Subject [jira] Commented: (CXF-3022) Integrating Spring 3 + GenericDAO (Don't repeat the DAO!) + CXF JAX-RS (JAXB Databinding) with a Generic Service Interface
Date Thu, 07 Oct 2010 17:11:31 GMT

    [ https://issues.apache.org/jira/browse/CXF-3022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12918976#action_12918976
] 

Sergey Beryozkin commented on CXF-3022:
---------------------------------------

I haven't managed to fix it so far, I'm afraid I'll have to investigate after the release.

What I've found so far  though is that there's no any concrete type information associated
with T.
In all my tests I have static information available in concrete implementations extending
generic classes 
or implementing generic interfaces.

This is exactly the reason why I suspect you have methods with PK parameters invoked successfully.
Because PK extends Long
and this is what CXF manages to get to...

Can you please for the sake of the test, have 

<T extends MobilityUser, PK extends Long> ?

lets see if it works and if yes then we can try to figure out how to fix it...
