How do I detect what was removed from File Picker?

I want a user to upload multiple files using the file picker (xls or zip files) and upload those as attachments to ArcGIS Server. How do I detect which file was removed if they click on the delete "x" on the file picker element? Am I missing something in the browser console that indicates this?

 

Thanks in advance!

  Hello Nelson,

   

  In order to do this, you will need to use the change event on the File Picker. If you add a Log to this event with this output: =$form1.state.filePicker1.value , you can see an array of the files that exist at the time of them being added. If you then compared the array of files ( =$form1.state.filePicker1.value.files[x].name or .type) from a previous input with those of the current input, then you could determine which file was removed.

   

  Thanks, Stefan
