New Post: SPCascadeDropdowns and filter in parentList

Is there a way to properly filter the parentList? I had the impression I could use the CAMLqueryoptions for that (because the documentation says: "This option can be used to specify additional options for retrieval from the sourceList")

So I added:

CAMLQueryOptions: "<Query><Where><Eq><FieldRef Name=\"Active\" /><Value Type=\"Text\">1</Value></Eq></Where></Query>"

Well.. I didn't work =) any advises?
