[alexrozario]

Hai, i am not successes when i am using from field with in modal panel
because when i submit the form the modal panel going to disappeared
i want it will be stable on when the form fields are not correct .

i have one more doubt, it is possible to invoke the modal panel when i click the commandButton?

i give my sample code here

<a href="javascript:Richfaces.showModalPanel('mp',{width:450, top:200})">Login</a>
 <rich:modalPanel id="mp" minHeight="200" minWidth="450" height="200" width="500" zindex="2000">
 <f:facet name="header">
 <h:outputText value="Login Form" />
 </f:facet>
 <f:facet name="controls">
 <a href="javascript:Richfaces.hideModalPanel('mp')">X</a>
 </f:facet>
 <h:form>
 <h:panelGrid columns="2" rowClasses="prop" columnClasses="name,value">
 <h:outputLabel for="username">Username</h:outputLabel>
 <h:inputText id="username" value="#{identity.username}"/>
 <h:outputLabel for="password">Password</h:outputLabel>
 <h:inputSecret id="password" value="#{identity.password}"/>
 <h:outputLabel for="rememberMe">Remember me</h:outputLabel>
 <h:selectBooleanCheckbox id="rememberMe" value="#{identity.rememberMe}"/>
 </h:panelGrid>
 <font color="red"><h:messages /></font>
 <h:commandButton value="Login" action="#{identity.login}"/>
 <h:commandButton value="cancel" onClick="javascript:Richfaces.hideModalPanel('mp')"/>
 </h:form>
 </rich:modalPanel>

1) http://labs.jboss.com/auth/wiki/ModalPanelValidation

2) yes you may use commandButton of type="button" and use onclick

[sergeysmirnov]

1.
add id="formpanel" for your h:panelGrid

2.
replace
<h:commandButton value="Login" action="#{identity.login}"/>
with
<a4j:commandButton value="Login" action="#{identity.login}" reRender="formpanel"/>

3.
important: be sure the navigation rule for #{identity.login} outcome has option

4.
replace:
<h:commandButton value="cancel" onClick="javascript:Richfaces.hideModalPanel('mp')"/>
with
<h:commandButton type="button" value="cancel" onClick="javascript:Richfaces.hideModalPanel('mp')"/>
