Bc4j:RowScope on a Master Detail page always returns 0 rows for detail

Question

Hi,
I have a problem with a Master Detail page that is called from another page. The Master Detail page has two View Objects, Budgets and Budget Versions. These are linked properly in BC4J and when I use these VOs together I can navigate through the Budgets (master) and the Budget Versions (details) are populated correctly.
However, I want to navigate to this page from another page which lists all possible Budgets. I pass the key of the selected Budget to the Master Detail page and the correct Budget is displayed, BUT the Budget Versions are NOT displayed - I get 0 rows returned.
The mechanism I use to pass the selected Budget ID to my Master Detail page is:
<ctrl:property name="key">
<ctrl:selection name="ViewTable" key="key"/>
</ctrl:property>
My BC4J Registry is set up as follows:
<bc4j:registryDef>
<bc4j:rootAppModuleDef name="BudgetModule"
defFullName="BudgetPackage.BudgetPackageModule"
configName="BudgetPackageModuleLocal"
releaseMode="stateful">
<bc4j:viewObjectDef name="ItiBudgetsView1">
<bc4j:rowDef name="CurrentBudgetRow" usesCurrency="True">
<bc4j:propertyKey name="key"/>
</bc4j:rowDef>
</bc4j:viewObjectDef>
<bc4j:viewObjectDef name="ItiBudgetVersionsView2" rangeSize="15"/>
</bc4j:rootAppModuleDef>
</bc4j:registryDef>
I then use
<bc4j:rowScope name="CurrentBudgetRow">
to get the correct Budget row in my master VO. But this always returns 0 rows in my detail VO. If I comment out the rowScope element, I don't get the desired Budget row, but I do get the correct Budget Version rows displayed. Is the rowScope element on the Budget VO interfering with the Budget Version VO?
Hope this is not too confusing!!
Thanks,
Steve

Steve,
I tried to create a comparable set of two pages and initially ran into the same problem. I just realized that my issue (which I hope is yours too) is that the rootAppModule name was different across my two pages. This led to each page having its own application module instance, so the currency was different on each page.
By changing all of my pages to use the same application module name (in the registryDef, in the appModuleScope tags in the page, and in the findAppModule tags in the handlers), I resolved this problem.
My event handler to go to the master/detail page from the master page, FYI, looks like this:
  <event name="details" >
   <bc4j:findRootAppModule name="MyApp" >
    <!-- establish the ViewObject scope -->
    <bc4j:findViewObject name="CustomersView1" >
     <!-- find the selected Row -->
     <bc4j:findRowByKey>
      <bc4j:keyBinding>
       <bc4j:selectionKey name="viewTable" key="key" />
      </bc4j:keyBinding>
     </bc4j:findRowByKey>
    </bc4j:findViewObject>
    <bc4j:executeQuery />
    <go name="OrdersByCustomer_View" redirect="true" />
   </bc4j:findRootAppModule>                     
  </event>Hope this helps.
