Christoph Jäger commented on TAPESTRY-1508:
-------------------------------------------
I have the same problem trying to create a PNG (also from JFreeChart, but that
does not seem to be the problem), using Tapestry 5.0.7
In addition to the problem described above, I can not do a "Save image as" or
"Save page as" from my browser to save the image. Instead of the image, I get a
Tapestry Exception page with a stack trace like this:
* org.apache.tapestry.ioc.internal.util.TapestryException
* java.lang.NullPointerException

Is there some kind of work around for this?
> NPE on console after using StreamResponse with image/jpeg via jfreecharts
> -------------------------------------------------------------------------
>
> Key: TAPESTRY-1508
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1508
> Project: Tapestry
> Issue Type: Bug
> Affects Versions: 5.0.5
> Environment: Eclipse WTP 1.5.3, Tomcat 5.5.23, Tapestry 5.0.5
> SNAPSHOT, Maven, JfreeCharts 1.0.3 or 1.0.4
> Reporter: Daniel Jue
>
> I have a page that is similar to the pdfwritertestpage that was posted to the
> Tapestry User's list. Instead of returning a pdf, I am returning a context
> type "image/jpeg". I am using JFreeCharts 1.0.3 and this also occurs with
> 1.0.4.
> When I click on the submit button on the page, I DO get the image, and no
> visible errors in the browser. I see this error in my eclipse wtp console.
> The code that generates an image to an output stream has worked since
> Tapestry 4, so I hesitate to think the error is there.
