Disable custom validator during page load

I have a custom validator on a JSF page and i am using view param to set the value of callbackUrl intothe Backing Bean which is received in the URL.

For example, 

http://localhost:8080/myapp/index.jsf?callbackUrl=google.com

The JSF:

<f:metadata>
    <f:viewParam id="callbackUrl" name="callbackUrl"
        value="#{userbean.callbackUrl}">
        <f:validator validatorId="com.me.something.CallbackUrlValidator" />
    </f:viewParam>
</f:metadata>

I have a custom validator that checks the URL whether this is valid. The custom validator executes once during page load and once during page submit. I would like only the validator to kick in only during page submit. Is there anyway i can do this?

The <f:validator> tag has a disabled attribute for the very purpose.

To check whether the current request is a postback (a form submit), just check FacesContext#isPostback().

<f:validator ... disabled="#{not facesContext.postback}" />
