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="i"><div class="a_">
<span wicket:id="indent"></span><a
wicket:id="link"><span wicket:id="image"/></a><span 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="link"><span 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 ?
Isaac
