Reformat it like this:
boolean vIsForm=true;
String vForwardName =
(aActionMapping.findForward(vWorkForwardName) == null)
? (vIsForm)
? "form"
: "task"
: vWorkForwardName;
or even like this:
boolean vIsForm=true;
String vForwardName =
(aActionMapping.findForward(vWorkForwardName) != null)
? vWorkForwardName
: (vIsForm)
? "form"
: "task"
Does it look simpler?
vIsForm does not seem to be changed in this snippet, so you can
simplify the above double ternary operation down to single ternary
operation:
String vForwardName =
(aActionMapping.findForward(vWorkForwardName) == null)
? "form"
: vWorkForwardName;
