Multiple JsonReaders reading different sections of JsonStore's data

[el.nino]

hi guys,

say i have a json string like this:

{"Staff":[{"id":1,"name":"John"},{"id":2,"name":"Mary"},{"id":3,"name":"Sandra"}],"Students":[{"id":2,"name":"Peter"},{"id":3,"name":"Carl"},{"id":4,"name":"Hodges"}]}

(Note: If you want to see a better formatted json string please paste it on http://json.parser.online.fr/)

And I have two comboboxes cmbStaff and cmbStudents. is it possible to bind both comoboxes to the same store but having different jsonreaders? i.e. cmbStaff's datareader would read the string with root: 'Staff' and cmbStudent will read the string with root 'Students'?

This is to save the amount of AJAX gets being made by the store and having a different store for every comboBox (imagine if my form had 20 comboboxes!).

Any ideas? Feel free to inform me if you need any more information Thanks!

The way I've handled this exact scenario before is to make a single AJAX request for all my data. Then setup a store per combobox pointing to the appropriate "root" location for each store. You'll save server requests. It's ok to have a store per combo. The current design of the JsonStore only supports 1 reader.

store1.load({
  callback: function(){
    store2.loadData(store1.reader.jsonData);
    store3.loadData(store1.reader.jsonData);
    store4.loadData(store1.reader.jsonData);
    store5.loadData(store1.reader.jsonData);
  }
});
