It seems there is a problem with nested joins.
By nested joins, I mean layer A is joined to B which itself is joined to c, then D etc.
What I expected when I open the attribute table of layer A is to get all the attributes.
They would named in QGIS:
A_attrs | A_B_attrs | A_B_C_attrs | A_B_C_D_attrs
I set up a small project to test this.
In my setup, only the attributes of the first join layer are shown (B in A, C in B, D in C).
But, when trying this with Andreas yesterday, all attributes column where shown, but some were filled with NULL values.
