Hi,
I am trying add attribute value as prefix to joined attributes, but I have not succeeded. @bo had quite similar problem Add parameter as prefix...
I have created attributes at main.
Then I expose those attributes at custom transformer
But I cant get prefix when I add Joiner
Goal is to have 1_REGISTRATIONDATE, 1_FORMERPARCELLOCUNITID and 2_REGISTRATIONDATE, 2_FORMERPARCELLOCUNITID on the second round and so on.

I'm assuming you want to use a custom transformer to loop through the join several times and add a prefix to the resulting attributes based on the loop counter, correct?
If you don't use a prefix in your Joiner but instead use a BulkAttributeRenamer inside your custom transformer it should work.

Correct.
I have tried that, but it didnt work. I also lost values.
I dont know which of there is correct way, but neither works.
+49I got it to work with an attribute. Here's my sample, maybe it's useful.
+49The table view won't accurately reflect this because it's a fixed schema, in your case not all attributes exist on all features. Does the main Feature Information panel show the correct values?
