[hibernate-dev] Major issue with Hibernate Filters

[Alex Bacon]

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
