Configuration error[Cannot register class [models.User] in Ebean server]

[Ömer Faruk Gül]

Hi,

I'm experiencing a very strange problem. I'm using Play Framework and I have a model called User.

There are other methods in the model other than the setters and getters and they are causing a problem.

The line in the error that get my attention is this:

Caused by: java.lang.VerifyError: (class: models/User, method: doesLike signature: (Lmodels/Feed;)Ljava/lang/Boolean;) Incompatible object argument for function call

at java.lang.Class.forName0(Native Method) ~[na:1.6.0_43]

here is the whole error output:

play.api.Configuration$$anon$1: Configuration error[Cannot register class [models.User] in Ebean server]

What could be the problem?

[JAMES HARIG]

Do you have a default no argument constructor for the User class? If you don't, that might be the problem.

What does your models/User look like? (and specifically the doesLike method)

It should be a bug in either the EbeanORM enhancement or the Play enhancement.
