I've been having a user presented exception that only seems to occur when
the moon is right.
I have the following page flow...
Home -> Client Select -> Create
Now if the user meets certain criteria the "Client Select" screen skips
the data entry and redirects to the user straight to the create page. As
such..
...
if (redirect)
{
IPage page =
event.getRequestCycle().getPage(CreateUCR.getEIPageName());
throw new PageRedirectException(page);
}
...
I haven't gotten a good repro case, and I can't figure out why, but
occasionally the PageRedirectException isn't caught by the tapestry
framework and handled instead it migrates up to the user, and the user is
displayed the exception page with the following...
An exception has occurred.
You may continue by restarting the session.
