Problem using 'selected' attribute of dropDown component
Valid Assumptions:
1. Developer is not a novice
2. Problem has been verified by third party
3. Using Netbean 5.5 plus Visual Web Pack 5.5
Problem:
The 'selected' attribute of the webuijsf:dropDown throws 'Component Error'
<webuijsf:dropDown... selected="#{address$CreateUI.addressFormBean.accessLevel}" />
where:
a. 'selected' is the object that represents the selection made from the available options
b. 'accessLevel' is java.lang.String with get/setter methods
ERROR:
javax.el.ELException: javax.faces.el.PropertyNotFoundException: javax.el.PropertyNotFoundException: Target Unreachable,'addressFormBean' returnednull
