Issues in 3.1

[dan-kez]

Thanks for creating this example! I'm hoping to structure my trigger off of this template. However in neo4j 3.1 I'm receiving the following error:

Any thoughts on this?

Did you update the POM to the version you are using?
https://github.com/maxdemarzi/neo_listens/blob/master/pom.xml#L12

Which version specifically did you try?

[dan-kez]

I hadn't. I am using version 3.1.0-BETA1

I updated it and am now getting the following compilation errors:

Try the latest version.

Thank you so much! It's running now.

I'm only seeing the following 3 lines in the console when running through the example:

CREATE (max:User {name:"Max"}) RETURN max;

CREATE (al:Suspect {name:"Al Capone"}) RETURN al;

MATCH (max:User),(al:Suspect)
WHERE max.name = "Max" AND al.name = "Al Capone"
CREATE (max)-[r:KNOWS]->(al)
RETURN r;

CREATE (monica:User {name:"Monica"}) RETURN monica;

MATCH (max:User),(monica:User)
WHERE max.name = "Max" AND monica.name = "Monica"
CREATE (max)-[r:KNOWS]->(monica)
RETURN r;

MATCH (monica:User)
WHERE monica.name = "Monica"
SET monica :Suspect
RETURN monica;

A new Suspect has been created!
A new direct relationship to a Suspect has been created!
A new indirect relationship to a Suspect has been created!

Not a big deal as at least the frame work is there to build off of but I figured I'd post the issue here.
