Refresh values of JSF page before validation occurs

Dear Rancher,

I am using JSF validation to simply check that the length of a field is 15, if not an error message is shown. My issue with this approach is
that user enters a number which is the correct length and clicks a button and some information is displayed about it. The second time when the user enters a number whose length is <15 then the validation error is shown BUT the information about the previous number remains on the screen.
My trouble is I am not sure how to do a refresh of the page.
I am doing validation like this:

Any ideas much appreciated.

Bind the inputText to an instance of HtmlInputText in a page bean.

Implement a ValueChangeListener (VCE). In the VCE, check the length. If the length is too long, you can change the value before rendering.

Of course, this might mess up your validation length tag, .
