I'm facing an issue with the flex Application I'm currently working on.
When I open a pop-up using the 'createPopUp' method, I've got this index out of bounds error message :
RangeError: The supplied index is out of bounds. at

It seems that this error is caused by a "dateChooser" component in my popup :
<mx:DateChooser id="endDate"/>
When I comment this line, the error is no longer thrown and the popup loads correctly.
It's really weird because I didn't have this issue until this morning. All I did in the meantime was changing some layout-related stuff, but I don't see what is would have to do with this problem.
I don't get it...
Does anyone have a clue about how to fix this ? I need my DateChooser !
Thanks !
Laura
EDIT -
It seems that the problem is not caused by the DateChooser itself, but by the FormItem around it. Here's what my code looks like :
<Form width="100%">
[...]
<s:HGroup width="100%">
<s:FormItem label="Date de début">
<mx:DateChooser id="startDate"
firstDayOfWeek="1"/>
</s:FormItem>
<s:FormItem label="Date de fin">
<mx:DateChooser id="endDate"
firstDayOfWeek="1"/>
</s:FormItem>
</s:HGroup>
</Form>
If I remove the two FormItems, it works. Could anyone explain me why? Thanks !
