WebDynpro iViews and Portal Eventing

Question

Hi All,
I am planning to prepare a proof of concept with following requirements.Can you please give me hints and resources to prepare this in 2 days?
1)Interaction between iViews using EP eventing.
2)Exploring how and what kind of data can be passed from one iView to the another (String , Java Objects etc)
3)Keeping track of various events of EP especially finding out if we can track when the user session is invalidated by the Portal so that we can free objects from memory.
4)The sample code should have 2 to 3 iViews interacting with each other and passing data.With detailed description of each steps from coding till deployment to the EP.
Thanks & Regards,

Hi Noaman,
You can use EPCM for eventing between iviews in portal. Also we can use the same for communication between Webdynpro and EP applications.
You can pass parameters using client data bag. The code for sender ....
var an='Hello';
EPCM.storeClientData("urn:namesapce","key",an);
EPCM.raiseEvent("urn:namesapce","eventname");
Code at the reciver....
function fn_selection()
var info=EPCM.loadClientData("urn:namesapce","key");
document.myform.name.value=info;
EPCM.subscribeEvent("urn:namesapce","eventname",fn_selection);
This is the javascript code for triggering and subscribing  events in between iviews.
Hope this Helps
