filter method for ODataTreeBinding

The "filter" method for ODataTreeBinding in current version of SAPUI5 is coded as follows:

    b.prototype.filter = function(f) {

        q.sap.log.warning("Filtering is currently not possible in the ODataTreeBinding");

        return this;

    };

The question refers only to OData model, because filtering works when the JSON model is used.

Any ideas how do you solve the problem of filtering in TreeTable control binded to OData model?

Thanks,
