    [CLOSED] Table in BorderLayout Problem.


    Hello. Sorry for not posting problem in one class but it would be just too much code and confusion.
    The problem is in table I've created. It's dissapearing when i minimize <-> maximize my window. Reproducable in gwt hosted mode browser and in firefox3 (dunno about other browser, i didn't tested. I hope You could manage to include this patch in beta2!

    You are not using containers and layouts properly.

    In your code you give the viewport 3 different layouts (FillLayout, FlowLayout, and BorderLayout).

    When using a BorderLayout you should not size the child components. That is the job of the layout.

    You should also avoid percentage based sizes in most cases. You are setting a width to 100%.

    Try taking a look at the explorer demo code so sample usage. Also, you can use Firebug with Firefox to inspect the DOM to see what is happening in you page.
