[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2116) Query.isAnyParameterDirty is true for query without parameters

[Petr Kolesnikov (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-2116?page=all ]

Petr Kolesnikov closed JBSEAM-2116.
-----------------------------------

    Resolution: Done

fortunately not so bad in reality -), my fault 
Query has an empty list of ParameterValues (after population!!!) for slqs without parameters.

The design point still remains is that Query loses a ref to DataModel if JSF get it before the Query population that is i think usually the case.

1. Query.getDataModel()
2. Model.getRowCount() that usually  results in Query.getResultCount() and Query.dataModel==null

In my case Query.getDataModel() gets called in apply values(do not know why) and rerender phases. This creates two DataModel objects for one request.
