Original Redmine Issue: 20455
Affected QGIS version: 3.4.1
Redmine category:forms

I have made a project with a point layer and two lookup tables: Group and Subgroup in the Subgroup tabel is listed 'group', 'subgroup' and 'label'

In the Layer properties >Attriute Form > Widget type >Value Relation I have made settings to lookup in the 'Group' lookup and the sub group.
That works fine. The first group and subgroup is shown. If I choose a new Group the new subgroup item are shown.
But the 'label' is not set correct. All the features in the table are shown.

If I choose a new group and subgroup the label are set - but only if the subgroup consist of more than one item.

I have made a video https://www.screencast.com/t/mKEjlmfBIxFK

I can't see the screencast (no flash player here since a long time).

Also, if you could attach a sample project and data, that would be perfect.

Hi Lene,

I may have a fix for this issue, would you be able to test a windows build? (I can quickly package and send you a test build but without python support).

Here is the windows test build, no need to install, just unzip somewhere and run qgis.exe, remove the folder to uninstall.

http://www.itopen.it/bulk/qgis-mxe-release-2018-11-12-15-03-01.zip

What to test:

• the original project attached to this ticket
• how does it work with new and existing features
