Re: [rules-users] Global variables not retaining changes.
Some extra information. The global is of type Integer. Now if I understand
correctly, using "+" on an Integer object is the same as "integer = new
Integer(integer.getValue() + 1)". It seems calling new on a global inside
the rule file causes the problem, because if I define my own integer wrapper
class with a simple set method and use this instead, the problem goes away.
Anyone have any suggestions???

Hi,
I currently have a drl file containing two globals, both objects. I
initialize these objects and populate the globals via
StatefulKnoweledgeSessions setGlobal("string", obj) method. During execution
some of the rules update values in these objects (I mostly using them for
keeping a count of the number of times a certain condition has been met). I
wish to periodically get the current value of the globals for use in other
parts of the program, but even though I know for a fact they have been
updated by some rule executions they are always the same value as when I
originally initialized them. Can anyone tell me why this is? And if its
possible to make them retain their value?
Cheers,
Justin
