Jarek Lipski commented on STS-527:
----------------------------------
I think this bug still exists in newest stripes 1.5rc1. The exception is thrown
when error message is displayed on the page inside <stripes:errors/> tag.
Here's my exception handler code (not finished, I know that I shouldn't return
null at the end):
public Resolution handle(Exception exception, HttpServletRequest
request,
HttpServletResponse response) {
logger.warn("Exception. Message: " + exception.getMessage(),
exception);
ActionBean action = (ActionBean)request.getAttribute(
StripesConstants.REQ_ATTR_ACTION_BEAN);
if (action != null)
{
action.getContext().getValidationErrors().addGlobalError(
new
LocalizableError("myproject.myerror.exception"));
return action.getContext().getSourcePageResolution();
}
return null;
}
Here's part of the stacktrace:
java.lang.NullPointerException
at
net.sourceforge.stripes.validation.LocalizableError.getMessageTemplate(LocalizableError.java:91)
at
net.sourceforge.stripes.action.SimpleMessage.getMessage(SimpleMessage.java:91)
at
net.sourceforge.stripes.validation.SimpleError.getMessage(SimpleError.java:102)
at net.sourceforge.stripes.tag.ErrorsTag.doEndTag(ErrorsTag.java:349)
Looks like first line in LocalizableError.getMessageTemplate is causing
problems, because beanclass is null.
String template = LocalizationUtility.getErrorMessage(locale,
getBeanclass().getName() + "." + messageKey);
> NPE when using LocalizableError in AutoExceptionHandler

> Project: Stripes
> Issue Type: Bug
> Components: ActionBean Dispatching
> Affects Versions: Release 1.5
> Reporter: Frederic Daoud
> Assignee: Frederic Daoud
> Fix For: Release 1.5
>
>
> When using a LocalizableError in AutoExceptionHandler, a NPE is thrown
> because of trying to access the beanclass, which has not been set at this
> point.
> More details: http://permalink.gmane.org/gmane.comp.java.stripes.user/7225
> Using beanclass was introduced in Stripes 1.5, so this is a bug.
> The fix is to guard against null and move on to other keys for localizable
> errors.
