Displaying message when rich:calendar value is in wrong form

[leelavathic]

I have given the rich:calendar in my code as editable which means user can enter any data. When I click on the submit button, the incorrect value gets cleared off and page doesn't get submitted as expected. But no user friendly error message is displayed.

I tried both richfaces 3.1.3 and 3.2.1.

I need to display a message when date format is incorrect.

<rich:calendar id="startDate" resetTimeOnDateSelect="true" converterMessage="WRONG FORMAT" enableManualInput="true" datePattern="MMM dd yyyy, HH:mm" >
