[jboss-user] [JBossCache] - ClassCastException: java.util.TreeSet: while trying to attac

[bahata]

Hi
I am getting the exception ClassCastException: java.util.TreeSet , for 
the code "cache.attach("datamodel",dataModel);" I am using JBossCache 'Habanero' 2.0.0.GA. Kindly help! It is a blocking condition for our project!

-----------------------------------------------------------------------------------
Code:
	String configFile = "resource/replSync-service.xml";
	        PojoCache cache = PojoCacheFactory.createCache(configFile);
	        
	        cache.start();
			
	        Object obj=cache.find("datamodel");
	        DataModel dataModel;
	        if(obj!=null)
	        {
	        	dataModel=(DataModel) obj;
	        }
	        else
	        {
	        dataModel= new DataModel();
			DatabaseController.loadFromDatabase(dataModel, loadDates);
        	cache.attach("datamodel",dataModel);
	        }
