How to show error message on dropzone when file upload is not valid?

Hi Everybody,

When I set my nuxeo-dropzone element and restrict it to pdf file type, I want to be able to display an error message that it cannot load the file.

It fails silently if you upload a type that's not accepted.


    <nuxeo-dropzone document="{{document}}" xpath="myDoc:myPath" label="File Example" accept=".pdf" required="true" ></nuxeo-dropzone>

Is it possible to catch the event and show an error message?
