> Found this after using the captcha:
>             <div class="input">
>                 <a:region>
>                     <s:validateAll>
>                         <h:graphicImage value="/seam/resource/captcha" style="vertical-align:text-bottom;"/>
>                         <h:inputText tabindex="1" size="6" maxlength="6" required="true" id="verifyCaptcha" value="#{captcha.response}">
>                             <a:support status="#{statusId}" event="onblur" reRender="verifyCaptchaEntry"/>
>                         </h:inputText>
>                     </s:validateAll>
>                 </a:region>
>             </div>
> This is a re-rendered s:decorate form field, so that onblur we get a new challenge (if the captcha repsonse was wrong). However, the graphicImage is not reloaded from the server, the browser caches it. To prevent browser caching, this is a quick hack:
>             <div class="input">
>                 <a:region>
>                     <s:validateAll>
>                         <h:graphicImage value="/seam/resource/captcha?nocache=#{wiki:generateRandomNumber()}" style="vertical-align:text-bottom;"/>
>                         <h:inputText tabindex="1" size="6" maxlength="6" required="true" id="verifyCaptcha" value="#{captcha.response}">
>                             <a:support status="#{statusId}" event="onblur" reRender="verifyCaptchaEntry"/>
>                         </h:inputText>
>                     </s:validateAll>
>                 </a:region>
>             </div>
