Dynamic Binding on BC4J bound UIX forms

Question

Hi
I'm attempting to use Dynamic Binding in my ADF UIX forms to determine whether to render certain fields on a form depending on the data in the current row.
Now, I completely understand how to bind the rendered="" attribute with a bound value determined by a static accessor to a bean, but the problem I am having is how to access the current row from my BC4J appModule.
The datascope beans only have access to the RenderingContext in the following manner:
<dataScope xmlns="http://xmlns.oracle.com/uix/ui">
<provider>
<data name="generic">
<method class="com.xxx.eim.tools.SetupFormDataBinder" method="getSetupState"/>
</data>
</provider>
The accessor:
public class SetupFormDataBinder {
static public Object getSetupState ( RenderingContext context
, String namespace
, String name
return new SetupFormBean(context);
which calls my bean.
But, the RenderingContext class does not seem to offer any accessors to the BC4J Configuration or similar.
So, how can I get to the data in the background...
Or, is this a poor way of doing it.... Can anyone offer any suggestions???
Cheers
Chris

You should scope your application module before entering dataScope:
        <bc4j:rootAppModuleScope name="EhiskommAM">
          <contents>
            <dataScope>
               <provider>
                  <data name="someData">
                    <method class="test.Test" method="getData"/>
                  </data>
               </provider>
               <contents>
               </contents>
            </dataScope>
          </contents>
        </bc4j:rootAppModuleScope>And remember to add app. module to the page definitions:
<page ....>
  <bc4j:registryDef>
    <bc4j:rootAppModuleDef name="AppModule" definition="test.AppModule" releaseMode="stateful">
    </bc4j:rootAppModuleDef>
  </bc4j:registryDef>
</page>
