Hi Felix, I can reproduce it. Problem is that the generated 'xml' file is not generated correctly. The parameter 'vlen' should be written as '$vlen' in the xml files source/sink section but it is written as 'vlen'. Thus 'vlen' is treated as the value. Happens with 'v3.7.2-11-g3b27cc47'. I don't know how to fix it though.
