Description

Titanium Mobile SDK 1.3.2, the ImageView.toBlob() function returns null (was working in 1.3.0).

        var imageView = Ti.UI.createImageView({
            width: 'auto',
            height: 'auto'
        });
        imageView.addEventListener('load', function()
            {
                var blob = imageView.toBlob();
                //  ^^^^ is null
            });
        imageView.image = pUrl;

The problem is in 1.3.3 too

If I use the (deprecated) url property instead of the image property it works. I believe the problem is here at ln 85 of TiUIImageViewProxy.m ( http://github.com/appcelerator/titanium_mobile/blob/master/iphone/Classes/TiUIImageViewProxy.m)"> http://github.com/appcelerator/titanium_mobile/blob/master/iphone/C...:
```
   
   83 -(id)toBlob:(id)args
   84 {
   85  id url = [self valueForKey:@"url"];
   86  if (url!=nil)
   87  {
   
```

Tested 1.6.0RC1 in KS (Base UI->Views->Image Views->Image Blob).

Incorrect test; tested independently of that (the KS test tests setting the image FROM a blob, not translating TO a blob - it's slightly misnamed).
