<p>Hi Ale,</p>
<p>That would explain it ;-)</p>
<p>I also tried various other combinations, like</p>
<p>with @current_parent_feature, @feature, etc. - but haven't found a working version ...</p>
<p>I might try with a variable ;-) I got the variable filter version working in another project. But that involved Python ...</p>
