Prgrmatic viewlink setting for hgrid is working for one level and not remai

Question

Hi All,
I have create 2 VO objects dynamicaly and created 2 VL's dynamically .I have a static HGrid.and iam setting viewlinks dynamically.It is working for 1 level but not another leve..For Example.. Grid id displaying projects to Tasks but not tasks to subtasks.
here is my code
public void createViewLink(){
OADBTransaction dbTransaction=getOADBTransaction();
OAViewObject obj = (OAViewObject)this.findViewObject("TestProjects1VO1");
OAViewObject obj1 = (OAViewObject)this.findViewObject("TestTasks1VO1");
AttributeDef[] prjLinkAttrs = new AttributeDef[] { obj.findAttributeDef("ProjectId") };
AttributeDef[] taskLinkAttrs = new AttributeDef[] { obj1.findAttributeDef("ProjectId") };
ViewLink vl = createViewLinkBetweenViewObjects("TestPrjToTestTasksVL","TestPrjToTasksAcc",
obj,prjLinkAttrs,obj1,taskLinkAttrs,null);
//OAViewObject obj3 = (OAViewObject)this.findViewObject("TestTasks1VO1");
OAViewObject obj2 = (OAViewObject)this.findViewObject("TestRecTasks1VO1");
AttributeDef[] taskAttrs = new AttributeDef[] { obj1.findAttributeDef("TaskId") };
AttributeDef[] parentTaskAttrs = new AttributeDef[] { obj2.findAttributeDef("ParentTaskId") };
ViewLink vl1 = createViewLinkBetweenViewObjects("TaskToTestTasksVL","TaskToTasksAcc",
obj1,taskAttrs,obj2,parentTaskAttrs,null);
OAHGridBean hgrid=(OAHGridBean)webBean.findChildRecursive("HGridRN");
OAHGridHierarchyBean hgridHierarchy = (OAHGridHierarchyBean)hgrid.findChildRecursive("TreeRN");
OATreeLevelBean treeChild = (OATreeLevelBean)hgridHierarchy.findChildRecursive("TreeRN");
OAWebBean nodeDef1 = (OAWebBean)treeChild.findChildRecursive("nodeDef1");
nodeDef1.setViewUsageName("TestProjects1VO1");
nodeDef1.setViewAttributeName("ProjectName");
OATreeChildBean childNode1 = (OATreeChildBean)treeChild.findChildRecursive("childNode1");
childNode1.setAttributeValue(VIEW_LINK_NAME,"TestPrjToTestTasksVL");
childNode1.setAttributeValue(VL_ACCESSOR_NAME_ATTR,"TestPrjToTasksAcc");
OAWebBean nodeDef2 = (OAWebBean)childNode1.findIndexedChild(childNode1,"nodeDef2");
nodeDef2.setAttributeValue(VIEW_USAGE_NAME, "TestTasks1VO1");
nodeDef2.setAttributeValue(VIEW_ATTRIBUTE_NAME,"TaskName");
%%%%%%%%%%%%%%%Till Here grid is getting data%%%%%%%%%%%%
This node is not getting data............i.e sub tasks are not getting data
OATreeChildBean childNode2 = (OATreeChildBean)childNode1.findIndexedChildRecursive("childNode2");
childNode2.setAttributeValue(VIEW_LINK_NAME,"TaskToTestTasksVL1");
childNode2.setAttributeValue(VL_ACCESSOR_NAME_ATTR,"TaskToTasksAcc");
OAWebBean nodeDef3 = (OAWebBean)childNode2.findIndexedChild(childNode2,"nodeDef3");
nodeDef3.setAttributeValue(VIEW_USAGE_NAME, "TestRecTasks1VO1");
nodeDef3.setAttributeValue(VIEW_ATTRIBUTE_NAME,"TaskName");
Please help me .. ihave spent my whole daya on this issue.
Thanks

Sure Sumit.
OADBTransaction dbTransaction=getOADBTransaction();
OAViewObject obj = (OAViewObject)this.findViewObject("TestProjects1VO1");
OAViewObject obj1 = (OAViewObject)this.findViewObject("TestTasks1VO1");
OAViewObject obj2 = (OAViewObject)this.findViewObject("TestRecTasks1VO1");
// OAViewObject obj3 = (OAViewObject)this.findViewObject("RecTasks1VO1");
AttributeDef[] prjLinkAttrs = new AttributeDef[] { obj.findAttributeDef("ProjectId") };
AttributeDef[] taskLinkAttrs = new AttributeDef[] { obj1.findAttributeDef("ProjectId") };
ViewLink vl = createViewLinkBetweenViewObjects("TestPrjToTestTasksVL","TestPrjToTasksAcc",
obj,prjLinkAttrs,obj1,taskLinkAttrs,null);
AttributeDef[] taskAttrs = new AttributeDef[] { obj1.findAttributeDef("TaskId") };
AttributeDef[] parentTaskAttrs = new AttributeDef[] { obj2.findAttributeDef("ParentTaskId") };
*************This cide was missing ...********************************
/* Retrieve the first row of the master rowset */
Row firstDept = obj.first();
/* Get iterator over details collection via the view link accessor attribute */
RowSetIterator empsInDeptRowSet = (RowSetIterator)firstDept.getAttribute("TestPrjToTasksAcc");
/* Get view object created by the framework to handle view link traversal */
ViewObject viewObjectForAccessorRowSet = empsInDeptRowSet.getRowSet().getViewObject();
/* Now, create the 2nd-level detail between this view object, and reports */
*************This cide was missing ...********************************
ViewLink vl1 = createViewLinkBetweenViewObjects("TaskToTestTasksVL","TaskToTasksAcc",
viewObjectForAccessorRowSet ,taskAttrs,obj2,parentTaskAttrs,null);
I the above vl1 i gave obj1 before .. that was the difference...BAsically using the accessor ... if we give as source for next levevl .. it worked.
Both ViewLinks were separate and now there is a link ............ :)
Now iam facing problem for recursion ......... :)
