[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2292) Resources from resource servlet can't be re-rendered
Resources from resource servlet can't be re-rendered
----------------------------------------------------
Key: JBSEAM-2292
URL: http://jira.jboss.com/jira/browse/JBSEAM-2292
Project: JBoss Seam
Issue Type: Bug
Components: JSF
Reporter: Christian Bauer
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>
