Addrow() and #rownum#

Question

Hello every one. I have searched this forum extensively for a solution but haven't been able to find one.
Apex: 4.1.00.23
DB: 11.1.07
In a tabular fomr, I am using APEX_ITEM.TEXT in the following way:
APEX_ITEM.TEXT(10,email,40,null,'STYLE="background:#d3d3d3;" readonly="readonly" onclick="window.open(''f?p=106:10:&APP_SESSION.::::'',''Search_User'',''width=700,height=350'')"','f10_'||'#ROWNUM#')
There is an add button that calls JavaScript addrow() function to add rows to the form. When a row is added, the tabular form built in text boxes get the next #ROWNUM# for the id. For example f01_010, f02_010. The custom
APEX_ITEM.TEXT mentioned above gets 0 for the rownum so the id is f10_0. So my question is how can I get the next value of the rownum to populate the id? I understand that #ROWNUM# comes from the database and since the page has not been submitted, the new row does not have a value. Is there a way to get current maximum rownum and may be add 1 to it to get the next value for the id?
Thanks,
Usman

Thanks for the reply. I took your suggestion and decided to do it without custom tabular form. The behavior I wanted was that when a user clicks on the text box it opens a pop up window from which the user can select the list of values. This pop up window displays a report with various custom information (hence I could not use built in pop up LOV). I ended up doing this with dynamic action.
Element Attributes of the tabular form column: class="email" STYLE="background:#d3d3d3;" readonly="readonly"
Dynamic Action:
Event= Click
JQuery Selector = .email
Action= The following java script code:
var id=this.triggeringElement.id;
var name=this.triggeringElement.value;
window.open('f?p=106:10:&APP_SESSION.::::P10_SET_ITEM,P10_USER,P10_SUBMIT_FLAG:'+id+','+name+',N','Search_User','width=700,height=350');Thanks for your help.
