Dear Davit,
thanks to your latest improvements on Plupload2, I was able to replace Plupload 1.5.6 by current version of Plupload2.
So I am working on this approach.
I have set up two instances of Plupload: A main one and the second (arbitrary) one, from which I want to feed files added later on to the main plupload instance.
I am trying to do this in the QueueChanged handler:
var onQueueChanged = function(uploaderArbitrary){
this.mainUploader.addFile(uploaderArbitrary.files);
};
Unfortunately no files are added to the mainUploader instance, which also means no QueueChanged or FilesAdded events for this instance get fired.
uploaderArbitrary.files seems to look well:

Is there maybe some configuration I am missing?
Also
this.mainUploader.addFile(uploaderArbitrary.files[0]);
doesn't have an effet...
Thanks for your help,
Sascha.
