I tried above code but it is giving error on media.getStreamData as
java.lang.NullPointerException "Attempt to invoke method getStreamData on null value"
why is it like this media is not null as it goes inside the if but media [ i ] is nulll....media length is 1 but media[ 0 ] is null
Please refer to this guide.
<button label="Upload" onClick="Fileupload.get(-1);" onUpload="processMedia(event.getMedias());"/>
