Component ace:dateTimeEntry seems to be not working for JBoss 7.1.1. app server.
We use it this way:
<icecore:config mandatoryResource="dateTimeEntry"/>
<ace:dateTimeEntry id="passwordExpiration"
                   locale="en"
                   renderAsPopup="true"
                   label="label"
                   pattern="MM/dd/yyyy"
                   styleClass="dateInput styleClass"
                   value="#{UsersBean.selectedUser.pwdExpirationDate}"
                   disabled="false"
                   navigator="true">
    <ace:ajax execute="@this" render="@this" event="dateTextChange" onStart="alert(1)" onError="alert(2)"/>
    <ace:ajax execute="@this" render="@this" event="dateSelect" onStart="alert(1)" onError="alert(2)"/>
</ace:dateTimeEntry>

The problem is thet the ajax request is not send neither on blur event nor on click calendar by mouse. No network activity at all. Moreover, no alert is shown. It means that javascript handlers onStart and onError are not called too. No javascript errors in browser logs. Calendar popup is displayed properly.
On Glassfish 3.1.1 it works perfectly.
