Hi Diptendu,
I don't think the 'target' attribute is meant to be used with
expressional values. [1]
I guess you might want to try with transition elements with cond
attribute, which is expressional [1], instead.
For example,
<transition target="Start" cond="user != null" />
<transition target="SomethingElse" cond="user == null" />
