SubTargets in custom group is empty

[blucobalto]

Hi,
I created a custom group.

var fabric.CustomGroup = fabric.util.createClass(fabric.Group, { type : 'CustomGroup', ... });

I added several items to the group (line, circle, group, rect ...).

I set subTargetCheck = true.

Problem:
when I click on the object (CustomGroup) subTargets is always empty.

In fabric.js (version: '2.0.2' line: 10109) I read the following code:

if (target.type === 'group' && target.subTargetCheck) {...
But target.type is equal to "CustomGroup".

Please, how can I solve this problem?
Thanks a lot,
Blu

That line must be changed in target instanceof fabric.Group

After have verified that it works on ie10
