TypeError: 'undefined' is not an object (evaluating 'h.substring') when loading store
REQUIRED INFORMATION

Architect Build tested:
- Build: 678
Project Type:
- Touch 2.1.x
Description:
- Architect throws an error when using a store with a DataView with a custom DataItem.
Steps to reproduce the problem:
- Create a model and store named 'store1' that properly loads data, set autoLoad to true. Right click store and click 'Load Data'
- Create a DataItem with alias 'dataitem' with proper style with a child component that has a proper tpl
- Create a DataView and check useComponents, defaultType to 'dataitem', and store to 'store1'
- Click on different views in the Project Inspector to load and reload the CSS for the DataView
The result that was expected:
- Loading of the store in Architect with the proper layout of DataItems and CSS in the view
The result that occurs instead:
- Window saying that an error occured:
  
  Code:

I'd be very interested in at least a reasonable workaround for this bug.

Easiest thing would be to not autoload the store while in Sencha Architect.

Looks like you can't load the store at all while in Architect.

I can confirm that the attached project throws an error even in our latest development build.

In a brief cursory look at this it looks like what's happening is that the default list item dependencies is not being taken into account. Ie we have to create teh defaultType class before trying to load the store (otherwise it won't know what to paint)
