Attachment Table with 2 PK columns using personalization

Hi Friends!

Is it possible to add an attachment table just using personalization but using 2 PK columns?:

entity_name: PA_DRAFT_INVOICES
pk1_value: <project_id>
pk2_value:     <draft_invoice_num>

I've achieved to create it via personalizacion but I don't know how to add the second pk column. It works to add attachments and query them but only with one PK column. I've followed Anil's advices:

[Attachments-self-service-oracle-apps|http://apps2fusion.com/apps-training/apps-functional-documents/75-ame-sshr/433-attachments-self-service-oracle-apps]

In the other hand I've extended the Controller and added the Attachment Table programmatically with the 2 PK columns and I can upload attachments, BUT can't query them as the attachments region is empty. I've checked that record has been created OK in fnd_attached_documents table with this approach.

Please help... what am I doing wrong???

Thanks a lot in advance,
Jose.

This is the code for adding programmatically the Attachment Table:

-----------------------------------------------------------------------------------
OAAttachmentTableBean attTable = (OAAttachmentTableBean)pageContext.getWebBeanFactory().createWebBean(pageContext, OAWebBeanConstants.ATTACHMENT_TABLE_BEAN,null,null);

attTable.setID("xxEverisDraftInvAttachmentId");
attTable.setAutoCommitEnabled(true);
attTable.setViewUsageName("InvDetailsVO");
attTable.setSearchRegionDisplayed(false);
attTable.setDocumentCatalogEnabled(false);

attTable.setText("Upload Draft Invoice Extra Documentation");

Dictionary firstEntity = new ArrayMap(4);
firstEntity.put("entityId", "PA_DRAFT_INVOICES_ALL"); // entity id
firstEntity.put("showAll", Boolean.FALSE); // show all property
firstEntity.put("insertAllowed", Boolean.TRUE);
firstEntity.put("deleteAllowed", Boolean.TRUE);
firstEntity.put("updateAllowed", Boolean.TRUE);

String[] pkAttrNames = new String[2];
pkAttrNames[0] = "ProjectId"; // pk view attribute name
pkAttrNames[1] = "DraftInvoiceNum"; // pk view attribute name
firstEntity.put("pkColumns", pkAttrNames);

Integer[] categories = new Integer[1]; // categories
categories[0] = new Integer(1); //MISC

firstEntity.put("categories", categories);
String[] statuses = new String[2]; //attachment status filter
statuses[0] = "pending";
statuses[1] = "failed";

firstEntity.put("statuses",statuses);
Dictionary[] entityMaps = new Dictionary[1];
entityMaps[0] = firstEntity;

attTable.setEntityMappings(entityMaps);
