Why can't I use this expression in a GO?

[Mats_Knutsson]

I have an expression resulting in a string value valid or non_valid. I can't use it in my GO though. I can't even see it when adding properties to the GO rule. Why so?

It seems only Expressions that only use the "general parameters" can be evaluated in a GO.

Smells like a bug (by design) to me. At least it should be available when we set the "element type" in the GO to the right type...

Some parameters (and expression-based Properties using them) are not available as Graphic Override criteria:

Thanks Lazlo!

I'd like to ask GS if it is my job to accidentally find these "not available" properties/parameters?

Probably not, but if you do, it is appreciated.
