ORecordLazySet cannot be cast to com.orientechnologies.orient.core.db.record.OIdentifiable

[Rob Lally]

Hi folks,

I've found another problem with:
Orient RC-5
OSX - 10.7.1
JDK version 1.6.0_26

When executing the query you can see in the log below, we get a class cast exception.

Any suggestions?

Hi,

did you created indexes with previous releases? If yes just rebuild the indexes from console:

> rebuild indexes *

I'm seeing the same error running select out() from vector1. 

the configuration is vector1(linkbag) from edge1(linkset) to vector2(linkbag). 

It works fine with vector1(linkbag) from edge1(link) to vector2(linkbag). 

Version 2.05

I think I misunderstood what a linkset was. Now I see its a collection of links. thanks
