Hi,
did you ever experience the fact that sometimes, typically the first time I use the control the event expand is not fired ?
I mean the panelbar correctly expands but the function attached as handler to the event is not called ?
Initialization seem to end correctly.
Thanks for any hint, or conditions that influence the issue of the event ?
Sorry can't say that I've experienced that before.
The only thing I can think of off the top of my head is whether or not you've set the default panel by using either JS or by applying the relevant CSS class to the HTML element?
