Using Memory proxy for a store with an array of data

[lcurrens]

I'm having difficulty working with data stores that are not reading JSON data (as in the examples).

I have an array of data in memory. It will look something like this:

[{
PROP1: 'val1',
PROP2: 'val2'
},
{ PROP1: 'val3',
PROP2: 'val4'
}]

I want to attach this data to a store, then set that store on a List. I'm having some difficulty with this.
I have tried creating a store with a Memory proxy and an Array reader.

Do I need fields on the store to match "PROP1" and "PROP2"? Or should I set a model on the store?

Is there an example of using a memory proxy somewhere? What about XML reader examples?

Yes you need 2 fields here PROP1, PROP2
