Class IgnoreValidationFailed

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

All Implemented Interfaces:

javax.faces.view.facelets.FaceletHandler

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

The <o:ignoreValidationFailed> allows the developer to ignore validation failures when executing an UICommand action. This taghandler must be placed inside an UICommand component and the parent UIForm must be an <o:form>. When executing an ajax action, make sure that the parent UIForm is also included in the <f:ajax execute>.

For example:

 <o:form>
   ...
   <h:commandButton value="save valid data" action="#{bean.saveValidData}">
     <o:ignoreValidationFailed />
     <f:ajax execute="@form" />
   </h:commandButton>
 </o:form>
 

Note that the model values will (obviously) only be updated for components which have actually passed the validation. Also the validation messages will still be displayed. If you prefer to not display them, then you'd need to exclude them from rendering by <f:ajax render>, or to put a proper condition in the rendered attribute.
