    Default Answered: Ext.mixin.Observable v Ext.util.Observable

    The Observable mixin is fundamental to Ext JS classes.

    What the difference between these two implementations? Which one should I use?

  2. As far as the API goes, there should be parity (or very very close). The reason for having both is due to the merge of Ext/Touch code together. The core stuff uses mixin.Observable, however there were various things in Ext that made it not feasible to switch over in all cases.
