Issue with File Download(messageDownload) on Search Page.

Question

Hi,
I created a custom OAF search page which fetches values from one table. The document in getting stored in my custom table in a BLOB colums and NOT in FND_LOBS.
The table has 3 collumns along with others:
1st is primary key (Record_Seq) ==> number data type
2nd to store actual file name (File1Name) ==> varcahar2 data type
3rd to store the actual uploaded data (File1Data) ==> BLOB data type
The reason for having the “File1Name” is so that I can display the original file name of the document that was uploaded, instead of just the “view” in the search page results .
On the File1Data BLOB and created a messageDownload for that under query results table with following details:
ID : File1Data
ItemStyle : messageDownload
FileMIME Type : pdf
Datatype : BLOB
View Instance : LacEmpExposureVO1
view Attribute : File1Name
File View Attribute : File1Data
When I click on the "File1Name" data hyperlink, it is opening only the first document corresponding to the first record in the search page results.
For example, If my search page returns 10 rows then when I click on the file1name on any row, It is open the first row file name only.
I have a primary key column(RECORD_SEQ) in the Table / EO / VO which is displayed in the search page results.
Also one weird thing is happening:
If I try to do this more than 2 times then it is opening the update page with the first record from the search page results…
I tried to print the context and it is nul the first time, But the second time then context is changing to "update". Dont know how this is happening????
Any advice is greatly appreciated as it is very crucial for me to get this resolved ASAP. I have looked at several forums and did a lot of things as advised in the forums . But nothing seems to work for me.
Thanks,
Mir
CO code for the search page
===========================
if (pageContext.getParameter("Create")!= null)
System.out.println("Into LacEmpExposureCO in PROCESS FORM REQUEST with Context of CREATE");
pageContext.setForwardURL
("OA.jsp?page=/lac/oracle/apps/lac/lacempexposure/webui/LacEmpExposureCreatePG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
true, //Retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_YES,
OAWebBeanConstants.IGNORE_MESSAGES);
else if ("update".equals(pageContext.getParameter(EVENT_PARAM)))
System.out.println("Into LacEmpExposureCO in PROCESS FORM REQUEST with Context of UPDATE");
System.out.println("LacEmpExposureCO ==> RecordSeq in PROCESS FORM REQUEST is: " + RecordSeq);
HashMap params = new HashMap(1);
params.put("RecordSeq", RecordSeq);
pageContext.setForwardURL
("OA.jsp?page=/lac/oracle/apps/lac/lacempexposure/webui/LacEmpExposureUpdatePG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
params,
true, //Retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO, // Do not display breadcrumbs
OAWebBeanConstants.IGNORE_MESSAGES);
else {           
String strEvent = pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM);
System.out.println(strEvent);
System.out.println("Into the last ELSE part in LacEmpExposureCO.java");
