I'm trying to conditionally display a field in the "Advanced Search" of a custom application. Associated the sigoption to the field, added condition and provided conditional properties but the sigoption doesn't seem to be evaluated. Clearly its not able to identify a data source.

So I've added a datasrc with the object name, the sigoption did work after this but it broke the search functionality of the field.

I was wondering if I missed something or is there no way to have conditional sigoption in Advanced Search?
