jsf - How to bind component inside rich:modalPanel -


i have problem rich:modalpanel , rich:calendar.

the code works without modal, when include components in modal recieve nullpointer in date.

working:

<a4j:outputpanel id="datepanel">     <a4j:region>         <rich:calendar id="calendar" value="#{ mybean.mydate }" />          <a4j:commandbutton value="confirm" rerender="tablepanel"             action="#{ mybean.addtotable }" />     </a4j:region> </a4j:outputpanel>

not working:

<rich:modalpanel id="mpcalendar" height="250" width="350" autosized="true"     zindex="1000">     <f:facet name="header">         <h:outputtext value="new date" />     </f:facet>     <f:facet name="controls">         <h:graphicimage value="/images/close.gif"             onclick="richfaces.hidemodalpanel('mpcalendar')"             style="cursor:pointer" />     </f:facet>     <a4j:outputpanel id="datepanel">         <a4j:region>             <rich:calendar id="calendar" value="#{ mybean.mydate }" />              <a4j:commandbutton value="confirm" rerender="tablepanel"                 action="#{ mybean.addtotable }" />         </a4j:region>     </a4j:outputpanel> </rich:modalpanel>

my questions are: 1. why when put inside modal doesnt work? 2. how can fix it?

i found wrong.

my modalpanel inside form... put modal outside form , added form modal.

example:

<a4j:outputpanel id="datepanel">     <a4j:form>         <rich:calendar id="calendar" value="#{ mybean.mydate }" />          <a4j:commandbutton value="confirm" rerender="tablepanel"             action="#{ mybean.addtotable }" />     </a4j:form> </a4j:outputpanel>  <h:form> ...
