Multiple session bean problem

Question

Hi,
I am developing an admin module to my web app and have created a 2nd session bean to manage data within the admin component of the site just to keep things cleaner and more logical. However there is a problem which I cannot overcome.
The source code to my main website is located in soulsurfing package. The source code to my admin website is located in soulsurfing.admin package. Inside this package is the java code to my admin web pages and a 2nd session bean called adminSessionBean. So far so good.
I dropped a database table into my admin page which created a cachedrowset (CustomerRowSet) in my adminSessionBean and a data provider on my admin page (CustomerDataProvider). Ok things are still going well until now.
There are two main issues i'm facing.
1. Setting a breakpoint in my code and trying to step through the code line by line (F10) fails whenever the adminSessionBean appears in the line of code. In actuality the system just hangs until I exit debug mode in which the page finishes loading ok. If I step into the code (F11) it still works ok and if there is no breakpoint at all it loads ok too so there is something wrong with the debugger.
2. Most importantly there is a problem with either the cachedrowset or the data provider because it simply does not return any data from the database. The sql query works fine in both MySQL and when running from creator too so no problem here. If I put a line of code in to capture the sql statement such as String test_var3 = getAdmin$adminSessionBean().getCustomerRowSet().getStatement().toString() a null exception is thrown. However if I ditch the 2nd session bean (adminSessionBean) and run everything exactly the same through the original session bean (SessionBean1) located in soulsurfing package then it all works fine so there must be conflict somewhere with having multiple session beans perhaps in different packages.
Can anybody help me?
Below is the java code to my web page that sets and executes the cachedrowset in the prerender method that is failing. Further below that is the code to my 2nd session bean.
Thanks.

Hi Harini,
What I didn't explain in my initial post is that there are more than 2 views in my application.  There are a total of 9 jsp's so far, so I coded multiple controllers due to the high amount of views.  After taking the HTMLB training class, I noticed that the examples used contained no more than 2 jsp's, so only 1 controller was needed.
However, I talked with another Portal developer, and he suggested that it would be simpler to code the application using only 1 controller.  The problem is, I will have 1 LOOOOONG controller since there are many buttons across all of the jsp's (hence many events that will need to be handled) and many beans that need to be populated.
Harini, thanks very much for offering to view my par file.  I think I have solved the problem on my own, but could you let me know what the design standard is for an application of this size?  Think of an online banking application that needs to handle bill payment (paying the bill, viewing past payments, etc.,).
Would you use 1 controller for this type of application?
Thanks very much for your help.
