Thanks Ryan, First pass this has worked well for me. Appreciate your detailed instructions. Maybe these can be added to the open issue history itself for other folks till the issue gets closed.
I assume you have to be developer to make changes to the change history. -ed > From: [EMAIL PROTECTED] > Subject: Re: modal window question - opening a modal window on page load > Date: Sun, 9 Sep 2007 22:24:03 -0700 > To: [email protected] > > There is an open issue about this: http://issues.apache.org/jira/ > browse/WICKET-12 > Read the discussion for some background and possible solutions. > > I needed to do the same thing on a couple of pages.
