I have a Seam/Richfaces(3.3.1) application.

On one of my pages I have a button, that opens a modalPanel.

On that modal panel I have a rich:Calendar element that's pre-populated with the current date. The element is mandatory, i.e the user has to accept the prepopulated date or select a new valid date.

The problem I have with this is that if the user deletes the value in the field, closes the modalPanel and then opens that panel again, after the calendar field is again populated with the current date, the requiredMessage text dissapears from the panel, but the field is still shown in red. As if the validation worked, but, figuratevely speaking,  the rendering stopped in the middle.

Here's the code:

page.xhtml

<ui:define name="body" >
 
 <h:form id="ttform" styleClass="edit" >
 <h:panelGrid columns="1" columnClasses="rich-panel-button-left">
     <s:div >
   <a:commandButton id="btnShow" value="Show" reRender="divPanel"
     onclick="Richfaces.showModalPanel('mpDate');" />
   </s:div>
 </h:panelGrid>
 </h:form>
 <a:log popup="true" level="ALL" style="width: 800px; height: 300px;" rendered="true" />

I attached the log output and also a screenshot of the modal panel after it's been re-opened.

I'm probably missing something here, but can't find what is it.

Any ideas?
