How to open URL as a popup window through BRANCH in APEX reports

Question

Hi
I am using APEX 4.0
I have a branch with a target type of URL. The branch is triggered by pressing a button. There is also a plsql process on the same button which fires at the process point of "On Submit-After Computations and Validations". I want to open the branch URL as the popup Window. I tried doing it with javascript, but then the plsql process doesn't execute. Any pointers will be helpful.
Thanks

You can use the apex.submit javascript function. This function allows to store some item value from session scope to database scope. So that a page process picks the correct item value. Not sure if it works with computations thou.
See the docs: JavaScript APIs
Example
Submits the current page with a REQUEST value of 'DELETE'.
apex.submit({ request:"DELETE", set:{"P1_DEPTNO":10, "P1_EMPNO":5433});
Then add a branch with type "branch to function returning URL" This page branch can be made conditional on the same request as the page process.
The returned url would be either include the javascript popup or window.open function or simply be the url. Important thing here would be to use a function that reads the url item  from database state, since at that moment the computation or page process will have set the item on database level, but it is not directly available on page level.
meaning ":p2_item" or v('P2_ITEM') should work. &P2_ITEM. in the url will probably not work.
