Hi,

Just wondering if anyone knows if IsEmpty works for $VAR or if there is another way to check a VAR?

I have an on-going issue in Madnox that after a random amount of time VARs just start losing their value. A ticket (16634) has been opened a whlle ago on the issue. Basically the var used in a colordiffuse becomes blank / empty so panel backgrounds become transparent and windows then are unreadable as no background exists. Can be any window at any time!

So I was wondering if I can build in checks / work arounds just in case the issue can't or isn't resolved? i.e. display different background on !IsEmpty or IsEmpty?

I think StringCompare\IsEmpty is not supported in variables.
I tried it here in this case: http://forum.kodi.tv/showthread.php?tid=263337

Maybe something tricky Mike but what about placing a dummy invisible label containing the VAR also as label and a fallback with "EMPTY" text ? Give it a ID and check if the Control.GetLabel(ID) is "EMPTY" ? Not 100% sure but I have something in mind that make me think the fallback is returned by Control.GetLabel if label (VAR) is empty.

For "Text Var´s" I often use a value Fallback at the end of the VAR with a simple Text like xxx..
And use the VAR in a dummy invisible label with ID and stringcompare it with negation on xxx.
This works better. IsEmpty doesent work in some cases for me, or i use it more than one times,
so its easier in a hidden control.
