Hi! Andy I can't change the type of a member from String to Long
becasue
it is an internal error of datanucleus in google apps, I I do not find
way of solving it.
All the exception is:
Problem accessing /Prode/JugarFecha.action. Reason:
java.lang.Long cannot be cast to java.lang.String
Caused by:
java.lang.ClassCastException: java.lang.Long cannot be cast to
java.lang.String
