> URL: https://jira.jboss.org/jira/browse/JBSEAM-2292
> Project: Seam
> Issue Type: Bug
> Components: JSF Integration
> Reporter: Christian Bauer

> Fix For: 2.2.1.CR1

> 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>
