this.options never deleted

[schaef]

If you store some data in your widget with this._setData('test', largeJson); and than remove your widget from DOM, the largeJson will not be removed by the default destroy method. It stays until a page refresh in the memory.

If I add the line delete this.options; in the default destroy method in ui.core.js the 'real' object is removed from memory. It seems to me that jQuery.cache.id.widgetname.options.test is only a reference to the place of the object 'largeJson'. And that only the reference is deleted by default, not the value itself.

Are you suggesting to add delete this.options in the destroy methods?

I wonder if a proper GC shouldn't clean this up once there is no reference left to the widget instance. Maybe a instance reference still exists and we should actually clean that up.

The _setData method no longer exists. Can you check whether this problem still exists in the most recent version?

[Scott González]

This sounds like you're keeping a reference to the data yourself somewhere else.
