Hi everyone i tried CDI with Activiti but i keep getting this error :
Unknown property used in expression: #{bookOrder.validates()}Caused by: org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'bookOrder'
Unknown property used in expression: #{bookOrder.validates()}
Caused by: org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'bookOrder'
My BookOrder class :
@Named("bookOrder")public class BookOrder { private static final long serialVersionUID = 1L; private String isbn; private boolean approved; public String getIsbn() { return isbn; } public void setIsbn(String isbn) { this.isbn = isbn; } public boolean isApproved() { return approved; } public void setApproved(boolean approved) { this.approved = approved; } public void validates() { System.out.println("Testing the CDI ..."); }}
@Named("bookOrder")public class BookOrder { private static final long serialVersionUID = 1L; private String isbn; private boolean approved; public String getIsbn() { return isbn; } public void setIsbn(String isbn) { this.isbn = isbn; } public boolean isApproved() { return approved; } public void setApproved(boolean approved) { this.approved = approved; } public void validates() { System.out.println("Testing the CDI ..."); }
}
and the BPMN file :

Any ideas what i'm doing Wrong here ??
What platform are you running on?
I solved the problem i'm using spring with JSF i declared the beans in my activiti.cfg.xml , the problem i'm facing is that inside the validate method i have bookOrder.getIsbn when i call it it retrieves the value i want but when processing it vial ServiceTask it always retrievs NullPointerException
