We just transitioned from using DocRaptor to our own installation of Prince, and discovered that some of our pdf conversions are missing Google Charts. This was previously accomplished by using the docraptorJavaScriptFinished() function, which would return true when the Google Charts were fully loaded. What is the correct way to accomplish this natively in Prince?

TIA

Maybe the 'complete' event?

Still hoping for an answer to my question.

DocRaptor supports its own JavaScript solution as well as that built into Prince, and the JavaScript in Prince runs synchronously until it completes, so if the Google Chart isn't rendering then there may be some other issue like an unsupported DOM interface. Are any errors or warnings appearing in the output log?

thanks for the reply. I turned on verbose logging, and I can see where the google charts scripts loaded successfully and everything, but there are no errors or warnings about it. The chart in my report simply doesn't get rendered as it does in DocRaptor.

Thanks, we are investigating this issue.

Have you found anything, Mike?

Sorry, we are still looking. There are some methods that need to be stubbed such as Object.freeze and Object.isFrozen, but even after that the main callback is not being called, so there must be some other issue with asynchronous code that we haven't found yet.

We've tracked down further issues and even got some pie charts to render but there are issues with sizing and labels getting cut off, so clearly more work remains to be done.

We are still working on this and making progress but due to the nature of the task it is impossible to give a timeframe for when Google Charts will work in its entirety; we will keep it on the roadmap and return with updates as we have them.
