Nullpointerexception throws when inserting entity using Auto-generated Classendpoint insert method

Question

I am confused to using auto-generated endpoint class. I want to use generated endpoint to insert new object into datastore. But, an exception is throwing.

Answer 1

I was having the same exact problem after using the Eclipse Plugin to autogenerate the cloud endpoints (by selecting "Google > Generate Cloud Endpoint Class").

Following your advice, I added:

if(foo.getID() == null) // replace foo with the name of your own object return false;

The problem was solved.

How is that Google hasn't updated the autogenerated code yet as this must be a highly recurring issue?

Thanks for the solution.
