Hello. I keep trying to use the EventContext and made some advances.
As Joshua said the enums can be sent between the onPassivate and
onActivate methods (Thank you Joshua :).
But the problem is that I keep finding very strange problems. I
have isolated the piece of code that is giving me hell. I'm passing
two enums to the onActivate and I do inside two nested switch, but it
always fails when trying to read the value of the second enum at the
second switch and gives the classic:
java.lang.VerifyError Illegal constant pool index
And the stacktrace leads to the line where I first set an attribute
to the destiny page.
If I comment the second switch, the code works, but I need to work
with the value of the enum (that's why I'm passing it).
As I don't know if I'm allowed to send attached files, I copy the
abbreviated code down here. Sorry if it bothers. The code problem is
at the deep bottom. Getters and setters are omitted. Thanks on
advance.
