Search pools by member error when the server is member of a pool that has no relation with vip

When we have a server that is member of a pool that hasn't a entry in "VipPortToPool" (so the pool is not correlated to any vip - ie, with any instance from table RequisicaoVips), the API is unable to display anything when searching for pools that a server is member from (note that the API knows it is a member of at least one pool, but is unable to list it/them). Error shown: "unable to access data source/Falha ao acessar a fonte de dados".
