I have absolutely no idea why what I did has resolved this issue, but I'll
post what I did because perhaps it will help someone that will face the same
problem.
I was creating my input files dynamically, using document.createElement().
after create them, I put them in a div, and after render the div, I pass the
inputs to the method FileSubbmiter.captureFile() one by one, to capture the
files. It didn't work on I.E, only in firefox, so, after lots of tests,
comes to me a divine light and even with no reason, I stopped of creating
inputs by document.createElement and just wrote the HTML code on innerHTML
property of the div that I was rendering the inputs. Now everything is fine
in I.E and also in Firefox. bellow I'll show, first the code of creation of
inputs that doesn't work and after the code that works:
1 - doesn't work:
divFile = document.createElement('DIV');
var inputFile = document.createElement("INPUT");
inputFile.id = "inputFile_"+id_border+"_"+countDivFiles;
inputFile.type = 'file';
inputFile.name='file_'+countDivFiles;
divFile.appendChild(inputFile);
2 - works:
divFile = document.createElement('DIV');
divFile.innerHTML = "<input type='file'
id='"+"inputFile_"+id_border+"_"+countDivFiles+"'
name='file_"+countDivFiles+"'>";
as I said, I don't know why the captureFile in I.E doesn't work when I pass
the input file created by the first step, but, it doesn't.
