Description

In QGIS 2.18.8 it is not possible in the expression editor (Select by Expresssion / FieldCalculatur) to display the list of fields under "Fields and Values".There is only the entry NULL. The use of the expression editor is now very difficult.

Best regards Claas

  • Operating System deleted (Windows 7 / Linux Ubuntu 16.04)
  • Category changed from Field calculator to Expressions

This regression was introduced since 2185d42dbcd81be4e45498cdacd82ee74fcb59c7 in order to fix the issue #15633.
I think that commit should be reverted and then finding a better fix for the processing field calculator.
Thinking to some solution for the processing field calculator, I guess we need to reset/remove scope from context when switching between layers.

Anyway, here I done a patch if we want leave things like they are now, without reverting the above commit.

9a19a5fc587e0764afee91c038cede04e4602fcc is the fix - it just needs backporting
