I have some suspicions about text rendering and initialization, but I
haven't used the grid much yet. Please create a bug to keep track of
this issue.
One clue: it is usually helpful to specify a <text> object's width.
In this case width="${parent.width}" would help. <text>'s default
width is small.
And: look at dataControlsVisibility. For debugging, it is useful to
give databound text objects an initial value of "..." or "xxx" so you
can see what it looks like even if there's databinding problems.
Hope this helps.
