Resizing columns throws index out of bounds exception

XMLWordPrintable

    • Icon: Bug Bug
    • Resolution: Cannot Reproduce
    • Icon: Neutral Neutral
    • None
    • 6.2.5
    • content app, vaadin integration
    • None

      Reproduce

      • Open the Pages app.
      • Resize the Tags column
      • Check the log for the stack trace

      Expected
      No exception should be thrown.

      Actual
      While the resizing seems to work the effect in the UI looks a little off as well. Plus of course the exception.
