back port fix from JBSEAM-2292-Resources from resource servlet can't be re-rendered
-----------------------------------------------------------------------------------

                 Key: JBSEAM-4619
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4619
             Project: Seam
          Issue Type: Bug
          Components: JSF Integration
            Reporter: Christian Bauer
            Assignee: Shane Bryzak
             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>
