When generating a process instance diagram by ProcessDiagramGenerator, the result image is somehow cropped and doesn't show all content in the process. You can find more in attachment. And just ignore those "square" block due to non-English character, I'm fine with that.
Well…I can't upload image, it says 'Could not upload attachment to ./files/1731_1188b8c949ffe2561e7635e2c6b17525.' I'll try it later.
