in this version we take care also of the rejected types issue.
Case 1): all uploaded files are of rejected types -> it works
Case 2): all uploaded files are of accepted types -> it works
Case 3): uploaded files are mixed (rejected and accepted) types --> it works in history list, but it will also upload all files at bean-side. Need to investigate on that.
