Detecting validation errors

Question

Hi,
how can I detect a validation error?
For example, I'd like to show a generic message at the top of a page which says:
"Some errors are detected, please check your data"
This message is not bounded to a particular field, in fact I can use the <h:message for=""/> tags for showing the errors generated by each field.
The only one solution I found is adding ugly code to my JSP:
<% if (javax.faces.context.FacesContext.getCurrentInstance().getMessages().hasNext()) { %>
              <span style="color: red;">Some errors are detected, please check your data</span>
            <%}The only one way to detect a validation error is cheking the message queue. If it's empty, no validation errors occured.
I don't like it.
Some help?

I would like to share the kind of approach I had used with the same situation.
You can put one "h:outputText" at the top of the page for displaying all the error messages.Obviously attach it to some backing bean property.
Now whenever you encounter any error just assign your customize message to this bean propery.
Whenever the response is rendered you can see your error message being displayed at the top of the page.
Funny ! but it works !!!!
