I'm having problem with class "within" a class.
1) Main initialize class "firstclass", passing callbackmodule ("main") and event ("from1st")
2) Main has a sub from1st
3) class "firstclass" initialize another class ("secondcalss"), passing callbackmodule("firstclass") and event ("from2nd")
4) firstclass has sub from2nd, it does something and then calls its own callback/event (main/from1st)
5) class "secondclass" defines a button witch a click event
6) the click event does something and then calls its own callback/event (firstclass/from2nd)
The click event cause an error.
A) when class inits are called with Me the error is:
java.lang.ClassNotFoundException: boten.cls1.[event=from1st, main=null, parent=class boten.cls1.main[/b]
B) when class inits are called with explicit names ("Main" & "firstclass") the error is:
java.lang.NoSuchFieldException: processBA
How can I do this. Attached is an sample project.
logs are here:
log for case A
log for case B
