I added a fix for this, though I am not sure if that is the correct fix or only
a work-around:
I inserted a line
foreignTypes = Array.from(new Set(foreignTypes)); // remove duplicates
into function typeRegistrarCommands() in qml.js of the Qt module provider
template. This removed the duplicates from the array and the
warnings are gone.
Is that the correct solution? Should I open an issue for this?
Regards, Jochen
