Hi Sandro

Thanks for you help. I was thinking about the same solution as you have 
mentioned. The only problem is, is that I the call from the event will happen 
at a different time than my call to a trigger method on the client. If there is 
no way of retrieving a value, then I will be forced to search for a different 
solution in creating the image

Hi Paul,

I'm not 100% sure but as much as I know, this is not possible to do, because of 
the asynchronism between the server and client.

However to address this problem you normally would do something like that:

Precondition:
1. create an action listener on the server side.

Procedure:
1. server calls method on client side
2. client side method creates an image and sends it back to the server. This 
happens through the trigger of the server side action of the previous created 
action listener.
3. the action listener on server side gets notified and receives the image. Now 
you can do whatever you want to..

Hope this helps!
Sandro
