Thank you.
Is it discouraged or is it considered a bad practice to use static code in
OGNL? It is disallowed by default.
Actually, the code would be something like:
<s:if test="%{@com.company.project.package.Util@isUserInSession()}">
Do you think it is a better practice to use a base class whenever possible?
<s:if test="%{userInSession()}"> looks simpler.
