FW: Issue with referencing a ManagedBean

[Faisal Mahmoud]

 


Below is my managed bean. In the constructor, I get a reference to the managed
property from Spring just to verify that it is available. I placed breakpoints
in the code at the getSiteList() method, and my breakpoint is never hit prior to
the error occuring.
