Let me see if I have your use case correctly:
The user views the page, and some event triggers some Javascript code. The Javascript code needs to set the values of a hidden field, then submit the form, executing the action named Execute in the bindings.
First of all, get rid of the valueChangeListener. If you were to use a valueChangeListener, it would have to reference a method in a backing bean that takes a valueChangeEvent as its argument and returns void. Now try this - I haven't tried it myself, so I don't know that it will work, but I think it will. On your page:
<af:form id="theForm" defaultCommand="executeButton">
  <af:inputHidden id="startDate" value="#{bindings.Eventdate.inputValue}" />
  <af:commandButton id="executeButton"
                                actionListener="#{bindings.Execute.execute}"
                                text="Search"
                                disabled="#{!bindings.Execute.enabled}"
                                inlineStyle="display: none;" />
</af:form>And in your Javascript function:
document.theForm.submit();The basic idea is that the defaultCommand property of the form says that any submit of the form defaults to the button with the id=executeButton, unless some other button or link is explicitly clicked. The button has an inlineStyle with display none, which hides it from the user. Then the Javascript submits the form which ought to execute the default command.
