no value in the attribute form if value missing in the value map

[j-lippmann]

hello
If there a value in an attribute table datafield which is not in value map, then the value not visible in the attribute form if i click the feature with the info tool.

tested with qgis 3.11 an 3.4

[elpaso]

I might be wrong but I think it's designed this way.
If the value is not in the map I guess it's not a valid value.
@m-kuhn what do you think?

If the value is not in the map I guess it's not a valid value.

the values that are not in the value map are supposed to show between parentheses. In my 3.4 installation it works are expected.

[m-kuhn]

Other widgets (e.g. relation reference) show (value) in this case to make sure data is not lost.

Anyway, is this a regression? I think it's always been working (or broken) like that.

I haven't tested master, but on the latest 3.4 works as expected.

@gioman did you test the attribute form too (the screenshot shows the attribute table)?

@m-kuhn you were right, in the feature form (both from identify or table) the value is not shown. Regression?

[m-kuhn]

Regression?

I don't think so. But annoying anyway.

Update: if i turn edit mode on, i can use the "picklist" and i can see/use the missed value in the value map. but the missed value do not appear in the attribute form , if the edit mode is off.

[elpaso]

I might have checked and fixed the editable scenario only. I'll check the read only.

[elpaso]

@j-lippmann I just tested on master with a layer that is not editable and I cannot reproduce the issue.

Can you please attach project and data so that I can test exactly your scenario?

[elpaso]

@j-lippmann I've just noticed that NULL was not handled correctly, I've added a few lines of code to handle that case in #37031

[elpaso]

@j-lippmann can you please check latest master and check if you can still reproduce the issue?

[j-lippmann]

@elpaso the issue is still present with this master:

I tested again and I cannot reproduce the issue on my dataset.

[j-lippmann]

hello @elpaso
do i have the correct code version?:

QGIS-Version
3.13.0-Master
QGIS-Codeversion
e81af2c

i have attached my little qgis testproject (qgis-project is inside of the gpkg). it would be kind, if you could test with this project.
thank you very much

value_list.zip

[gioman]

I tested again and I cannot reproduce the issue on my dataset.

@elpaso I just tested with @j-lippmann sample project (and also with one of mine) and I confirm that in the edit form a value that is not in the value map does not show by default in the combobox/dropdown:

value in the value map

value not in the value map

@j-lippmann It appears to be working as expected on QGIS 3.22.3. Did you come across this issue more recently?

No. I have tested today with 3.22.3 and it works as expected. No more issue...cool! Thanks
