    Thanks Andrey,

    I am using what you propose for getting child context at session level
    chidContext= globalContext.createChildDataContext();. But I dont understand your sentence :
    >> it collapses to just calling one method.

    Do you mean using localObject to get object in globalContext ?

    objectInGlobalContext = (XXX) globalContext.localObject(myObjectInLocalContext.getObjectId(),myObjectInLocalContext);

    Thanks again for your help

    Pierre
