Hi Nicolas,

I'm experiencing the following exception when trying to render a PDF: play.exceptions.UnexpectedException: Unexpected Error at play.modules.pdf.RenderPDFTemplate.apply(RenderPDFTemplate.java:102) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:252) at Invocation.HTTP Request(Play!)

I believe this issue is more to do with the Flying Saucer transformer then the play-pdf plugin. In fact I think it is this issue which is fixed by this pull request. I'm trying to work out how I get this fix all the way back in to my play app. Is it the case that the Flying Saucer transformer is included via the YaHP project? So will I have to update and build Flying Saucer, then YaHP and then play-pdf? Any assistance appreciated.

cheers, Chris

Hi @tazmaniax

did you find a way to fix this issue? I'm also encountering this issue. I tried updating the 3rd party libs but it doesn't work.

This fix https://github.com/philcali/flyingsaucer/commit/e653850a67b06a08364030a51e5ae4a855213016 with rebuilt jar actually solves the problem.
