[jboss-user] [EJB 3.0] - Re: javax.persistence.EntityNotFoundException: deleted entit

[misterpea]

My colleague found a solution, but first of all an amendment ...

In my company bean I had:


  | 	@OneToMany(cascade = CascadeType.ALL,
  | 			   mappedBy = "company",
  | 			   fetch = FetchType.EAGER)
  | 	private Set<Employee> employees;
  | 

not


  | 	@OneToMany(cascade = CascadeType.ALL,
  | 			   mappedBy = "employee",
  | 			   fetch = FetchType.EAGER)
  | 	private Set<Employee> employees; 
  | 

but anyway that wasn't problem.
This is what we did to fix the error we were getting ...

In the Company bean, changed employees to:


  | 	@OneToMany(cascade = {CascadeType.MERGE, CascadeType.REMOVE, CascadeType.REFRESH}, 
  | 			   mappedBy = "company",
  | 			   fetch = FetchType.EAGER)
  | 	private Set<Employee> employees;
  | 

So pretty much just removing the CascadeType.PERSIST (which is contained within CascadeType.ALL).

This works but don't understand why, if someone can explain that'd be awesome.

(To save myself here ... I did try this at some point but it musn't have worked before due to other code "fixes" I was trying out to fix this problem!)

There is one little problem to this solution though, if it is a problem to some at all.

If you have a new Company object containing a set of new Employees, those employees won't get persisted. You won't get an error message or warning message. It just doesn't get persisted.

Hmm ...

Hope this helps someone.
