Class ValidateBean

java.lang.Object
  javax.faces.view.facelets.TagHandler
      org.omnifaces.taghandler.ValidateBean

All Implemented Interfaces:

javax.faces.view.facelets.FaceletHandler

public class ValidateBean
extends javax.faces.view.facelets.TagHandler

The <o:validateBean> allows the developer to control bean validation on a per-UICommand or UIInput component basis. The standard <f:validateBean> only allows that on a per-form or a per-request basis (by using multiple tags and conditional EL expressions in its attributes) which may end up in boilerplate code.

Usage examples:

 <h:commandButton value="submit" action="#{bean.submit}">
     <o:validateBean validationGroups="javax.validation.groups.Default,com.example.MyGroup"/>
 </h:commandButton>
 

 <h:selectOneMenu value="#{bean.selectedItem}">
     <f:selectItems value="#{bean.availableItems}"
     <o:validateBean disabled="true" />
     <f:ajax execute="@form" listener="#{bean.itemChanged}" render="@form" />
 </h:commandButton>
