Transaction in view state exception [DATAGRAPH-37]

[spring-projects-issues]

Stefan Ollinger opened DATAGRAPH-37 and commented

When using Transaction in view with the Scalate template engine and SpringSource tc Server Developer Edition v2.1 i get an exception when trying to fetch a 1:n property from inside the view.
This occurs only if "Enable gathering of metrics" is enabled in the SpringSource Server configuration. When disabled, there is no exception.

The issue seems to be related to this commit: http://git.springsource.org/spring-data/datastore-cross-store/commit/5379ba04a227621d0b6bee30b3fef2468249f0c2

This is the strack trace:
