Filter cellerator by value node

Hi,

recently I need to realize a table view (using cellerator tag) which displays as list of opportunities. I chose BTAdminH as table context node type and added a value node "completeness_status". This value node field is filled in DO_INIT_CONTEXT and reflects if some necessary partner functions in the opportunity have been filled. The completeness_status field is of CHAR1 and has three characteristics: 3 = complete, 2 = partially complete; 1 = incomplete.

I like to create a button on top o the table view where I can toggle between displaying all entries and only incomplete and partially complete entries. I tried to realize this by iterator method FILTER_BY_PROPERTY on the context nodes' collection wrapper.

Unfortunately I realized that filtering this way is only possible on model node attributes but not und value attributes.

Can anybody can give me a hint how to filter a table view by a value attribute?

Thanks and best regards,

Markus
