Passing an Arraylist from ApplicationModule to Managed bean

Question

Hi,
We are using the cg$errors package to stack database errors,warnings and informationals. In forms you can see them in messages and we want to see the same message in our ADF application.
I created an pl/sql procedure that returns the messages. In my application module I have created an method that calls the pl/sql-procedure. So far so good.
      try {
         // 1. Create a JDBC PreparedStatement for
         st = getDBTransaction().createCallableStatement( "begin test_rlo.getFeedback(?,?,?);end;", 0 );
         // 2. Define out parameters
         st.registerOutParameter( 1, Types.VARCHAR );
         st.registerOutParameter( 2, Types.VARCHAR );
         st.registerOutParameter( 3, Types.VARCHAR );
         // 3. Execute the statement
         st.executeUpdate();
         // 4. Build return objectsss
         informationArray = stringToArray( st.getString( 1 ) );
         warningArray = stringToArray( st.getString( 2 ) );
         errorArray = stringToArray( st.getString( 3 ) );
         System.out.println("info : "+informationArray.size());
         System.out.println("warn : "+warningArray.size());
         System.out.println("error: "+errorArray.size());
      } catch ( SQLException e ) {
         throw new JboException( e );
      } finally {
         if ( st != null ) {
            try {
               // 5. Close the statement
               st.close();
            } catch ( SQLException e ) {
      }I have some trouble with the last step. Bringing the messages to my adf-page.
I have created the method as an action in the PageDef.
    <methodAction id="getDBFeedback"
                  InstanceName="RelatieAppServiceDataControl.dataProvider"
                  DataControl="RelatieAppServiceDataControl"
                  MethodName="getDBFeedback" RequiresUpdateModel="true"
                  Action="999" IsViewObjectMethod="false">
      <NamedData NDName="informationArray"
                 NDValue="${DBFeedbackBean.informationArray}"
                 NDType="java.util.ArrayList"/>
      <NamedData NDName="warningArray" NDValue="${DBFeedbackBean.warningArray}"
                 NDType="java.util.ArrayList"/>
      <NamedData NDName="errorArray" NDValue="${DBFeedbackBean.errorArray}"
                 NDType="java.util.ArrayList"/>
    </methodAction>I created an managed-bean(DBFeedbackBean) on the request scope. In my managed-bean I defined three arraylists (warning,information and error) .
In the constructor I execute the method action:
      DCBindingContainer bindings = getCurrentBindingContainer();
      OperationBinding operationBinding = ( OperationBinding )bindings.getOperationBinding( "getDBFeedback" );
      operationBinding.getParamsMap().put("informationArray", informationArray);
      operationBinding.getParamsMap().put("warningArray", warningArray);
      operationBinding.getParamsMap().put("errorArray", errorArray); 
      operationBinding.execute();Within the application module I can log several informationals,warnings and errors but the arrays stay empty.
What am I missing here?

Hi,
this is similar to what you are trying to do:
AM Method
    public String[] syncBudgetAmounts(Double allocationId){
        getDBTransaction().commit();     
        String result = new String();
        String message = new String();
        try  {
            String sql = "call plus_budget.sync_budget_amounts(?,?,?,?)";
            CallableStatement stmt = getDBTransaction().createCallableStatement(sql, 0);
            stmt = getDBTransaction().createCallableStatement(sql, 0);
            stmt.setDouble(1, allocationId);
            stmt.setString(2, getUserName());
            stmt.registerOutParameter(3,Types.VARCHAR);
            stmt.registerOutParameter(4,Types.VARCHAR);
            stmt.execute();
            result = stmt.getString(3);
            message = stmt.getString(4);
            stmt.close();
            getBudgetAllocationsView1().executeQuery();
        } catch (Exception ex)  {
            result = "Error";
            message = ex.getMessage();
            ex.printStackTrace();
        return new String[]{result, message};
    }pageDef:
<methodAction id="syncBudgetAmounts"
                  InstanceName="BudgetAdminServiceDataControl.dataProvider"
                  DataControl="BudgetAdminServiceDataControl"
                  MethodName="syncBudgetAmounts" RequiresUpdateModel="true"
                  Action="999" IsViewObjectMethod="false"
                  ReturnName="BudgetAdminServiceDataControl.methodResults.BudgetAdminServiceDataControl_dataProvider_syncBudgetAmounts_result">
        <NamedData NDName="allocationId" NDValue="#{row.AllocationId}" NDType="java.lang.Double"/>
    </methodAction>Page:
<afh:rowLayout rendered="#{bindings.syncBudgetAmounts.result[0] != null}"
                             width="90%">
