Error using custom field in weighting tree (both in QGIS2 and QGIS3) #470

Open ptormene opened 6 years ago

It happens when attempting to use a custom field but no field is available to save the calculated value. If, on the contrary, an available field exists, it is possible to select it, and it works.

TypeError: fieldNameIndex(self, str): argument 1 has unexpected type 'QPyNullVariant' 
Traceback (most recent call last):

We might keep the option to use a custom operator and, if no field is available, a new field could be created to store the composite index
