pe:documentViewer TypeError: window.parent.PrimeFacesExt is undefined

fcanevar commented 9 years ago

I've a web-app MyFaces 2.2.7, PF 5.1.16 and PFext 3.0 and I'm trying to update it to PF 5.2.6 and PFext 3.2 .

Every time that I dynamically open a p:dialog with a pe:documentViewer inside I get this error in the Firefox console: "TypeError: window.parent.PrimeFacesExt is undefined" and I can't see the embedded PDF, if I refresh the page and reopen the dialog that I can see it...

Please post a complete example (xhtml + bean), otherwise it will be closed.

@francesco-strazzullo Could you please check it? If you can't replicate, just close it as the user didn't provide a example.

Sorry, I've lost track of the ticket, I'll provide an example today

Sorry again for the delay and thank you very much. Here it is the example: index.xhtml

As you can see, if you don't uncomment the last line in the index.xhtml page you'll get always that error, otherwise you'll see the correct content.

Thanks a lot, Fabio

Ok Thanks i will look into it!

pe:documentViewer is included via a dynamic include, so the component is not available when building the view. This can't be fixed on our side. See: http://blog.primefaces.org/?p=1503

You need always to include primefaces extensions.js via:

primefaces-extensions / primefaces-extensions.github.com

pe:documentViewer TypeError: window.parent.PrimeFacesExt is undefined #343
