Do transactions work at all with Orion?

[Robert Hargreaves]

Dear All,

I am using Orion 0.9.1.
I have a method in a Sesion bean with transaction attribute set to 

<trans-attribute>RequiresNew</trans-attribute>

The conatiner manages the transactions .The method looks like this:

public void addUnitAndComponents(BusinessUnitProps props,
                                                HashMap compToDateRa) throws
RemoteException{
    // first create the new unit and then for each item
    // in the hashmap add the component
    // The HashMap contains BusinessComponent : Date []
        
        try{
        BusinessUnit unit = buHome.create(props);
        Iterator iter = compToDateRa.keySet().iterator();
        while(iter.hasNext()){
            BusinessComponent component = (BusinessComponent)iter.next();
            java.util.Date [] dateRa = (java.util.Date
[])compToDateRa.get(component);
            unit.addComponent(component, dateRa);
        }
    }catch(Exception e){
                throw new RemoteException(e.toString());}
   }

I get an exception thrown at 

unit.addComponent(component, dateRa);

so therefore I expect the call to buHome.create(props) (which creates an
entity bean) to be rolled back. But it isn't. 

This looks very similar to

to which there was no reponse at all.

Is this a bug?
