I have an application designed as follows.

It is a travel claim reimburment app. It has two tabs:

1. My Claims : shows all reimbursment claims made so far

2. My Account: showing my details

    
It has number of claims on the Left and when selected displays Entries on 
the Right.

The picture of the view expected is attached.

I have made the following Views.

AppView : for Entire App which has tab panel and tabs

MyAccountsView : for contents under MyAccount Tab.

MyClaims View : for contents under Myclaims Tab. This has two panels. The 
one in left loads with the claims. The right is empty till a claim is 
selected to view.

SelectedClaimView : for panel on the right hand side,which displays the 
claimentries of selected claim..


 Each view has a correponding place and activity.


 These are th following requirements which I am getting difficulty while 
creating my application:


 *When I click on claim on left hand panel the right hand panel must show 
claim entries within selectedClaimView. When I click another claim the list 
must be populated by contents of that claim. I also want history support 
for this claim selection.*


 I am facing following problems while designing:

   1. 
   
   How to add nested activities. e.g. When I select MyClaimsTab all claims 
   must load up in left panel. On Selection of claim the claim entries must 
   load in right panel via selected claims view. However calling an activity 
   and changing the place stops the calling activity.
   2. 
   
   Also Both the activities in both tabs must run simultaneosly and history 
   must be maintained between tab switches. This is something I dont know how 
   to do and would appreciate suggestions.
