[FIXED-129][Ext 3.0.3] Form upload: hidden iframe not hidden in FF

[Stefan B]

When submitting a form with a {fileUpload: true} configuration, Ext temporarily creates an iframe, adds an HTML form and performs a standard submit on it.

The temporary iframe should not be visible, so Ext adds a class "x-hidden" to it. This is done with the following code in Ext.data.Connection#doFormUpload:

Ext.fly(frame).set({
    id: id,
    name: id,
    className: 'x-hidden',
    src: Ext.SSL_SECURE_URL // for IE
});

In FF (3.5.5 in my case) setting the class via Element.set({className: "..."}) fails and results in the following HTML, causing the iframe to stay visible during its lifetime:

<iframe id="ext-genXXX" name="ext-genXXX" classname="x-hidden" src="blank.html">

Tested on IE7 also, no problem there.

Thanks for looking into this,
Stefan

Should be

Ext.fly(frame).set({
    id: id,
    name: id,
    className: 'x-hidden',
    src: Ext.SSL_SECURE_URL // for IE
}, false);

IMHO it should be:

Ext.fly(frame).set({
    id: id,
    name: id,
    cls: 'x-hidden' // fixed in Core rev. 70
});
doc.body.appendChild(frame);
Ext.fly(frame).set({
    src: Ext.SSL_SECURE_URL // for IE and Opera 10
});

Fixed in Core-SVN for 3.x.
