Redirect to another portlet within portlet

Hello Colleagues,

Please help.

I have two Vaadin Portlets - TaskListPortlet and TaskPortlet

I place TaskListPortlet on page and I need to redirect from TaskListPortlet to TaskPortlet
within the same place on page.

How to do that?

Portlet 2.0
Vaadin 6.2.3
Liferay Portal 5.2.3
GlassFish 2.1.1

Thank you in advance.

I don’t know what exactly you mean by redirecting but for example you could use public render parameters to pass the information about selected task to other portlet if you have them on the same page.
