The sample that I posted for you is using a HierarchicalData as the
dataProvider so there is some difference there. But, it still seems to
me like you are only missing an invalidate since your data shows up on a
column resize. To me that sounds like a missing
invalidateDisplayList(). I did notice a bug in JIRA re:
GroupingCollection and changes to underlying ArrayCollection a while
back... you might have a look there.

Ah,
I should have added that we are using a GroupingCollection rather
