Hello,

I'm using Ext Designer 1.2.2 with Ext JS 3. I successfully export the project, but when I try to run it I receive:
Code:
Uncaught TypeError: Cannot call method 'on' of undefined
I dig a little into the generated code and here is what I found:
The problem is in the following code:
Code:
store = Ext.StoreMgr.lookup(store);
            store.on({
                scope: this,
                beforeload: this.beforeLoad,
                load: this.onLoad,
                exception: this.onLoadError
            });
I.e. here "store" returned by the StoreMgr is not defined and of course we can't access its method "on". It is not defined because it is missing in StoreMgr. So, I started to search where we add things inside the StoreMgr and found that this is happening in the constructor of Ext.data.Store by using
Code:
Ext.StoreMgr.register(this);
So far so good ... it is clear for me that once the "store" is created register itself in that store manager. I simply put a console.log in the very first line of the constructor of the store and that log never occur. It looks like there is no any initial store creation. In other words I need a "store" object before it is created.
In my case I have a PagingToolbar with a store set and when that component needs it the store is still not created.

So, my questions is: can you give me any advice how to fix the problem or just any direction of the Stores' things. I.e. how are they created, initialized etc ...
