Hi,
I just committed a patch that makes it a lot easier to mark invalid tabs in
popup windows for instance the new VM window. Before when you added a new tab
you would have to create a isXXXTabValid boolean in the model, and add a
propertyChangeEvent to that boolean. Then in the view you needed to listen to
changes in a giant if/else statement for all the different tabs in the view.
Then in your validation routine you would call setIsXXXTabValid(true/false) to
set the tab valid or invalid. Now all you have to do is the following. In your
validation routine call setTabValid(TabName, true/false). The TabName is an
enum that lists all known tabs. If you make a new tab that is not already
there, just add it.
There is no need to create/listen to property change events, as at the end of
the validation routine a validation complete event is called and this causes
some code to run to evaluate all the tab states at once, and it highlights all
invalid tabs at once. It also selects the first invalid tab and makes it
active. This should greatly improve the user experience as it is now evident
which tabs have problems and the first problem is active by default.
