Handling errors when document loading fails

[Søren Pedersen]

Hi

I can not catch the errors from document loading failure. I tried the suggestion from this thread

https://groups.google.com/forum/#!msg/pdfnet-webviewer/KYsQN4KmloQ/WoeQ2WRv35oJ

I have explicitly tried the SetErrorCallback like this:

partRetriever.SetErrorCallback(function(err) {
console.log('Hello from error callback!');
});

but the error is not caught.

The server responds with a HTTP 500, since the conversion fails and I get these traces in the Chrome console:

GET http://localhost:9082/TPTRWeb_war_exploded/resource/documents/xod/B8921582F9A59AEF 500 (Internal Server Error) CoreControls.js:348

_.extend.processData CoreControls.js:350

b.onreadystatechange CoreControls.js:348

I need to be able to present a decent error message to the user.

Any suggestions?

Hi,

From that error message it seems like you're using the streaming part retriever. Somewhat recently there was an error identified and fixed with the error callback for the streaming part retriever. You can download a build with the fix here: http://pdftron.com/ID-zJWLuhTffd3c/WebViewer/WebViewer_1.7.1.25192.zip
