Issue

• Dynamic group creation error

• Dynamic group definition fails to save with the following error:

  There was a problem calculating the results: java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: could not locate named parameter [arg1]
  

• Using two or more traits in a DynaGroup definition expression results in the following exception:
