Joomla 3.2 modify com_content / category query / add a filter

Question

I want to modify com_content / category to fit a custom database /w some additional fields (for compatibility-reasons with modified com_content from J1.5).

The function _buildContentWhere, that was available in Joomla 1.5 in components/com_content/models/category.php is gone.

I can't figure out, where I can modify the query to put an additional WHERE-clause now. I just want to list items in this category that fit a special condition (passed as GET-Param).

Answer 1

The items are now retrieved querying another model, com_content/models/articles

The query is built in the getListQuery() method.
