1. If the same code produces different character bounds in AIR than in the Flash Player, that's a bug and you should file it. 2. A constructor should not call createChildren(). The framework automatically calls createChildren() at the appropriate time, which is when the component is added to the display list. 3. If you find yourself having to use callLater(), you're probably doing something the wrong way. In general, you should use events rather than just waiting awhile. If the framework doesn't provide the event you need, please file an enhancement request. Gordon Smith Adobe Flex SDK Team

Great, it seems like callLater saved my butt. Luckily i also found the blog which explains in short the WHY's and HOW's of the callLater. Title of the blog is callLater() - The Function That Saved My Butt. It's here: http://www.kylehayes.info/blog/index.cfm/2007/5/31/callLater--The-Functi on-That-Saved-My-Butt <http://www.kylehayes.info/blog/index.cfm/2007/5/31/callLater--The-Funct ion-That-Saved-My-Butt> The function actually broke because I had to use it within the for loop. The solution was to to get rid of the for loop and instead split the iteration into several functions that were calling each other upon completion. --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Daniel Freiman" <[EMAIL PROTECTED]> wrote: > > If you want a simple wait, you can use uicomponent.callLater().
