I am new in ADF JSF please assist, I am trying to map my Managed bean scope like request ,pageFlow and backingBean . but getting following errors,
ManagedBean -- Scope = request Error -- javax.el.PropertyNotFoundException: Target Unreachable, 'ManagedBean' returned null ManagedBean --- scope = backingBean or pageFlow Error --- An invalid object operation was invoked on type View Object with name EmployeeViewImpl_0
This is the exception:
javax.el.ELException: oracle.jbo.InvalidObjAccessException: JBO-25036: An invalid object operation was invoked on type View Object with name EmployeeViewImpl_0 at javax.el.BeanELResolver.getValue(BeanELResolver.java:266) at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:143) at com.sun.faces.el.FacesCompositeELResolver.getValue(FacesCompositeELResolver.java:72) at com.sun.el.parser.AstValue.getValue(AstValue.java:118)
I have had the same issue and I have solved. My stack trace was similar and my problem was that I was invoking an action method of a Managed Bean from a task flow, but in the managed bean, this method had as return: void. And this was my mistake.
I change the type of return to String and all works fine.
I hope this help you. Marcos.
