How to correctly uninitialized a MPxNode?

[Anonymous]

Hi,

I am using a MPxNode to store my attributes and everything works fine but when I unload my plugin, a warning is trigger. I looked in the documentation but I cant find a way to remove correctly the MPxNode.

Do you know which method I need to call to clean my MPxNode properly?

After deleting a node, it still exists in the undo queue.  You need to run "flushUndo" before you can unload their plugins.
