SchemaViolationException from Groovy class [titan09 branch]

[Jordi Chacón]

Hi!

I have written a very small Groovy application that queries a TitanGraph.

I am using the titan09 branch from a couple of days ago (52ce310b24fa0625760d47a92a629cc4bbe86432).

This is an extract of my Groovy class:

TitanGraph tg = TitanFactory.build().set('storage.backend','inmemory').open()

def mgmt = tg.openManagement()

mgmt.makePropertyKey('important').dataType(Boolean.class).cardinality(Cardinality.SINGLE).make()

mgmt.makeVertexLabel('person').make()

mgmt.commit()

Graph g = tg

def person = g.addVertex('person')

person.property('important', true)   // Exception happens here

And this is the exception I get when I run the application:

com.thinkaurelius.titan.core.SchemaViolationException: Value [true] is not an instance of the expected data type for property key [important] and cannot be converted. Expected: boolean, found: class java.lang.Boolean

        at com.thinkaurelius.titan.graphdb.transaction.StandardTitanTx.verifyAttribute(StandardTitanTx.java:577)

        at com.thinkaurelius.titan.graphdb.transaction.StandardTitanTx.addPropertyInternal(StandardTitanTx.java:721)

        at com.thinkaurelius.titan.graphdb.transaction.StandardTitanTx.addProperty(StandardTitanTx.java:706)

        at com.thinkaurelius.titan.graphdb.vertices.AbstractVertex.property(AbstractVertex.java:139)

I have also tried to cast the boolean:

person.property(IMPORTANT, (boolean) true)

But the same error happens.

This also happens with the Long data type: I have a property called 'user_id' of type Long which I use in some vertices to store the id of the user vertex. This is the error I get then:

Value [256] is not an instance of the expected data type for property key [user_id] and cannot be converted. Expected: long, found: class java.lang.Long

Is this a bug or am I doing something wrong?

Any help is greatly appreciated.

Thanks!!

We will release a Titan09M2 pretty soon. Can you check then. The current development branch is not stable enough to assess such issues against.

Thanks,

Matthias

Thank you for your reply Matthias!

Will check again when you make that release and let you know if it's fixed.
