Custom page with internal id as parameters: convert to names

Question

Hi,
I am new to OAFramework... just so that you know.
I have a custom page, called from a link on a notiification, which has a number of parameers coming in. These parameters are internal ids. Do I use validation view object to translate those id's into names and numbers? Or is that usually done via a different technique?
thanks

Ok, here is what I did.
I have a number of internal id's coming in as parameter.
Created 2 VVO's.
- InvoiceDataVVO
- personDataVVO
Actually I created 3 VVO's, because I thought I would be able to use a VVO a second time for another translation but that seemed to be wrong thinking.
So, third VVO (which is identical to personDataVVO)
- ccPersonDataVVO
Connected them to the AM (NotifySupplierAM).
Created the initQuery method in the corresponding VVOImpl classes
public void initQuery(String PersonId)
setWhereClauseParams(null); // Always reset
setWhereClauseParam(0, PersonId);
executeQuery();
In the controller NotifySupplierCO I added the following in the processRequest
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
initMailData(pageContext, webBean);
code for initMailData
* Display the proper mailing info on the page
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
public void initMailData(OAPageContext pageContext, OAWebBean webBean)
Enumeration num = pageContext.getParameterNames();
Hashtable hm = new Hashtable();
while (num.hasMoreElements()) {
String element = num.nextElement().toString();
hm.put(element, pageContext.getParameter(element) );
String InvoiceId = hm.get("invoiceId").toString();
String VendorId = hm.get("vendorId").toString();
String AccountantUserId = hm.get("accountantUserId").toString();
String SenderUserId = hm.get("senderUserId").toString();
String RespId = hm.get("respId").toString();
String RespApplId = hm.get("respApplId").toString();
String OrgId = hm.get("orgId").toString();
System.out.println("InvoiceId : " + InvoiceId);
System.out.println("VendorId : " + VendorId);
System.out.println("AccountUserId : " + AccountantUserId);
System.out.println("SenderUserId : " + SenderUserId);
System.out.println("RespId : " + RespId);
System.out.println("RespApplId : " + RespApplId);
System.out.println("OrgId : " + OrgId);
// Translate the parameter values into names and stuff
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable[] parameters = { InvoiceId, AccountantUserId, SenderUserId  };
am.invokeMethod("queryMailDataById", parameters);
// Put the values to the page fields (for the items which are not mapped
// to a VVO
OAMessageTextInputBean itemMailBodyTextBean = (OAMessageTextInputBean)webBean.findChildRecursive("MailBodyText");
OAMessageCheckBoxBean itemIncludeAttachmentBean = (OAMessageCheckBoxBean)webBean.findChildRecursive("IncludeAttachment");
itemMailBodyTextBean.setValue(pageContext,null);
itemIncludeAttachmentBean.setValue(pageContext, 'Y');
} // initMailData
This calls queryMailDataById in the AM, which looks like this.
* Translate the incoming id values into the nessecary data values
* to be displayed on the page
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
public void queryMailDataById( String InvoiceId
, String AccountantId
, String SenderId
InvoiceDataVVOImpl voInv = getInvoiceDataVVO1();
voInv.initQuery(InvoiceId);
personDataVVOImpl voSend = getpersonDataVVO1();
voSend.initQuery(SenderId);
ccPersonDataVVOImpl voAccount = getccPersonDataVVO1();
voAccount.initQuery(AccountantId);
The input fields on the page are mapped to the VVO's.
example:
View Instance: InvoiceDataVVO1
View Attribute: VendorEmail
That did the trick.
