How to invoke af:commandButton programmatically

Question

Hello everyone,
I have a page fragment with an af:commandButton that I have binded on a instance variable in a backing bean. I want to create a method that "push" the button. The button is not rendered.
public class MyBackingBean {
private RichCommandButton myButton;
public void pressResetFilterButton() {
ActionEvent actionEvent = new ActionEvent(myButton);
actionEvent.queue();
/* getter and setter here... */
<RegistrationConfigurator><handleError> Server Exception during PPR, #1
javax.el.ELException: java.lang.IllegalArgumentException: null source
     at javax.el.BeanELResolver.setValue(BeanELResolver.java:345)
     at weblogic.work.ExecuteThread.run(ExecuteThread.java:173)
Caused by: java.lang.IllegalArgumentException: null source
     at java.util.EventObject.<init>(EventObject.java:38)
     at javax.faces.event.FacesEvent.<init>(FacesEvent.java:72)
     at javax.faces.event.ActionEvent.<init>(ActionEvent.java:69)
     at [first row of pressResetFilterButton method]
How can I click on myButton? I use JDeveloper 11.1.1.3.0
Thanks in advance.

Thanks for your responses.
@John
With rendered = true I have the same error (visibility both true or false).

Yes, I have an exposed method from a ViewObjectImpl (that should be reset the filter in a af:table)
public void clearOutstandingImplicitViewCriteria() {     
// we only want to remove the stuff that was added though the table
//filter (or a default search form)
// "__ImplicitViewCriteria__" is the magic name for this VC
ViewCriteria vcDefault = this.getViewCriteria(ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);
if (vcDefault != null) {
//Clear the stored values
vcDefault.clear();
//And refresh the collection
this.executeQuery();

I cannot to do this since the method is in the VOImpl class. See above.
For recapping: I would to reset the filters in an af:table. I'm following this source: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/april2012-otn-harvest-1609383.pdf (pp. 9-11)
I have binded the table in the same backing bean written before. Here the entire class:
public class MyBackingBean {
private RichTable empTable;
private RichCommandButton resetButton;
public MyBackingBean() {
public void setEmpTable(RichTable empTable) {
this.empTable = empTable;
resetTableFilter();
public RichTable getEmpTable() {
return empTable;
public void resetTableFilter() {
FilterableQueryDescriptor queryDescriptor = (FilterableQueryDescriptor) getEmpTable().getFilterModel();
if (queryDescriptor != null && queryDescriptor.getFilterCriteria() != null) {
queryDescriptor.getFilterCriteria().clear();
// PPR refresh a jsf component
AdfFacesContext.getCurrentInstance().addPartialTarget(getEmpTable());
public void setResetButton(RichCommandButton resetButton) {
this.resetButton = resetButton;
public RichCommandButton getResetButton() {
return resetButton;
public void pressResetFilterButton() {
ActionEvent actionEvent = new ActionEvent(resetButton);
actionEvent.queue();
I put the call to pressResetFilterButton method in the resetTableFilter method. In this way I got the previous error. The reason why I want to programmatically click the button is to perform the step on page 11 automatically.
Thank you again.
