Create view link programatically

Question

Hi all,
I am working on this weird requirement.
Basically, I have to create a detail table on a search resullt table. The search result is seeded search, for Item Advance search in Oracle PIM module which is not based upon a VO. The search result table is dynamically built at run time in the EgoItemSearchHelper class and that's where they build the search result VO (EgoItemSearchResultsVO).
Now, I need to access this VO in the controller class, and create a view link programatically between details table VO and this VO. The problem is since I do not have Impl class for the EgoItemSearchResultsVO, how do I accees the column that is the key attribute. Second I do not know how to create view link between the two VOs programatically.
Please help it's urgent.
Thanks

Pratap, My problem is the seeded VO is in seeded AM and my details VO will be in my custom AM, I don't know if we can have a view link between View objects that are in different AMs.
To bypass that problem, I tried to create a VO in the seeded AM programatically and then created a view link. Now since the AM is seeded, and I am adding my details VO to this AM programatically, I thought of creating a table also programatically on the detais VO.
In the end it does not work, I end up getting a show button on the main table, but when I click I get an error (Cannot find <null> attribute in the EOGITEMSEARCHRESULTVO) which is the seeded VO class. Unfortunately there is no boolean variable on the dynamic seeded VO, so don't know what to put in oatablebean.setDetailViewAttributeName("") method;
Any clues on this, appreciate all responses from the forum gurus.
ViewObject voEmp = oaapplicationmodule.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
ViewObject voEmp = am.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
AttributeDef[] prjLinkAttrs = new AttributeDef[]{oaapplicationmodule.findViewObject("EgoItemSearchResultsVO").findAttributeDef("INVENTORY_ITEM_ID_B")};
System.out.println("definition for attr = "+ prjLinkAttrs[0]);
AttributeDef[] taskLinkAttrs = new AttributeDef[]{voEmp.findAttributeDef("InvId") };
ViewLink vl = am.createViewLinkBetweenViewObjects("MyLink3",
"DetailInv", // accessor name--more on this below
am.findViewObject("EgoItemSearchResultsVO"), // master
prjLinkAttrs, // department attributes
voEmp, // detail
taskLinkAttrs, // employee attributes
null); // assoc clause
System.out.println("view link =" + vl.getName());
OATableBean tb = (OATableBean)createWebBean(oapagecontext,TABLE_BEAN,null,"table");
tb.setViewUsageName("MyEmp");
OAMessageStyledTextBean beans = (OAMessageStyledTextBean)createWebBean(oapagecontext,MESSAGE_STYLED_TEXT_BEAN,OAWebBeanConstants.VARCHAR2_DATATYPE,"number");
beans.setPrompt("column1");
beans.setViewUsageName("MyEmp");
beans.setViewAttributeName("InvId");
tb.addIndexedChild(beans);
oatablebean.setDetail((OAWebBean)tb);
oatablebean.setDetailViewAttributeName("SelectFlag"); // I just tried this, SelectFlag is not a boolean attribute though, is there a way to create a boolean attribute programatically for seeded VO EGOITEMSEARCHRESULTVO and set it here, will it help
oatablebean.setAllDetailsEnabled(true);
