Hmmm... well, since a column resize ends up displaying the data it
certainly sounds like you are missing an invalidate. A couple of other
things to try: invalidateDisplayList on the grid, or refresh() on the
ArrayCollection after you alter the data. The following code may not be
optimal... but, it works every time regardless of whether I put zero
items into the ArrayCollection or actually have some items to put in
there. Note: I have to do a validateNow() for my resetting of the
scroll position to work. But, I don't think it is necessary otherwise.
//save off the vertical scroll position
var vScrollPos:int =
this.contractElementsGrid.verticalScrollPosition;
//put the elements from the contract into the array
collection
var tempElements:Array = new Array();
for each(var el:Element in modContract.elements)
{
tempElements.push(el);
}
this.contractElementsAC.source = tempElements;
//refresh the array collection now that we have given it a
new source
this.contractElementsAC.refresh();
//restore the scroll position
this.contractElementsGrid.validateNow();
this.contractElementsGrid.verticalScrollPosition = vScrollPos;
this.contractElementsGrid.invalidateDisplayList();
