I don't know, what the field o_id is for, but there is at least one mistake in the xpdo-schema.
there is o_id two times defined.
do you get anything with this snippet-call:
[[migxLoopCollection? &packageName=`bir` &classname=`birCourt` &limit=`10` ]]
this snippet-call shows nothing? Do you see any items for Courts in the CMP (the Custom Manager Page)?
