How do I properly pass values into an input parameter form and app module?

Question

Using JDeveloper 11.1.1.4
I created an application module that calls a PL/SQL procedure that uses input parameters. I exposed this to the data control and dropped the object on a jsff as a input parameter form. I need to set some of the input parameters on this form from values gathered and stored in a pageFlowScope bean. What is the proper way so that the values will: 1. show on the form, and 2. get to the java code in the application module that calls my procedure? An example field from my form is:
        <af:inputText value="#{bindings.pPayerId.inputValue}" label="Payer ID"
                      required="#{bindings.pPayerId.hints.mandatory}"
                      columns="#{bindings.pPayerId.hints.displayWidth}"
                      maximumLength="#{bindings.pPayerId.hints.precision}"
                      shortDesc="#{bindings.pPayerId.hints.tooltip}" id="it8">
          <f:validator binding="#{bindings.pPayerId.validator}"/>
          <af:convertNumber groupingUsed="false" pattern="#{bindings.pPayerId.format}"/>
        </af:inputText>Thanks,
Troy

Thanks Shay for pointing me in that direction.
I didn't find the NDValue in the bindings, so I went to the pagedef xml and found it there. Changing the NDValue successfully delivered the value to the app module when the method was executed, but didn't show the value on the form. I had to add the same #{pageFlowScope.paramsBean.fileFormatParam} to the value of the input field and it now is working as needed.
