Description Paul Webster

2010-07-07 15:04:23 EDT

I had code that looked like:
MMenu menu = model.getMainMenu();
menu.setToBeRendered(false);
engine.removeGui(menu);
model.setMainMenu(null);

It generated an exception.

As a workaround I null out the field on dispose.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
