log snippet

Description of problem:

When calculating a dynamic group definition with more than one trait in the conditions a hibernate exception occurs. No group members are found.


Version-Release number of selected component (if applicable):
JON 2.4
EAP Plugins
SOAP Plugins
EWS Plugins
JDK 1.6 U23

Steps to Reproduce:
1. Create a new Group Definition
2. Enter the following as the conditions

resource.grandParent.trait[Trait.hostname].contains = stage
resource.parent.type.plugin = JBossAS5
resource.type.name = Web Application (WAR)
resource.trait[contextRoot] = jmx-console

Note: just using the jmx-console as an example, it won't matter what the context root is (unless it is blank because / as context root is not handled and throws the following syntax error:

Syntax error in your group definition: Expression must be in one of the follow forms: 'groupBy condition', 'condition = value', 'empty condition', 'not empty condition 

)

3. Save group
4. Calculate group members
  
Actual results:
In the UI:
There was a problem calculating the results: java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: could not locate named parameter [arg2] 

In the Log: 
ERROR [org.rhq.enterprise.server.resource.group.definition.GroupDefinitionManagerBean] Error recalculating DynaGroups for GroupDefinition[id=10011]
javax.ejb.EJBException: java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: could not locate named parameter [arg2]

see attached for relevant stack trace


Expected results:
Find all deployed jmx-console Web Applications for JBossAS 5 profiles on servers with "stage" in the hostname

Additional info:
It will find all Web Applications for JBossAS 5 profiles on servers with "stage" in the hostname if I remove the last line - so I think the condition is valid.

This also occurs when other group definitions with more than one trait in the conditions.
