How to display Attachments on OAF page for different entities

Question

Hi,
I have a requirement where I have to create an attachment page to display the attachments dynamically at run time depending upon the values passed such as Entity Name, Primary Key values, Category Id values.
I have a query to give me the attachments related data from the tables like fnd_documents_vl, fnd_attached_documents, fnd_document_entities, fnd_document_categories_tl.
Now, as I read on the forum, I can make use of Oracle's seeded functionality on attachments and display attachments but in my requirement I don't have one specific entity. I have below query which gives data directly with respect to all entities from fnd tables. The name of entity and primary keys will come at run time. So, how can I make use of below query and display attachments in such a case?
I am very new to OAf and any help will be really appreciated.
Thanks in Advance,
Shalini

Hi Peddy,
Thanks a lot for your guidance. I tried implementing the code in PR but I am stuck at one error. I am not able to programmatically add a new Entity ID and its attributes at run time. To make it more clear: In Jdev I created an Entity and its mappings at design time. Now, I am able to use getEntitymappings() and setEntityMappings() to modify the attributes of exiting Enity but I am not able to add/append new Entity ID to the existing one. It throws - java.lang.ArrayIndexOutOfBoundsException: 1 error.
Please any one review the below code snippet and let me know whether I am missing something to make it work.
Below is the Code that I have written so far:
====================================================
OAAttachmentTableBean attBean = (OAAttachmentTableBean)webBean.findChildRecursive("attachTable");
Dictionary[] entityMaps = attBean.getEntityMappings();
entityMaps[0].remove("entityId");
entityMaps[0].put("entityId","OE_ORDER_HEADERS");
entityMaps[0].remove("insertAllowed");
entityMaps[0].remove("updateAllowed");
entityMaps[0].remove("deleteAllowed");
entityMaps[0].put("insertAllowed", false);
entityMaps[0].put("updateAllowed", false);
entityMaps[0].put("deleteAllowed", false);
// Adding Second Entity
// Getting ArrayIndexOutOfBoundsException at below line. As i saw that getEntityMappings() returns only array of size :1 and that is teh reason I am getting error, so How can I increase the size dynamically to add new Entity or is there any other way?
entityMaps[1].put("entityId", "XX_LINK_ENTITY"); // entity id
entityMaps[1].put("showAll", false); // show all property
entityMaps[1].put("insertAllowed", false);
entityMaps[1].put("deleteAllowed", false);
entityMaps[1].put("updateAllowed", false);
// Adding Primary Key to Second Entity
String[] pkAttrNames = new String[1];
pkAttrNames[0] = "Pk1Value"; // pk view attribute name
entityMaps[1].put("pkColumns", pkAttrNames);
// Setting Category Values for first Entity
Integer CatValue = 1000486;
Integer[] categories = new Integer[2]; // categories
categories[0] = new Integer(1);
categories[1] = CatValue;
// Setting Category Values for Second Entity
Integer[] categories2 = new Integer[1]; // categories
categories2[0] = new Integer(1); //MISC
attBean.setEntityMappings(entityMaps);
attBean.setDynamicCategoriesMap("OE_ORDER_HEADERS",categories);
attBean.setDynamicCategoriesMap("XX_LINK_ENTITY",categories2);
Thanks & Best Regards,
