#78 MultiSplitDockableContainer IllegalArgumentException
When the toolWindowManager has got many visible toolwindows (just the title bar is visible for each) and we try to hide a tool by clicking on the X button, it crashes because of and IllegalArgumentException in the class: MultiSplitDockableContainer, method: removeDockable(Dockable dockable). The Component component = multiSplitPane.getMultiSplitLayout().getChildMap().get(leafKey); returns a null component, but in fact the component is still there (probably it's not visible).
Discussion
Hi Albu,
do you have a stacktrace for it? I need more information on the scenario.
Best,
./angelo
The line numbers maybe are not right because i made a format on the source code.
To help your work, i attached the file too.

Hi Albu,
the class you sent me is old. Please update to the latest revision and verify again if the problem persists.
Best,
