Previously we used a small workaround for a problem we encountered with
component manager as follows,
In Utils.prepareContext() method we had a problem where the component
manager is null ... so we did,
ComponentManager componentManager =
(ComponentManager)
engine_context.getAttribute(ComponentManager.class.getName());
+ if(null != componentManager) {
+ context.put(ComponentManager.class.getName(), componentManager);
+ }
This worked fine untill recently. But I think now we have to handle this
issue. The main problem is,
ComponentManager componentManager =
(ComponentManager)
engine_context.getAttribute(ComponentManager.class.getName());
Here, componentManager becomes null. What could be the reason for this ?
Thanks a lot.

PS : Previously vincent said not to use this workaround but we used it since
it worked.
