> {quote}Hello, I am trying to test some custom python processors with nifi
> 2.0.0-M1
> It works fine except when I try to add custom relationships to it (other than
> the default success, failure and original).
> Here's what I am trying:
> {code:java}
> self.matched = Relationship("matched", "flowfiles having a match with
> the regex")
> self.unmatched = Relationship("unmatched", "flowfiles not having any
> match with regex")
> self.failure = Relationship("failure", "flowfiles for which process
> errored while matching")
> self.relationships = {self.matched, self.unmatched, self.failure}
> {code}
> I get py4j complaining about AttributeError: 'set' object has no attribute
> '_get_object_id'
> which seems like the auto conversion of Python to java container is not
> happening for "Relationship" class. Any idea what could be wrong here?
> {quote}
> The problem appears to be that Relationships created are of type
> {{nifiapi.Relationship}} but that is being sent back to the Java side without
> being converted into a {{org.apache.nifi.processor.Relationship}}
