Row highlight in master detail

Question

I've created a master with a detail report on the same page so that when you click a row in the upper (master) region, you see the details in the lower region. At the same time the row in the upper region gets highlighted so you know what details you are looking at.
I did this as follows:
Create an application item CONTEXT_ID.
In the link in the master region CONTEXT_ID gets set to the row #ID#.
The detail region is based on a report template with column templates based on plsql expression:
condition for the non-selected rows:
v('CONTEXT_ID')is null or #ID#!=v('CONTEXT_ID')
condition for the selected row:
#ID#=v('CONTEXT_ID')
I'm reasonably happy with this solution it's easy to implement and works as long as your master table has a column named ID. The only drawback I find is that you have to specifically set CONTEXT_ID to null whenever you navigate to a page that uses this construction.
It would be interesting to hear what other solutions are out there that to the same kind of thing.

Answer 1

Yes, I did set the partial trigger. That's why when manually select the row on the master table, the detail table get refreshed. The problem is the first time entering the page, and not row get selected automatically in the master table. Here is the code snipplet of the detail table:
<af:table value="#{bindings.ItasLookupCodesVO1.collectionModel}"
var="row" rows="#{bindings.ItasLookupCodesVO1.rangeSize}"
emptyText="#{bindings.ItasLookupCodesVO1.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.ItasLookupCodesVO1.rangeSize}"
rowBandingInterval="0"
filterModel="#{bindings.ItasLookupCodesVO1Query.queryDescriptor}"
queryListener="#{bindings.ItasLookupCodesVO1Query.processQuery}"
filterVisible="true" varStatus="vs"
selectedRowKeys="#{bindings.ItasLookupCodesVO1.collectionModel.selectedRow}"
selectionListener="#{bindings.ItasLookupCodesVO1.collectionModel.makeCurrent}"
rowSelection="single" id="t2" partialTriggers=":::pc1:t1"
editingMode="clickToEdit" summary="Lookup Codes">
The table is a child of a panelCollection.
Any more ideas?
Thanks.
