Hi Greg,
if i add this
whatIsThisMenuItem.setEnabled(false);
after the line
whatIsThisMenuItem.setAction(new Action() {
...
});
at runtime I get this exception:
java.lang.IllegalArgumentException: Button and action enabled states are not
consistent.

note that in my case in my contextual menu now I have added other items (one
before this item, and another after, just for example) , so I don't know it
it's good to have this exception.
But in any case I think that the issue is the following:
if I add the same line but just before the setAction, i get no exception,
and the related item is selectable and the action is executed ...
I see that in the
public void perform(Component source) {
source is the Menu.Item, but as inspected by the debugger it has enabled =
true (and that's strange) ... and probably should be fixed, and the caller
of perform should call it only if source is enabled, ok ?
Than as a workaround I suggest to check if source is enabled, otherwise do
nothing (and maybe close the context menu).
What do you think ?
Bye,
Sandro
