Hi.

I'm setting parameter on the fly in my operator and I'm using setString() method which takes

CH_StringMeaning meaning

as a second argument.

I can extract this from my parameter PRM_Default and it looks that it works, but I'm curious what is this?

Thanks.

EDIT. It looks that I explained this mysef some time ago => http://forums.odforce.net/topic/19227-determine-if-parameter-has-expression/ [forums.odforce.net] <=, so I suppose it's needed to inform parameter what type of value we are setting, is it simple string, expression etc., right?

EDIT2. So how to set expression with this method on the label column?
This:

setString(“npoint(opinputpath(\”.\“, 0))”, CH_OLD_EXPRESSION, mylabelname.getToken(), 0, 0);

doesn't work and I get nothing on the label.
