ClassCastException when using a Tinkerpop Graph imported from a GraphML file

[Salvatore Piccione]

Hello,

I get a ClassCastException when I try to add an edge to a vertex that was created by importing a GraphML file through Tinkerpop Blueprints utility class (GraphMLReader). This exception is thrown using both orient-graphed-1.0rc8 and orient-1.0rc9-SNAPSHOT in the following combinations:

• orient-graphed-1.0rc8 and blueprint-orient-graph 1.1
• orient-graphed-1.0rc8 and blueprint-orient-graph 1.2
• orient-1.0rc9-SNAPSHOT and orientdb-blueprints 1.2o-SNAPSHOT
  
• orient-1.0rc9-SNAPSHOT and blueprint-orient-graph 1.2

That exception was not thrown using orient-graphed-1.0rc7 and blueprint-orient-graph 1.1.
A test case that reproduces the failure is available at https://gist.github.com/2021474 while the complete stack trace is available at https://gist.github.com/1540820.

HTH,

Salvatore

Hi Salvatore,

your error is reproducible and the cause seems to be the dropDatabase() that in remote leave the connection status dirty. I'm working on it.
