Re: Design question : accessing components between panels
Hi, I had tried getPage() but it returns null to me. Is it because the panel in which I am trying to access the other panel component is a modal dialog? Any suggestions. igor.vaynberg wrote: component#getPage() -igor On Tue, Nov 4, 2008 at 9:28 PM, Arun Wagle [EMAIL PROTECTED] wrote: Hello , I have an application which renders a page.

Re: Design question : accessing components between panels
Whenever getPage() returns null it's most likely that the component isn't added to a page yet. Just a guess: you're calling getPage() in the constructor of your panel right? Try calling it in the onBeforeRender method and page won't return null hope that helps Michael Arun Wagle wrote: Hi, I had tried getPage() but it returns null to me.

Each panel has some components in it.

What exactly do you want to do with the panel B component in
panel A?
Can someone tell me how do I get a handle to panel B in panel A ?
getPage().visitChildren(PanelB.class, new IVisitor() {
...
});
Can someone please help me as I have lot of cases with these scenarious ?
Then you could have a look at
https://issues.apache.org/jira/browse/WICKET-1312
and the blog posts referenced in it.
There has also been a lot of discussion of these scenarios
on this mailing list before, so you could search Nabble on
that.
Best wishes,
Timo
