I\'m facing an application design problem with the Ext.data.Model
class in ExtJS. I will try to develop my ideas to a very common online
i fully agree with Molecular Man. By reading the ExtJS documenation it appeared more as evidence that this is a good route when you are making use of a tree set structure distributed to different stores. Frankly, this all could be true only if such association had in any way a reference of stores to make calls. That's not the case from what I have tested. Model associations don't have such relationship. Filtering is the best way to keep up with sequentially updating other grids whose models depend on others.
