Hello,
I was using rich:calendar recently and as value for datePattern I used some entry from messages.properties file.
There is a problem however. While the dates are shown properly, the internal validation of the date fails.
This is a snippet of the page:
<g3:label value="#{msg.orm_prescription_dialog_period_lblDateStart}:"
id="lblDateStart" for="calStart"></g3:label>
<h:panelGrid columns="2"
columnClasses="g3_calendar_container, g3_error_message">
<rich:calendar id="calStart" value="#{editOrderBB.date}"
datePattern="dd.MM.yyyy HH:mm">
<a4j:support event="ondateselected"
onsubmit="#{rich:element('formChanged')}.value = 'change';return false;" />
</rich:calendar>
<h:message id="calStart_message" for="calStart" />
</h:panelGrid>
<g3:label value="#{msg.orm_prescription_dialog_period_lblEnd}:"
id="lblEnd" for="calEnd"></g3:label>
<h:panelGrid columns="2"
columnClasses="g3_calendar_container, g3_error_message">
<rich:calendar id="calEnd" value="#{editOrderBB.dateTo}"
datePattern="#{loc['datetimePattern_common']}">
<a4j:support event="ondateselected"
onsubmit="#{rich:element('formChanged')}.value = 'change';return false;" />
</rich:calendar>
<h:message id="calEnd_message" for="calEnd" />
</h:panelGrid>
did you registered your messages file with a4j:loadBundle?
