Take a GridPanel and place it in a border layout, center region. This grid has a PagingToolbar. If you make the window horizontally smaller so that the contents of the right-justified displayMsg collide with the buttons on the left, the text turns into a button. If you click on this button, it pops up a small menu that says "None".
Take the Paging Grid Example and place it in the center pane of a container with a border layout.
Steps to reproduce the problem:
Make the window horizontally smaller until the display message is truncated and turns into a button.
Click on the button.
The result that was expected:
Not sure... but perhaps a more advanced truncation algorithm?
At least the full text of the displayMsg should appear in the popup menu instead of "None"
One idea: Hovering over this button would also show the text from the displayMsg
The result that occurs instead:
Empty box with "none" appears
Screenshot or Video:
Three images are attached that show the progression of the problem as the window is constrained and the displayMsg disappears.
PagingToolbar is not compatible with toolbar overflow. As enableOverflow is now properly disabled by default in 3.1.1, you should no longer be seeing this behavior. We may add support for having an overflow in the paging toolbar in the future, although how it would look is still unknown.
