[overlord-issues] [JBoss JIRA] (SRAMP-202) The not() function doesn't quite work with relationships

The not() function doesn't quite work with relationships -------------------------------------------------------- Key: SRAMP-202 URL: https://issues.jboss.org/browse/SRAMP-202 Project: S-RAMP Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Eric Wittmann Assignee: Eric Wittmann Priority: Minor Fix For: 0.4.0 - API Management The not() function works well with properties, but not quite with relationships. An example of what doesn't work: /s-ramp/wsdl/Part[not(element)] That should return all Parts that do *not* have an element relationship. Since relationships are found by doing a JOIN, it's actually tricky to invert. Right now I think the query engine will produce something that would return all Parts that have some *other* relationship - but it won't return Parts without any relationships at all. I'm not sure how to do the latter other than by using an IN with a subquery (which is supported by ModeShape but is non-standard).
