Valuechangeevent fired, but no value was changed

Question

Hi there,
i got a form with a selectonemenu that has a valuechangelistener attached.
problem: when i press my submit button the valueChangeEvent is fired though i didnt change the value of the selectOneMenu before.
Cause the listener method skips further phases by renderResponse() the submitAction isnt executed.
When i click the button again all works as expected.
Any pointers how to get rid of this behaviour? Do i have to submit the form onload() or sth? how is this done best?
<h:form>
<h:selectOneMenu
  value="#{bean.testMenuSelection}"       
  valueChangeListener="#{bean.listener}"
  onchange="submit()" immediate="true">
  <f:selectItems value="#{bean.menuSelectItems}" />
</h:selectOneMenu>
<t:commandButton
  value="Submit"
  action="#{bean.submitAction}" />
</h:form>

Thx, but this doesnt solve my problem.
I only got this trouble when i first load the form. It seems that with the initial filling of the selectOneMenu a changeEvent occures which is fired when i submit the form with my button. renderResponse() in the listener prevents the button-action to be executed. I understand this. WHat i dont understand is, is why the changeEvent is fired at all when i didnt cahnge the value.
Later when i REALLY change the value all works fine. If i press the button after having changed the value of the menu the button action is executed as expected.
