XML Forms Combobox entries are disappearing after validation error

Question

In my XMLForm I have a combobox which is filled with items from a property. After submitting the form (when saving) with a validation error (e.g. date invalid) the entires in the combobox disappear and the entry can be saved without an entry (can this be permitted?).
Also, when opening the saved entry, the combobox is also empty. I think this is a (unpatched?) KM/XMLForms bug, but maybe there a patch or an other solution for this?
Is it possible the fill the combobox with fixed entries (without using the property)

Answer 1

ok, fixed it with the following :
<ice:selectOneMenu id="chosenSystem" value="#{userRoles.selectedSystem}"
                   valueChangeListener="#{userRoles.systemValueChanged}"
                   immediate="true" partialSubmit="true" required="true"
                   requiredMessage="#{fv_msg.ursysmandatory}" >
    <f:selectItem itemLabel="Choisissez un truc" itemValue=""/>
    <f:selectItems value="#{userRoles.remoteSystemItems}"/>                    
</ice:selectOneMenu>
<ice:selectOneMenu id="chosenAbstraction" value="#{userRoles.userRole.abstraction}"
                   converter="remoteAbstractionConverter" >
    <f:selectItem itemLabel="Choisissez un truc" itemValue=""/>
    <f:selectItems binding="#{userRoles.remoteAbstractionsHtml}"/>
</ice:selectOneMenu>The valuechangelistener simply updates the binded component in chosenabstraction.
Any idea on how to do that with ajax?
