Description
Hi,
when opening an existing project using expressions or sql queries in Rule based classes or labels or feature subset, if expression cannot be evaluated, no warning is raised.
For example, the data field names have changed.
User have some empty classes, or totally empty classes or labels, and finding why can be long.
Having a soft warning would be sufficient. Something like "expression XXX on layer (labeling / style) could not be evaluated... please check"
Cheers
Régis
