Subject [jira] Created: (TOMAHAWK-1469) CAPTCHA renderer throws exception when session is missing
Date Tue, 08 Dec 2009 20:43:18 GMT
CAPTCHA renderer throws exception when session is missing
---------------------------------------------------------

                 Key: TOMAHAWK-1469
                 URL: https://issues.apache.org/jira/browse/TOMAHAWK-1469
             Project: MyFaces Tomahawk
          Issue Type: Bug
          Components: Captcha
    Affects Versions: 1.1.9
         Environment: Not relevant
            Reporter: Igor Spac


CAPTCHARenderer.renderCAPTCHA throws exception in case session is missing. This happens because
session attribute is set after the image being rendered. The fix would involve setting the
attribute before rendering the image.

Full stack trace:

java.lang.IllegalStateException: Cannot create a session after the response has been committed
