Re: [Wicket-user] More CSS support in wicket?

[Wicket-user] Overriding ListView#getListItemModel
The javadoc of the getListItemModel method of the abstract class ListView states that Subclasses may provide their own ListItemModel with extended functionality. The default ListItemModel works fine with mostly static lists where index remains valid. In cases where the underlying list changes a lot (many users using the application), it may not longer be appropriate. In that case your own ListItemModel implementation should use an id (e.g. the database' record id) to identify and load the list item model object... I am in situation where the list is not static and the application is used by many users.. Can you provide a sample implementation of the getListItemModel method for this situation?

Re: [Wicket-user] Overriding ListView#getListItemModel
Default the listmodel just stored the index of the list of the ListViewAnd then gets the object from the ListViews list back by that index.But if the list changes the index will return a different object then that ListItem was rendered with. So what you need to do is replace that index with something else.That is mostly the PK/ID of the object. So you keep that in your listmodel.and then when you want the object back. You don't go to the list and get it by index but get it by PK/ID (you don't even have to use the list at all anymore just query it)For database dynamic list you should use in wicket extentions and then the repeater package.There we have much better implementations for repeating things. johanOn 7/20/06, Alex Objelean [EMAIL PROTECTED] wrote: The javadoc of the getListItemModel method of the abstract class ListViewstates that Subclasses may provide their own ListItemModel with extendedfunctionality.

Hi I think I might have discovered a bug. I had a checkbox with some ajax behaviour. On the same page I also had a panel which had some form components in it, one of the components did also use ajax. I set visible(false) on the checkbox and 3 things happened 1. checkbox was no longer rendered(surpriseJ) 2. wicket debug for ajax was no longer rendered 3. ajax behaviour on the other component stopped working So I removed ajaxbehavior on the checkbox then it all worked again.

[Wicket-user] Changing visibility via ajax
I want to change visibility attribute of a panel (containing other components) using Ajax. The panel initially is hidden panel.setVisible( false ).When user change selection in a radio group the panel should become visible.
I've tried to do something like that :radio.add( new AjaxFormComponentUpdatingBehavior(onclick) {
protected void onUpdate(AjaxRequestTarget target) {
panel.setVisible( true );
target.addComponent(panel); }
} );But it don't work. Using the AJAX Debugger I could see that event is raised but it reports the following error:
ERROR: Component with id [[form1_panel]] a was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update.
ERROR: error while processing response: [object Error].Object requiredObviuosly I used setOutputMarkupId(true) on panel.
Any idea why it don't work?Thanks for helping.- Paolo

Re: [Wicket-user] Changing visibility via ajax
the problem is that if the panel is hidden initially it doesnt have its div/span tag with an id attribute in the markup, so the ajax request cannot find the tag to redraw.in situations like this you have to wrap the panel in a webmarkupcontainer, call setoutputmarkupid(true) on it, and target that container in your ajax target.
that way the container will be drawn initially empty : span id=container/span and when you make your panel visible it will contain the panel span id=containerspan id=panel/span/span

I seem to be getting random session expirations ( my session-timeout is set to 60 ) Error is below: WicketMessage: Method onNewBrowserWindow of interface wicket.markup.html.INewBrowserWindowListener targeted at component [Page class = wicket.markup.html.pages.InternalErrorPage, id = 5] threw an exception Root cause: java.lang.NullPointerException at wicket.PageMap.removeEntry(PageMap.java:335) at wicket.PageMap$1.entry(PageMap.java:197) at wicket.PageMap.visitEntries(PageMap.java:580) at wicket.PageMap.clear(PageMap.java:193) at wicket.PageMap.remove(PageMap.java:308) at wicket.Session.newPageMap(Session.java:581) at wicket.Session.createAutoPageMap(Session.java:474) at wicket.markup.html.WebPage.onNewBrowserWindow(WebPage.java:343) at java.lang.reflect.Method.invoke(Method.java:585) at wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:163) at wicket.request.target.component.listener.ListenerInterfaceRequestTarget.processEvents(ListenerInterfaceRequestTarget.java:74) at wicket.request.compound.DefaultEventProcessorStrategy.processEvents(DefaultEventProcessorStrategy.java:65) at wicket.request.compound.AbstractCompoundRequestCycleProcessor.processEvents(AbstractCompoundRequestCycleProcessor.java:57) at wicket.RequestCycle.doProcessEventsAndRespond(RequestCycle.java:846) at wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:879) at wicket.RequestCycle.step(RequestCycle.java:960) at wicket.RequestCycle.steps(RequestCycle.java:1034) at wicket.RequestCycle.request(RequestCycle.java:453) at wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:215) at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:54) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:174) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:199) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:282) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:754) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:684) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:876) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) Complete stack: wicket.WicketRuntimeException: Method onNewBrowserWindow of interface wicket.markup.html.INewBrowserWindowListener targeted at component [Page class = wicket.markup.html.pages.InternalErrorPage, id = 5] threw an exception at wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:174) at wicket.request.target.component.listener.ListenerInterfaceRequestTarget.processEvents(ListenerInterfaceRequestTarget.java:74) at wicket.request.compound.DefaultEventProcessorStrategy.processEvents(DefaultEventProcessorStrategy.java:65) at wicket.request.compound.AbstractCompoundRequestCycleProcessor.processEvents(AbstractCompoundRequestCycleProcessor.java:57) at wicket.RequestCycle.doProcessEventsAndRespond(RequestCycle.java:846) at wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:879) at wicket.RequestCycle.step(RequestCycle.java:960) at
[Wicket-user] Retaining values from one page view to the next
Apologies for another basic Wicket question... I understand (mostly) how the Wicket model approach works with respect to components and such. However, how do I retain values from one page view to the next? I know that I could use PageParameters, but the object I want to retain in a complex object and I don't want the trouble. I tried using PropertyModel( this, path), and tried PropertyModel.setObject( this, object ) to update the value, but that didn't work. I'm sure this is simple, but any hints would be greatly appreciated! Thank you! David PS - I tried searching on the archive, but the SourceForge archive is hopeless for searching... - Take Surveys.

Re: [Wicket-user] Retaining values from one page view to the next
all you have to do is pass the reference of the old page to the new pageclass ListUsersPage extends Webpage { . add(new Link(edit) { onclick() { setResponsePage(new EditUserPage(
ListUsersPage.this, (User)getModelObject())); }}class EditUserPage extends WebPage { public EditUserPage(final WebPage backPage, User user) { Form form; add(form=new Form(form, ));
form.add(new Button(save) { onsubmit() { //save user setResponsePage(backPage); === navigates to the list users page in its previous state
});}}hope this helps-IgorOn 7/20/06, David Leangen [EMAIL PROTECTED]

[Wicket-user] wicket.markup.html.tree.Tree is not suitable for very big tree
Hi, I find that the implementation of Wicket.markup.html.tree.Tree is not suitable for big tree. It seems because it depends on javax.swing.tree.DefaultMutableTreeNode too much, which asks for populating the whole tree before rendering Wicket.markup.html.tree.Tree. For my case, the tree is very big but users just click on some tree paths, so I hope I can just populate the tree step by step. However, this seems impossible because Wicket.markup.html.tree.Tree renders the tree based on the 'children' field in javax.swing.tree.DefaultMutableTreeNode, which I populate in the TreeModel's method getChildCount(Object parent). But this way does not work. Any suggestion? Regards,Rice - Take Surveys. Earn Cash.
