Dynamical changing HtmlInputText component style on failed validation...

Question

...but once validation passes the modified style isn't reset...and when navigating away from the page and then back again, the component will still have the modified style.
this is for JSF1.1 because i understand JSF1.2 has a errorStyle property.
I understand once first entry the components are rendered and then stored in a component tree for subsequent display, but because i have dynamical changed the style property it seems to be stored in the component tree.
here is snippets of my code
JSP page
<h:inputText id="textName" styleClass="inputText" *validator="#{fieldValidators.validateText}"* value="#{customer.name}" required="true">
<f:validateLength minimum="1" maximum="40"></f:validateLength>
</h:inputText>
_FieldValidators class_
public void validateText(FacesContext context, UIComponent toValidate, Object value)
((UIInput)toValidate).setValid(false);
*((HtmlInputText)toValidate).setStyleClass("inputText inputValidationError");*
FacesMessage message = new FacesMessage(errorMessage);
context.addMessage(toValidate.getClientId(context), message);
the style class +inputValidationError+ sets the outline of the input type to be red. so input components highlight in red when validation fails.
so to recap my issue, when the failed validation is corrected, the component still has the +inputValidationError+ style applied, and when navigating away from the page and back to it +inputValidationError+ still is in its style, so still appears with the red border.
any help or recommendations would be really welcome.
thanks.

Implement a PhaseListener which listens on the afterPhase of the RENDER_RESPONSE and get the clientId of all components which have a validation error by FacesContext#getClientIdsWithMessages() and put it in a HashSet or so. Then iterate recursively over all children of UIViewRoot and if it is an instance of UIInput, then (re)set the styleclass accordingly based on the presence of its clientId in the HashSet created before.
