Clearing the stale messages from the previous request on client side validation error

While going through a specific use case, I came to know that ADF Faces run time does not auto clear the messages added to the page from the previous request. This indeed is the expected behavior as of now. I'm sure many of you know this already, however thought of posting this for the benefit of developers who has not worked on such scenarios before, like me;).

The side effect of this implementation is that, once you displayed any message to the end user by adding a FeacesMessage to a FacesConetxt from an event handler method and if the next immediadte action from the end user result in anay client side validation error, you may get the previous message and the newly generated validation error in the message window as shown in the following screen shot.

Let me discuss a work around solution for such use cases. Its simple, add a af:clientListener to the UI component to clear the messages by calling ADF Fcaes JavaScript API AdfPage.PAGE.clearMessages(componentId);.
 <af:commandButton text="Save with Clearing Prev Message"   
      id="cb2" actionListener="#{TestBean.saveAction}"  
      <af:clientListener method="clearGlobalMessage" type="click"/>  
 <af:resource type="javascript">  
  function clearGlobalMessage() {  


I'm attaching a very simple example illustrating the above solution. You can download the sample workspace from here.
[Built using Oracle JDeveloper]

How to run this sample?

Run test.jspx, key in some values in the input field and click save button. You may see information message. If you click save button again, validation error message alone appears.The previous INFO message is cleared using javascript method clearGlobalMessage()

Please note that, the above case will be addressed in future releases in a much better way. In fact there is an enhancement request for the same, be happy :)


  1. Hi,

    Is there a way to customize the default validation popup?
    Like, remove the hyperlink for the mandatory fields, etc.?
