Hi,
I need to reset certaing elements in a page while navigating in to it
from another page.
But doing so I am getting a EmptyStackException. Can someone help me
with this.
Looks like its trying to remove PageA from memory and failed to find it
in the stack.
Following is the code script inside PageA from where I am calling PageB.
@Override
public void finishLoad(IRequestCycle pCycle, IPageLoader pLoader,
IComponentSpecification pSpecification)
{
PageB page = (PageB)pCycle.getPage("pageB");
page.setClaim(null);
page.setInitialized(false);
throw new PageRedirectException(page);
}
and the stack trace shows
