Providing liferay user id into orbeon form runner generated xml

Question

I make portal based on Liferay, which has funcionality associated with Orbeon. I run Orbeon form runner inside html frame and I want to insert some extra data like Liferay-User-Id into xml generated by filled form. Is there some possibility to make that or other idea that helps me provide, user's id who filled form, to database?

regards

Since Orbeon Forms 4.4, the Liferay proxy portlet allows you to propagate user information as headers. This is possible because the portlet has access to Liferay user information.

From within an iframe, it's a different story. If you manage to set URL parameters, then you can retrieve them from your form with the xxf:get-request-parameter() function.
