Placeholder in databasejoin element

Hey there,

I build a form with 2 elements.
First element is a Calc Element (returns an id from somewhere).
Second element is a database join to an existing table.
The databasejoin should be rendered as checkbboxes.

Now I want to filter the results from the database join via where (where {thistable}.id = ...).
This also works fine as long as I use a hardcoded value for the Where clause.
BUT I want to use the calc element placeholder and this doesn´t work.
Code:
WHERE {thistable}.id= '{registered_teams___comp_id}'

Is there a chance to use placeholder with Databasejoin?

ok, it seems the placeholder is just empty.
now I looking for a solution to calculate the needed value before the dbjoin asked for it.

any ideas?
