How to find client side caller information (content_id) in a server side java action

Is there a way to find the client window (caller) content_id in custom java action? I try to display a message only to the caller window. Currently a message object is associated with a user. When a msg is send by the server, it updated the msg object. The widget is subscribed to updates and displays the message. This results that message is shown on every tab and popup. When it is possible to find the caller (content_id) in a java action the message object can have an attribute to address the message to one specific window (widget). How can I find the caller details on the server side? Thank you

The Mendix client does not include such information with requests to the server. So the answer is no; you cannot determine which client component performed the request on the server side.
