How to Update Particular row in a table from OAF page

Question

Hi Can anyone please help me on the following requirement:
In my oaf page i am displaying table values(supplier site details from base tables) with update and delete icons . When i click on update button a new page opens in which we used to update the values and click on apply button which again comes back to the original page.
So when i click on apply button on update page i have to first search for the site in the site table whether it exists or not, if not exists i have to create a new row and save the data, if site exists in the table i have to update the row of a table for that particular site. I have written code for this but unable to achive the requirement, it is not updating the existing row of the table. And i am doing all this on the Temp tables.
So now when i save, previous transaction is also updating along with the current transaction. That means when i m trying to save 2nd transaction values , 1st transactions values are getting updated with the 2nd transaction values(2 rows are getting updated)
Can anyone help me with the code used for updating the current row of the table. Please correct me if i m doing anyting wrong in code.
following is the current code i m using and which is failing :
Controller Code
if(pcontactaction.equals("createECdetailsEvent")) {
String currentSiteName=pageContext.getParameter("SiteName");
System.out.println("Selected Site Name is : " + currentSiteName);
Serializable x[]={reqNum,suppId,currentSiteName,pnotifMethod,pfaxNum};
System.out.println("Invoking AM Method.........");
am.invokeMethod("initCreateECDetails",x);
System.out.println("initCreateECDetails Method Executed. ");
//am.invokeMethod("save");
localOAApplicationModule.getTransaction().commit();
pageContext.setForwardURL(
"OA.jsp?page=/oracle/apps/floaf/flpos/supregister/webui/ECDetailsPG"
, null //not needed as we are retaining menu context
,OAWebBeanConstants.KEEP_MENU_CONTEXT

Answer 1

Please answer following:
1. Are you using EO based VOs or ReadOnly VO?
2. What is your VO Query for the search and update?
3. Why have you based your logic on site_name; you should have used site_id?
4.Are you getting correct site name in handling createECdetailsEvent event in CO?
5. In case of update are you getting correct values on the Update Site Details?
6. On coming back from Update page to Supplier Site Search page, do you see old values of the site or the new values in the results table?
Please share the screenshot if possible.
