Re: [Wicket-user] No Page found for component after selecting TreeNode
Thanks for the quick replay. After some digging, I found that I forgot to check that TreeItem is also a WebMarkupContainer which is rebuilt. A wrong way to re-implement my requirement in the Tree component let me think it worked on the Tree component in wicket-extension, which is obvious not after some serious thought. Seems like I asked a dumb question, hah Isaac Matej Knopp wrote: When tree node is selected the appropriate part of tree is rebuilt, which also involves recreating the components.

[Wicket-user] No Page found for component after selecting TreeNode
Hi,
Similar to ILinkCallback of Tree in wicket-extension, I created a
callback link which allows me to select a tree node in my custom Link
component. After the link is clicked, the callback is executed and the
node is selected. However, after selectNode() runs, getPage() in the
Link component results in No Page found for component. Following is a
brief sample code:
MyTree.html:
wicket:panel
div class=wicket-tree
div wicket:id=idiv class=a_
span wicket:id=indent/spana
wicket:id=linkspan wicket:id=image//aspan wicket:id=myPanel /
/div/div/div
/wicket:panel
MyTree.java:
public class MyTree extends DefaultAbstractTree
{
...
protected void populateTreeItem(final WebMarkupContainer item,
int level)
{
...
final DefaultMutableTreeNode node = (DefaultMutableTreeNode)
item.getModelObject();
add(new MyPanel(myPanel, item.getModelObject(), new
IMyLinkCallback()
{
public void onClick(AjaxRequestTarget target)
{
getTreeState().selectNode(node,
!getTreeState().isNodeSelected(node));
}
});
}
MyPanel.html:
wicket:panel
a wicket:id=linkspan wicket:id=outputName/span/a
/wicket:panel
MyPanel.java:
public class MyPanel extends Panel
{
public MyPanel(String id, Object object, final IMyLinkCallback
callback)
{
super(id);
Link myLink = new Link(link)
{
public void onClick()
{
getPage(); // return the Page instance correctly.
callback.onClick(null);
getPage(); // No Page found for component
}
};
DefaultMutableTreeNode node = (DefaultMutableTreeNode) object;
myLink.add(new Label(outputName, (String)
node.getUserObject()));
add(myLink);
}
}
IMyLinkCallback.java:
public interface IMyLinkCallback extends IClusterable
{
public void onClick(AjaxRequestTarget target);
}
The problem appears in both 1.3.0 of April 4, and 1.2.5. Am I doing
it in a wrong way ?

[Wicket-user] Strange problem with ModalWindow
Hi, The problem happens after upgrading to 1.3.0-SNAPSHOT on 1 April. I have a right panel replaced by another panel with ajax tabs by click on a link in the left panel. In the second tab, there's a button which will open a modal window when clicked. The problem is that sometimes an exception threw after the button clicked or during modal window redering, which is the cause I'm not sure. The strange part is the exception isn't thrown every time, and I can't find a right way to reproduce it. In Jetty, it's a EofException, however in Tomcat it says Broken pipe. No refresh or any link is clicked while rendering the modal window, so I have no idea where broken pipe occured from. Also, the problem seems only happens in IE. In development mode, if the exception threw, after closing the modal window, another WicketRuntimeException is thrown saying something like component form:modal not found on page However in deployment mode, the WicketRuntimeException won't be thrown. There's no such problem with 1.2.5 release. The attachment are logs from Jetty and Tomcat, and the quick-start sample, but the exception rarely threw in my sample, which really confuses me. Sorry for not able to find a good way to reproduce the problem. Any suggestion is appreciated.

[Wicket-user] Problem with ajax tree and listView
Hi,
This is my first time asking questions here.
Hope I can make my question clear.
I'v tried to extend the ajax tree in the wicket extension. The only
modification I made is the output value, which is a customized panel
instead of a label. Following are my html and source.
MyTree.html :
span wicket:id=indent/spana wicket:id=linkspan
wicket:id=image//a
a wicket:id=nodeLinkspan class=icon
wicket:id=icon/spanspan wicket:id=myPanel /
To simplify the problem, I strip most markups of MyPanel.html to
what I think causing the problem.
MyPanel.html :
span wicket:id=outputListspan
wicket:id=outputNamename/span/span
MyPanel.java :
public MyPanel extends Panel
{
public MyPanel(String id)
{
super(id);
ArrayListString list = new ArrayListString();
list.add(name1);
add(new ListView(outputList, list)
{
public void populateItem(final ListItem item)
{
final String name = (String) item.getModelObject();
item.add(new Label(outputName, name));
}
});
}
}
The problem is while I click the junction link,
ListView.renderItem() throws a NullPointerException. After some digging,
I found that the ListItem is null. Then I use getList(), and it
successfully return the list I passed in and the values in that list are
also correct, however the ListItem is null which I don't know why.
Thanks for reading my question. I will appreciate any suggestions.
Isaac
