[xwiki-devs] Running groovy code in the background

Hello developers, I've been experimenting a little bit into running things in the background on our xwiki 3.5: as part of a velocity delivered page, I am calling groovy code. That code launches a thread in the background which runs for 1000 seconds checking if it can: - use the context's toString - call context.getContext() - use the xwiki object that was passed around My current conclusion is that context.getContext() fails (with an NPE trying to check programming rights) but others work. Is this the intended behavior? Is there a way for me to get another context to run in the background? thanks in advance Paul
