I'm trying to adapt a custom image cropper Dojo widget for Optimizely CMS 12. Images can be added to the widget by selecting through a button click and subsequently selecting the image from the assets, or by drag-and-drop.
When the image is added to the widget through drag-and-drop the onChange event reaches the back-end, and the page can be saved.
When adding the image through selection the onChange event is fired but the back-end is not notified. Also, just changing the crop dimensions does fire the onChange event, without reaching the back-end.
This is the code which is called in all scenario's:
_setValue: function (value) {
this._set('value', value);
this.onChange(value);
this._updateDisplayNode(value);
this.validate();
}Why would onChange work with drag-and-drop and not in the other cases? Is something more necessary to enable the onChange event to reach the back-end. The value passed is the same in all scenario's.
