"[Solved] Use of macro within loop parameter deletes all attributes"
Contributor II
Dear all,
I discovered that it is not possible to use "generate macro" within in the "loop parameter" operator. In that case the process shows no output at all.
Please see also my post "Missing output of Loop Parameters operator" regarding a strange outcome with this parameter.

if you have a look at the process log, you will see the following message: That, means, that the Generate Macro operator had an error, and the loop iterations did not complete.
The reason is that you currently can't use the param() function in Generate Macro.

Ahh... the log... after seeing the solution I am always wondering why I haven't seen it before...
Thanks!
