Symphony.

I'm trying to filter a navigation data source by two values, a static and a dynamic one:

navigation + {$ds-sprache}

{$ds-sprache} returns the currently selected language (either deutsch or englisch in my case).

I was expecting that + will only return pages that have both types attached (navigation and deutsch/englisch). But it seems always return pages that match the first or the second value. Looking at datasource.navigation.php it seems like Symphony is checking, if is should join types by AND or OR.
