2.7.2_01 suddenly some queries do only have 1 result even there are more results (you can use the database that you have from #308):
this query gives 1 result even there are a lot more:
select o from ObjectNode o where o.classIdentifier = '(OP)' and o.state = 98 and o.type = 0 and o.parentNode.classIdentifier = '(XX)'
if you take away the last condition you can see a lot of fitting results, a number of them fit with the complete condition
