NPE s:validateEquality with readonly fields
Hi, I have a problem with s:validateEquality and readonly h:inputText, this is the sample code:
<a4j:region>
<s:decorate id="creditValueFieldId" template="/layout/edit.xhtml">
<ui:define name="label"><h:outputText value="#{messages['UserMovement.credit']}"/></ui:define>
<h:inputText id="creditValueId" required="true" value="#{userMovement.credit}" readonly="true" />
</s:decorate>
<s:decorate id="valueFieldId" template="/layout/edit.xhtml">
<ui:define name="label"><h:outputText value="#{messages['UserMovement.value']}"/></ui:define>
<h:inputText id="valueId" required="true" value="#{userMovement.value}">
<s:validateEquality for="creditValueId" operator="less_or_equal" message="#{messages['Withdraw.not_enough_credit']}" />
<a4j:support event="onchange" eventsQueue="default" reRender="valueFieldId,withdrawId"/>
</h:inputText>
<ui:param name="description" value="#{messages['Withdraw.value_must_be_le_credit']}" />
</s:decorate>
</a4j:region>When I change the value (onchange event on creditValueId) I get this exception:

The courious thing is that when I remove the readonly mark in the first field (creditValueFieldId) the exception dissapears :). That is:
<h:inputText id="creditValueId" required="true" value="#{userMovement.credit}" />Any idea ?
