Edit mode on remote portlet

Hi all,
i deploy a portlet (JSR 168) on Producer (Pluto with wsrp4j), i consume this
portlet with uPortla and Liferay.
When on consumer i go on edit mode, when i finish the operation of
configuration, the portlet dosn't go on view mode?
At producer side all functioning, but on consumer not.
