Please help..it's Urgent..How to fetch the value from table row from Page

Question

Hi,
I have created a table with 2 LOV's , LOV2 is dependent on LOV2.
Here I can not use the general Dependent LOV concept, as these values are coming from 2 different LookUps.
I am not able to fetch the user input for LOV1 (from page) .that is why not able to set the where cluse fro 2nd LOVVO.
I have used this code:
if ("ViolationCat".equals(lovInputSourceId)) {
OAMessageLovInputBean msglov =
(OAMessageLovInputBean)webBean.findChildRecursive("ViolationCat");
// String p_violation_category = "'"+(String)msglov.getValue(pageContext)+"'";
String p_violation_category =
(String)msglov.getValue(pageContext);
// System.out.println(" p_violation_category =" +
// p_violation_category);
String v_violation_category = "";
//System.out.println("vcat=" + vCat);
OAViewObject violationVO =
(OAViewObject)am.findViewObject("SNI_Violation_DtlsVO2");
Number vcatViolationIdnum =
(Number)violationVO.getCurrentRow().getAttribute("ViolationId");
String vcatViolationId = "" + vcatViolationIdnum;
pageContext.putTransactionValue("vcatViolationId",
vcatViolationId);
pageContext.putTransactionValue("p_violation_category",
p_violation_category);
String query =
" SELECT LOOKUP_CODE, \n" + " MEANING, \n" +
" LOOKUP_TYPE \n" +
" FROM apps.fnd_lookup_values \n" +
" WHERE LOOKUP_TYPE ='SNI_VIOLATION_CATEGORY' AND MEANING=?";
PreparedStatement ps = txn.createPreparedStatement(query, 1);
try {
ps.setString(1, p_violation_category);
ResultSet rs = ps.executeQuery();
//System.out.println("before while,");
// rs.next();
// v_violation_category = rs.getString("LOOKUP_CODE");
// System.out.println("v_violation_category="+v_violation_category);
while (rs.next()) {
//System.out.println("inside while");
v_violation_category = rs.getString("LOOKUP_CODE");
// System.out.println("v_violation_category=" +
// v_violation_category);
ps.close();
} //try ends
catch (Exception e) {
e.getMessage();
//System.out.println("in catch.." + e.getMessage());
OAViewObject subCatVO =
(OAViewObject)am.findViewObject("SNI_ViolationSubCategoryVO1");
//System.out.println("get VO before where clause: subCatVO::"+subCatVO.getQuery());
subCatVO.setWhereClause("LOOKUP_TYPE like '%SNI_VIOL_SUB_CAT_" +
v_violation_category + "'");
System.out.println("after set where clause VO: subCat VO::" +
subCatVO.getQuery());
subCatVO.executeQuery();
// System.out.println("query of subCat VO::" +
// subCatVO.getQuery());
//End of sub category Validation
It is working fine only for the 1st row of teh table.
I have tried to fetch the value using :
String violationCategory = (String)violationVO.getCurrentRow().getAttribute("ViolationCategory");
String violationSubcategory = (String)violationVO.getCurrentRow().getAttribute("ViolationSubcategory");
But it is fetching null value.
Please tell me how can I able to fetch the values.

Hi
in your scenarion,first u have to identify the particular row of table where the changes is being made ,u have to use this code .when u select the lov ,first it will give the row refernce and then u have to catch the lov event
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
String event = pageContext.getParameter("event");
if ("<ItemPPREventName>").equals(event))
// Get the identifier of the PPR event source row
String rowReference =
262
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] parameters = { rowReference };
// Pass the rowReference to a "handler" method in the application module.
am.invokeMethod("<handleSomeEvent>", parameters);
In your application module's "handler" method, add the following code to access the source row:
OARow row = (OARow)findRowByRef(rowReference);
if (row != null)
thanx
