Hi,
    I am now struggling on handling validation exception when the user
close the internal frame.  Please give me a hand.
    My situation is I have many internal frames using one genernal close

button on the toolbar which set the internal frames invisible upon
clicking.  However, the textfields in some of the internal frames use
focus lost for validation (show Dialog message for validation
exception).
    In that case, if the close button is clicked when the focus is on a
textfield having focus lost validation and the validtion exception
throws.  The internal frame is hidden, but then the Dialog message shown

due to focus lost validation.
    So, how to make the Dialog message show before the internal frame is

hidden.
    Or, simply make the Dialog message never show when close button is
clicked.

    Any suggestion or hint are appreciated.

Thanks,
Keith.....
