In my Lightning component a list of Custom Object records are fetched and being displayed on the component. After editing some of the records and sending back the same list to the Update function in apex controller. The call is not getting initiated. It is throwing some error "Unable to read sObject" in the browser console.
The type of return value in first function to get records, type of attribute in component, and the type of parameter in Apex update function are all the same (custom object). Name-space also is added as required.
The same code was working perfectly before Spring '16 release. Any thoughts are welcome.
