return event in text fields

[Peter Dahm]

Hello,

we have this code sniplet in our page. This forces an event, if the value of
the textfield changes. 

<t:inputText styleClass="textfield" style="width:100%"
      value="#{directReportOverviewBean.filterNameAsString}"
    valueChangeListener="#{directReportOverviewBean.filterNameValueChange}">

      <a4j:support event="onchange" reRender="tblUebersicht" />

</t:inputText>


Know we have the need to force the same event on submitting the textfield
with the enter button. Unfortunately the current effect is, that one of the
buttons gets the submit event. 

Does someone of you have an idea to solve this problem ?
