidgen
    I've got a problem with this embed in Safari. It works just fine on all other browsers, IE6 included. The problem is that the embed seems to jump to the very top layer, ignoring all z-index or positioning statements. This is important, because several html design features are overlayed on the flash. This embed was written to work with swfobject, but still doesnt work when: swfobject disabled wmode = transparent/opaque/removed entirely Is this a problem with safari or the code? And if it's the code then what does safari do differently to all the other browsers? Bah. Thanks for any help ;) <object id="Flash_Banner" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="950" height="400" title=""> <param name="movie" value="ui.swf" /> <param name="quality" value="high" /> <param name="wmode" value="opaque" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="ui.swf" width="950" height="400" title=""> <param name="quality" value="high" /> <param name="wmode" value="opaque" /> <!--<![endif]--> <div id="banner_slider"><img src="images/banners/case.jpg" width="950" height="400" alt="" /></div> <!--[if !IE]>--> </object> <!--<![endif]--> </object>

  • Spring Test / JUnit problem - unable to load application context

    - by HDave
    I am using Spring for the first time and must be doing something wrong. I have a project with several Bean implementations and now I am trying to create a test class with Spring Test and JUnit. I am trying to use Spring Test to inject a customized bean into the test class. Here is my test-applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="............."> <bean id="MyUuidFactory" class="com.myapp.UuidFactory" scope="singleton" > <property name="typeIdentifier" value="CLS" /> </bean> <bean id="ThingyImplTest" class="com.myapp.ThingyImplTest" scope="singleton"> <property name="uuidFactory"> <idref local="MyUuidFactory" /> </property> </bean> </beans> The injection of MyUuidFactory instance goes along with the following code from within the test class: private UuidFactory uuidFactory; public void setUuidFactory(UuidFactory uuidFactory) { this.uuidFactory = uuidFactory; } However, when I go to run the test (in Eclipse or command line) I get the following error (stack trace omitted for brevity): Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyImplTest' defined in class path resource [test-applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'com.myapp.UuidFactory' for property 'uuidFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.myapp.UuidFactory] for property 'uuidFactory': no matching editors or conversion strategy found Funny thing is, the Eclipse/Spring XML editor shows errors of I misspell any of the types or idrefs. If I leave the bean in, but comment out the dependency injection, everything work until I get a NullPointerException while running the test...which makes sense.
