Refresh only page item while submitting data from the popup window

Question

Hi All,
I'm pretty new to Apex .....
I have a form with text items as first few entries and then a radio button list and few text items again. On selecting certain radio button I have a popup window which acts as an interface for the next text item in the calling page. The purpose of having the popup window is that the text item following the radio button takes the input with certain character delimiters along with the data. Instead of using delimiters while entering the data I want a meaningful data to be keyed in the popup window and all the string operation to be done as a background process. I have been successful this far. I'm using the below javascript on click of the submit button.
javascript:doSubmit();
window.opener.doSubmit('REFRESH');
window.close();
On doing this I'm losing the values submitted for the items prior to the radio button(including radio button). Please note, I have a dynamic action set on page load to reset the values. Is it possible to refresh just the page item from the popup window.
Also, I tried excluding the window.opener.doSubmit('REFRESH'); from the above javascript. It sets the item with the expected value (viewed it in the session items, however I would like to view the concatenated string on my calling page) but following this there is an insert operation which uses all the necessary items in the form. All values except the value returned from the popup window is populated into the table. Am I missing something.
Any help in this regard is appreciated.
Thank you!!!

Ganesh

Value set using Javascript is only in your browser page but is not yet available in the session. This is why the report doesn't return the expected output.
Before refreshing the report you would need to set the session state of this item.
You can set it after you assign the item a new value or before the report is refreshed
For Interactive Reports, this is available built in
you can go to Report Attributes >Advanced Attributes -> Page Items to Submit and specify P2_X1 for the field(and any other page item that the report is dependent on)
For standard reports, you can create a Dynamic Action that is triggered "before refresh" of the report's region, and choose PLSQL as the action types, give a dummy BEGIN NULL END; for the code and specify this item name in the page item to submit field so that it sets the items's value in session.
