Re: PageStore Broken in 1.3.1?

Thu, 06 Mar 2008 04:05:50 -0800

Main idea was to ask, if Luke Ma already has? Problem occurs in one very massive page of ours and creating corresponding test case using basic wicket components takes time. I am not too enthusiastic to create one if Luke already has.

Anything happened in this case? We have same kind of problems.
Increasing the stack size just makes things work a little bit longer.
StackOverflowError occurs only in 1.3.1 not in 1.3.0

You could increase the stack size of your VM. It is one of the -X
parameters. It will at least give you a work around if it is a bug.

I think Wicket 1.3.1 introduced a bug in the PageStore.  I get a

stack

overflow with behaviors such as:

   * Click on a link and then click on a second link (on the same

page)

before the first one finishes processing.
   * On Firefox, click on a link to a page, then click back to go

back to

the first page, then click on any link.
   * In IE, click on some links, click the back button.

Stack trace below.  Maybe somebody familiar with the bowels of Wicket
PageStore can take a quick look to see if this is a bug?
