Here is an overview of the issue:

Key: EJB-2
Summary: [EntityBeans] generated ejbCreateImpl() method contains error
Type: Bug
Status: Closed
Priority: Major
Resolution: FIXED
Original Estimate: Unknown
Time Spent: Unknown
Remaining: Unknown
Project: EJB Cartridge
Assignee: Sascha-Matthias Kulawik
Reporter: Stefan Siegl

Environment: AndroMDA 3M2, Win2k
Description:
The ejb cartridge generates the <BeanName>Bean class for each entity of the model
(apart from other files ;)). Inside this class the method "ejbCreateImpl()" is
created. Inside this method the CMP fields will be set. The problem is that the method
tries to access the fields and does not use the accessor methods. This causes a
compile error, because the field is not present in this class but will be set in the
subclass generated by the EJB Container.
In my example I created a class called "HelloWorldData" with the stereotype
<<Entity>>. I added an attribute called "id" which is of the type "String" and added
the stereotype <<PrimaryKey>> to it. The additional attribute "text" (also a String)
is a normal field that should be persisted.
The transformations creates for this model the following code inside the
HelloWorldDataBean class:
protected void ejbCreateImpl() throws javax.ejb.CreateException{
if (id == null) {
id = new java.rmi.server.UID().toString();
}
}
