labelExpression CONCAT NULL fields

Question asked by rodrigo.felga on Jun 5, 2018

I'm labeling a layer dinamicaly with 2 fields selcted by user. I create a labelExpression like that:

 

[FIELD1] CONCAT [FIELD2]

 

When the user selects 2 required fields the labeling works great. When the user selects 1 required field and 1 not required field the label don't show for all features. I think because FIELD2 in the second case has null values.

 

Any help will be apreciated.
