[rules-users] Rules updating error

[Ioannis Christodoulou]

Actually any change that builds another package will cause the kiescanner
to report errors on analysing the 'myFunctionCall(myGlobalList);'
expression.
e.g. change
System.out.println("List contains:"+list);  ===> System.out.println("Global
List Variable contains:"+list);

Ευχαριστώ πολύ,
   Ιωάννης Χριστοδούλου
