I have a tab navigator with 2 tabs. Each contains a Canvas,
each canvas has many childern including a DataGrid.
The DataGrid in the first tab, dg1, I can hide the headers no
problem with "dg1.showHeaders = false", as always.
However, the grid in the
second tab (canvas), dg2, does not respond to
"dg2.showHeaders = false". Then headers show up anyway, and an
error occurs in the trace output: Error #1009: Cannot access a
property or method of a null object reference.
Why is this? How do I hide the headers in this second
