Hello,

I have a window (MWin) when I click on a button, it changes to an other view (MiniMWin).I want to save the pos of MiniMWindow on savestate, only problem is when the MiniMWin hasn't been used yet it causes a problem.

My code:


function OnPluginSaveState ()
 	SetVariable ("TopMiniWin", WindowInfo (MiniMWin, 11))
	SetVariable ("LeftMiniWin", WindowInfo (MiniMWin, 10))
end -- OnPluginSaveState


error :

[string "Plugin"]:383: bad argument #2 to 'SetVariable' (string expected, got nil)
stack traceback:
[C]: in function 'SetVariable'
[string "Plugin"]:383: in function <[string "Plugin"]:379>

I know why it's giving the error just not how to solve it proper.
What would be the way to solve this?

Hope this makes sense.

Why? Why not just save the position of the original window, which should exist, rather than a button which may never exist?
