Subject: Re: [drools-user] Data Sharing in rules
Thanks for ur reply Mark but I am not getting the expected result. I have
attached a demo rule file to test application data.
Please have a look at the attached demo rule file where I have used
application data. I changed the value of count(global variable) to Integer(0)
in Rule 1 and I am getting null in Rule 2.
here is the outcome when the rules are fired.
0
null
Please see where am I making mistake.
With Regards
Amit
