Hi All, I am having a problem laying out a qx.ui.form.List. I first noticed it in source version r4343 - but today I updated to r4822 and am having the same problem.
The problem occurs intermittently when adding qx.ui.form.List of qx.ui.form.ListItems to a CanvasLayout -- the 2nd area of a qx.ui.splitpane.HorizontalSplitPane. It always works fine the first time you add children. However, if you want to drop the list completely, and replace it with a new list it occassionally (approximately one time in 6 attempts) fails, and you see the following error messages on the console. Has anyone else seen this? Is there are known workaround or a bugfix?
