Enable file input in forms

[guest]

In dojo.formToObject file input fields are treated as non-value form elements. They should be treated as normal input fields.

To fix in dojo._base.xhr replace

var iq = "input[type!=file][type!=submit][type!=image][type!=reset][type!=button], select, textarea";

with

var iq = "input[type!=submit][type!=image][type!=reset][type!=button], select, textarea";

File inputs cannot be handled by XHR; you must use the iframe transport to post any kind of binary-encoded information (anything uploaded via a file input is handled by browsers as binary encoded, usually base64).

If you are assembling a file on the fly, you can use the DojoX xhrMultiPart transport (dojox.io.xhrMultiPart).
