[hibernate-dev] RE: Major issue with Hibernate Filters

You need to point me to where we ever created an example of filter usage
"in order to achieve uniqueness".  That is expressly *not* a usage of
filters; filters by definition cannot change the multiplicity of an
association.

Subject: Major issue with Hibernate Filters

Hibernate developers,

I'm afraid the forums had nothing about this issue - and I believe I
have found the bit of Hibernate coding causing the problem:

I have spent the last few weeks trying to get the Filters to work as per
the example in the Hibernate reference manual - the problem is that
filters are only currently applied for queries - they are not applied
when lazy loading entities - this causes major errors when using the
historical filters as per your example that need the filters in order to
achieve uniqueness.  (I cannot realistically eager load everything in
the database!

Here is the bit of code from AbstractEntityLoader that appears to be
causing the problem:


public void processFilters(String sql, SessionImplementor session) {
               
                if ( session.getEnabledFilters().size()==0 ||
sql.indexOf(ParserHelper.HQL_VARIABLE_PREFIX)<0 ) {
                        // HELLA IMPORTANT OPTIMIZATION!!!
                        processedPositionalParameterValues =
getPositionalParameterValues();
                        processedPositionalParameterTypes =
getPositionalParameterTypes();
                        processedSQL = sql;
                }
                else {
                       
Do you agree this is an issue - and if so - I take it I should raise it
as a JIRA issue.  If not - can you suggest a workaround?

Alex
