[jboss-user] [JBoss Seam] - Re: Business process variables duplicted when updated.
Thank you Gavin for your PROMPT (yes in capitals :-) ) response.
I would like to verify if I am interpreting the right way what´s going on. Here is a
snippet from my code:
@Stateful
@Name("verifyData")
public class verificarDatosBean implements verificarDatos {
@In
@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
@EndTask
public String saveModifiedData() {
return "/home.seam";
}
@Remove @Destroy public void destroy(){}
public String getUnDato() {
return unDato;
}
public void setUnDato(String unDato) {
this.unDato = unDato;
}
}
1. When seam finds:
@In
private String unDato;
injects the the BUSSINESS_PROCESS variable unDato. (The variable was already created
elsewere with BUSSINESS_PROCESS scope AND I already called a method annotated with
@StartTask, so I am inside a BUSSINESS_PROCESS)
2. As soon as any method inside the object is executed (I think in my case it is the
getter because this EJB is acting as a Backing Bean) Seams finds:
private String unDato;
@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
and creates the new variable with the same name (unDato) and scope (unDato) but with
different Id.
3. When I execute:
@EndTask
public String saveModifiedData()
Seam sees that the task is completed and updates the original variable.
Forgive my verbosity but I want to be sure I am conceptually right. (So I learn once for
good)
