JSF Datatable and SelectBooleanCheckBox -

-

i have scenario have give option user select applications , related profiles. user should select @ least 1 application , 1 profile , can select more one. each application has own profiles , there can multiple applications. userbean has list of applicationvo , applicationvo has isselected (boolean), application id (int), application name(string) , profile list. profile list has list of profilevo , profilevo has isselected(boolean), profile id(int) , profile name(string).

i new jsf , tried use datatable , selectbooleancheckbox works fine. @ point not sure how validate , display error message in same jsp remaining user entered data intact. not sure how update bean options checked/unchecked user.

when user clicks submit validations should be:

  1. at least 1 application should selected
  2. if application selected, @ least 1 profile should selected
  3. profile check boxes should disabled until application selected
  4. when user unchecks application check box, profiles check box should disabled.

i have following code. please me , can suggest me if there other best way accomplish same.

<h:datatable value="#{userbean.applicationlist}" var="applist">     <h:column>         <f:facet name="header">             <h:outputtext value="applications" />         </f:facet>         <h:selectbooleancheckbox value="#{applist.isselected}" label="#{applist.applicationname}"/>         <h:outputtext value="#{applist.applicationname}" />     </h:column>     <h:column>         <f:facet name="header" >             <h:outputtext value="profiles" />         </f:facet>         <h:datatable value="#{applist.profilelist}" var="profilelist">             <h:column>                 <h:selectbooleancheckbox value="#{profilelist.isselected}" />                 <h:outputtext value="#{profilelist.profilename}" />             </h:column>         </h:datatable>     </h:column> </h:datatable>
