I updated both Capella version (to 7.0.1) and M2Doc version to 4.0.0
It seems I was successfully able to migrate my old project to the new version (right click on Project folder in the Project explorer, then Migration->Migrate Project toward current version).
I also installed RP and M2doc add-ons (M2doc version 4.0.0), but it seems in no way I am able to set the M2doc variable. This is what I get from the docx template properties (empty list of variable names)
And also Load resource from the template wizard will have no effect (similarly to what happens in this thread: Creating Variables for Imported Templates with M2Doc)
I tried adding also all nsURIs but seems with no effects.
Do you have any suggestions?
Thanks!
For completeness, this is the list of sw installed within Capella
