QField support for document management system

[jpdupuy]

Hello

I have installed QGIS 3.20 and the Document Management System plugin 0.9.

The DMS plugin is fully functional on QGIS Desktop, But it is not functional with the mobile application QFIELD Dev (master-dev) e60e70.

Based onQGIS Desktop 3.20 I could declare the polymorphic relations :

I also could define the layer properties on : od_etat_arbre

And finally I could link the document to a feature. I can display the JPG document 👍

However with QFIELD Dev, I do not see the image I have linked to the feature.
Entering the Edit Mode, I cannot add a new image (error message : cannot add a child object, the parent primary key is not available)

You can review my qgs project : ARB_DMS (I have set it to edit mode in QFIELDCLOUD)
