i've tried to use the loop attribute operator to group some attributes.... but i always get the error The attribute 'loop_attribute' is missing in the input example set. Do i have to generate a new attribute first or are there other reasons ?

    Greetings Viktor,

    Welcome also to this house of shame, where we pretend that meaning has meaning  8) . Take the meaning of 'Problem'...

    You can see attribute looping at work, without problems, here,2107.msg8303.html#msg8303, so it is possible!

    It is however the case that if input ports have type checking constraints they can deliver warnings in the 'Problems' view when those constraints cannot satisfied by the metadata. Sometimes these can be ignored, because the constraints are met at runtime.

    And of course sometimes the code is just crap  :o

    So why not copy your XML and post it here ( mark it as code with the ' # ' button for a more enthusiastic response !)?
