UIX/BC4J puzzle to render and unknown number of data tables.

Question

Hello, I have the next puzzle I haven't solved:
The requirements for a page are that it has to render Contract numbers as table titles and Bills dued to each contract as table content, something like this:
Contract No. 4353
Bill No. Date Amount
8799 25/04/2006 $800.00
3690 25/04/2006 $1,000.00
and then more tables like that as contract rows are found in a view object.
I have two linked view objects: the contractView and the billsView.
Besides, the contractView has attributes which should be rendered as the bills table footer (amount total for example).
I found a way to iterate over the contractView and then the billsView, with something like this:
<tableLayout>
    <contents childData="${bindings.contractViewIterator.allRowsInRange}">
         <rowLayout>
              <contents>
                <header text="${uix.current.contractNumber}"/>
                <table tableData="${uix.current.attributeValues[15].allRowsInRange}"/>
                <!-- the 15th attribute is the link accessor, so I'm getting the billsView here -->
                     <!-- and here would go more code to render the table contents -->
                </table>
              </contents>
          </rowLayout>
       </contents>
</tableLayout>This works fine for tables with no footer data, but I need to display the footer section of the table, the problem is that the footer section data is in the parent view (contracts) and I cannot reference it inside the <table> because there the "uix.current" object represents a row in the billView.
If someone has another idea of achieving this, I'd really appreciate it if you post it here, or a way to reference the parent uix.current object.
Thank you.

Answer 1

The only solution I came up with was to use the link accessor in the opposite direction, so I can get the contractView and display the totals on each column.
So, the next code does it:
<footer>
     <formattedText text="${uix.current.contracts.totalAmount}"/>
</footer>Where contracts is the backwards accessor to the parent view object and totalAmount the attribute name to display in the column footer. I had to generate the row implementation for both view objects to access attributes by name to make it easier.
I post the solution in case someone runs into the same problem.
Thank you.
