that is not a good way to use gwt, as you did not abstract yourself from html, but is just writing “html” in java.

what you could do is instead define two more widgets – one widget for the collapsed state view, and another for the open state view. how you implement these widgets is up to you, but i would just have another table in there.

then, in each cell of the flex-table you would add in the correct widget when the click happens.

that way, you dont get bogged down in the click handler with table manipulation code.
