Error in filter-def condition attribute definition caused by trim sql function
------------------------------------------------------------------------------

                 Key: HHH-5970
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5970
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.6.0
            Reporter: Tomáš Šafařík


I have encountered an error that in filter-def definition in condition attribute is not possible to use SQL function trim with expression. 
For example this definition: <filter-def name="concatInTrim" condition="TRIM(CONCAT(TITLE,TITLE)) IS NOT NULL" /> causes this error:

I think, that this problem is caused by function org.hibernate.sql.Template.renderWhereStringTemplate(), that doesn't take into account possibility of expression in trim function argument.
I think that this problem is related to http://opensource.atlassian.com/projects/hibernate/browse/HHH-5676?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#issue-tabs.
In attachment is test case based on Hibernate tutorial (hbm.xml Tutorial).
