I have an AdvancedDataGrid defined in my app. The width is explicitly specified, while the height is 100%. The width and minWidth values of the columns do not add up to a total greater than the grid width. I'm using the default skin, and it has a Hierarchical dataProvider.
When the tab with the grid becomes visible (there's a slight fade-in transition between tabs), the border for this AdvancedDataGrid is gone. As soon as I make a slight adjustment to the width of a column or populate the dataProvider with values (it's null until the user makes a few choices in the UI), the border appears.
Not even sure where to look for the solution. I have another grid on a second tab defined the same way and it works fine. I've tried making the column widths narrower and making the explicit grid width narrower to no avail.
