Disappearing scroll bars

Question

All, I have developed a custom widget in which I dynamically add information to a vGroup from related records when the user clicks the map. Sometimes the number of records are more than the widget can display, so I added scroll bars to the widget. It struck me as odd that I had to add the scroll bars as I thought the widget would do this automatically. However, adding scroll bars worked the first time the user opens the widget. If the user closes the widget and then re-opens it again, the scroll bars do not appear. Anyone have clue why they do not appear when the widget is re-opened? Additional info: code Thanks, Dan

Dan,

You should be just setting the ArrayCollection that is the datadprovider for your datagroup to null.

Turns out the problem is using the removeAllElements() function on the resultsGroup unfortunately removes the scroll bar as well.  Now I need to know how to remove spedific elements from the VGroup as I close the widget.  This will allow the widget to look reset when the user calls it again.

Thanks,

Forum,

Additional detail.  While it remains true that the scroll bars are not visible, the scrolling functionallity works when I use the scroll wheel on the mouse.  It is as if the scrollbars themselves are outside the viewable area.  Any idea why this happens on the second instantiation of the widget, but not the first?

When the widget closes I remove all the elements within the vGroup(resultsGroup).  Could this impact the scroller which is the parent of the vGroup in some way?

Thanks,
Dan
