Re : [SOLVED] How to use findAll() error param? Or how to show login form when login session is expired and user action calls can.Model.findAll()?

1. .fail( function( xhr ) {
   
2.   var obj;
   
3.   try {
4.     obj = can.parseJSON( xhr.responseText );
   
5.   } catch ( err ) {
6.     obj = {};
   
7.   }
8. })
   
9.  
   

That should do it, I think?

(If this is not a one-off, then you'll want to use some kind of base model that uses makeFindAll and its kin to set this up in a generic fashion. Have a look at the Caching data in local storage recipe to see how you should leverage these.)
