Open event doesn't fire


I have a webpage, in the open-event i add a web-container.
This web-container is shown on the page, but the open-event of the web-container doesn’t fire.
Creating the container in shown-event of webpage, the open-event fires.

This is not my fault!?!?!?

That doesn’t surprise me. We’ve been tracking down bugs with the Open and Shown events for a long time and this is an example of one that has slipped through the cracks. Please file a bug report so we don’t forget about it.
