Executing multiple methods off of one button

Question

Hi,
I have a parameter form based on the bind variables of a view object and I am trying to execute a second method via the "ExecuteWithParams" buttons.
I have included an <f:actionListener/> within my command button so my current button code is as follows:
<af:commandButton actionListener="#{bindings.ExecuteWithParams.execute}"
text="Submit"
disabled="#{!bindings.ExecuteWithParams.enabled}"
action="Go" partialSubmit="false">
<af:setActionListener from="#{bindings.Param1.inputValue}"
to="#{Input.Param1}"/>
<af:setActionListener from="#{bindings.Param2.inputValue}"
to="#{Input.Param2}"/>
<af:setActionListener from="#{bindings.Param3.inputValue}"
to="#{Input.Param3}"/>
<af:setActionListener from="#{bindings.Param4.inputValue}"
to="#{Input.Param4}"/>
<f:actionListener type="model.InputBean"/>
</af:commandButton>
model.InputBean:
public class InputBean extends AppModuleImpl implements ActionListener{
....... (includes sets and gets for Input.Param1-4)......
public void processAction(ActionEvent e){
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(fc);
DCDataControl dc = bc.findDataControl("AppModuleDataControl");
ApplicationModule am = (ApplicationModule)dc.getDataProvider();
AppModule service = (AppModule)am;
service.Method(Param1, Param2);
The service.Method() is called but errors out with a nullPointerException at both parameters.
I've hard coded the method and found it does work, I am just having trouble passing the variables in to start with.
The setActionListeners within the button code are so I can pass the values that are entered in each Param to the next page, I thought I might be able to
use these to set the Params for service.Method() but it seems this isn't happening.
Any Ideas?
Thanks,

Hi,
That has helped, I was able to execute my second method and redirect to the other page on the one button submit
but now my view objects that I dropped from the data control palette don't return any rows.
Any ideas?
Thanks,
Not sure what I did, but it started working!
