Help!A strange problem: a4j:form can not execute onsubmit when only one input included.


I put two inputtext in a4j:form and press enter key, it works correctly.
but if there's only one inputText in the a4j:form, one javascript error occurs:"Object required".


Here is the code that works:
--------------------------------------------------------------------
<a4j:form id="objectSearchForm" reRender="dataTable,pager" ajaxSubmit="true"
onsubmit="return isEnterKeyPressed();" styleClass="box">

<h:inputText styleClass="full_length" value="#{permissionSearchingAction.pageSize}"/>
<h:inputText styleClass="full_length" value="#{exampleObject4PermissionSearchingAction.englishName}"/>


<h:commandButton id="find" action="#{permissionSearchingAction.find}" value="Find"/>

...rich:datatable to show results
</a4j:form>
--------------------------------------------------------------------




Here is the code that does not work:
--------------------------------------------------------------------
<a4j:form id="objectSearchForm" reRender="dataTable,pager" ajaxSubmit="true"
onsubmit="return isEnterKeyPressed();" styleClass="box">

<h:inputText styleClass="full_length" value="#{permissionSearchingAction.pageSize}"/>



<h:commandButton id="find" action="#{permissionSearchingAction.find}" value="Find"/>

...rich:datatable to show results
</a4j:form>
--------------------------------------------------------------------



-----------------------used javascript:

function isEnterKeyPressed(){
if(event.keyCode==13){
return true;
}
}







I have tried
<a4j:form id="objectSearchForm" reRender="dataTable,pager" ajaxSubmit="true"
onsubmit="alert('a')" styleClass="box">

when i press enter key, it popup a alert dialog correctly.
Why the form cannot summit when there is only one inputText???
Why the form can DO summit when there are two more inputTexts???

Please help me! I have spent over 6 hours on it!

try to add <h:inputHidden or <h:inputText with style="display:none" :)

just a little remark : when you post code into the forum, you should put it into a code box : '&#91;code&#93;my code&#91;/code&#93;' so that it's more easy to read and it will not be filtered.
