Hello all,

I am new to using Sencha (and Sencha Architect) and have so far developed the following:

1.A php form that retrieves MySQL data and encodes it as JSON.
2. A Store, AJAX Proxy and JSON Reader that retrieves the JSON string.
3. An app that populates a list from the above Store.

However I need to be able to select data from a second JSON string where a field matches the selection of the first list. The only way I can see to do this is to post the list selection to a php form which will then run a mySQL query based upon the selection. I have tried many different ways and read lots of other forum posts but cannot seem to do this in Sencha Architect.

The app would also need to refresh the second store when a selection is made.

Any help or guidance would be very much appreciated.
