Hi!

I want instantiate a entity in other diferent entity controller. For example, instantiate
Opportunity entity in Account controller. How can I do it? Thanks!

Use $this->getEntityManager(). There is a documentation

[krmn.msg]

I am using "$this->getEntityManager()->getRepository('Opportunity')->get('576c068c380779fb7')" and I'm sure that these object exists in database. But it gives a Error, that said it is null.
I was seen the documentation and I don't get the solution.

Sorry for the inconvenience
