ADF Issue with Tree Table , Child Row not getting rendered.

Question

Hi All,
I am trying to show a single Level Master-Detail Table via ADF Tree Table.
I have MasterVO : InventoryVO (1 SubInventoryCode)
DetailVO: SubInventoryVO (n :SubInventoryCode)
Both VOs are SQL query based VO with bindVariables.
I have a viewLink between MasterVO and ChildVO (1:n relationship)
I dragged and drop the MasterVO as a tree Table. I added the Rule in the Tree Binding too.
I have the Tree table under a Tab , I execute the AM impl method when the Tab is clicked where I set the bindvariables of the MasterVO and ChildVO and execute it.
when I run the Page , the VO query gets executed but the I am able to see only the MasterVO Datas, and when I click MasterVO ROW , the Table doesnt expand and it doesnt render any ChildVO ROws.

Answer 1

I was able to find the issue which is causing the problem, both the VOs are SQL Query Based VOs.
The ChildVO (SubInventoryVO) is has a bindvariable in its Query, which is losing its value when the viewlink accessor query gets appended to it.
Please find the query below
SELECT * FROM (SELECT MOTV.ORGANIZATION_CODE, MOTV.SUBINVENTORY_CODE  
FROM MTL_ONHAND_TOTAL_V MOTV
WHERE INVENTORY_ITEM_ID = :P_INVENTORY_ITEM_ID) QRSLT  WHERE ORGANIZATION_CODE = :Bind_OrganizationCode Though I am setting the VO query before the Table is rendered, ":P_INVENTORY_ITEM_ID".
Its Losing its value, when the above whereclause "ORGANIZATION_CODE = :Bind_OrganizationCode " gets appended to it.
I am thinking to use ExecuteWithParams Operation on SelectionListener method of the Tree Table to set the ":P_INVENTORY_ITEM_ID" bind variable, but I also want the viewLinkAccessor rule also to be applied ..
Please suggest me how to retain the implicit bindVariable of the Query.
