Sencha Touch 1.1 - CRUD actions & callbacks via REST proxy

CRUD actions
Methods without value param (update, destroy):
store.update({
    callback: function(answer, object, success) {
        if (success) { ... }
    }
});

store.destroy({
    callback: function(answer, object, success) {
        if (success) { ... }
    }
});


Methods with value param (create, load):
store.create(values, {
    callback: function(answer, object, success) {
        if (success) { ... }
    }
});

store.load({
    callback: function(answer, object, success) {
        if (success) { ... }
    }
});


CRUD action executes only once?
If you can run some of these functions once and after that no XHR is made, it may be because you encountered this bug: Bug @ Sencha Forum

I solved this bug by setting store.snapshot to false, so the function that engages the XHR is no longer looking for changes in the snapshot but in the store object.
