JSF and ADFBC: How to Run a method every time the page is posted back

Question

Hi everyone,
I am using ADFBC and JSF in my project, and there is a page which runs the following logic: The page displays a set of radio options and a submit button. It has a total of 4 options, but they never display all at once. For example, when user enters the page for the first time, only selectItem 1 displays. When it clicks on the submit button, the page is posted back and hides the first select item, showing now the second, and so forth. The steps i did to achieve this are:
1 - Created a method on the App Module that inserts a row corresponding to the select item choice.
2 - Created another method that verifies which is the lastly entered row and returns a string containing the relevant attribute, for example, "E".
3 - Created the methodAction binding to run the insertMethod (1) and retrieveMethod (2).
4 - Created an invokeMethod executable for the retrieveMethod (2) and set the refresh property to "always".
5 - Created a variableIterator with a variable to hold the retrieveMethod return, also setting the refresh to "always".
6 - Lastly, bound the "rendered" attribute of each select item to the variable's value, for example "#{bindings.returnVariable == 'E'}
When i run the page, the logic works almost fine, except for one detail: When the user clicks the button that calls insertMethod, the page is posted back, and i assume the selectItems should be re-rendered accordingly. Yet, the button click inserts the row in the DB (called insertMethod) but keeps showing the previous radio item. If i restart OC4J, when i enter the page again the radio is now correct, showing the next option.
Do you know how can i tell the page that the model has been refreshed, so it runs the retrieveMethod again, alters the variable and the radio options without having to leave the page or restarting OC4J?
Thanks in advance for your help!

Hi all,
It seems i have figured out the error. It was a logic mistake on my method, ADF was doing the refreshes just fine. There is another little question i wanted to ask now: I need to execute a JSF Navigation Case when the page loads, in order to navigate to another page due to a certain condition. is there any way to run some logic to redirect the request before the page has been rendered, just like the onLoad() javascript event runs on the body every time it gets loaded?
What i'm trying to do exactly is this: When the login.jspx page runs the "success" navigation case, it goes to "page1.jspx". But before "page1.jspx" is loaded, i need to run an Application Module method to check for a certain situation; if this criteria is not met, i must run "fail" navigation case, from "page1.jspx" to "page2.jspx" without ever displaying page1.jspx.
Is it clear enough? Can you guys give me some pointers on how to do it?
Thanks a lot!
