[Wt-interest] multiple tabs inside a dialog causes a crash

Joseph VanAndel Fri, 25 Sep 2009 13:51:18 -0700

I've attached a test program that creates a dialog containing multiple tabs. If I only create a single tab, the test program works. I'm using Wt from git, updated as of 2009/9/25. Here's part of the backtrace - note that item=0x0 in the routine that crashed.


Should I create the dialog differently, or is this a bug?
