portal navigation

Hi everyone. I am creating an application in which I have organized the content in the following way. i have 3 iviews , in 3 seperate pages within one workset. I have to enable communication between them, meaning that an event on one iview/page forces the display of another page.

I would like to create an event and fire it on the other component, and for that component to take over the display. i have examined the INode and the IPortalNode, but do not understand how to get the INode of the other component.

I have seen IComponentNode.createComponentNode(java.lang.String name,IPortalComponentContext context)

but I do not wish to CREATE and node, I wish to get it so that I can fire an event on it.

Can anyone help?

Thanks in advance,

Mariana
