Hello,
Doesn't really anyone have any logical explanation of why such a rule loops?
To remind the rule:
rule "Hello World"
no-loop
when
$fact1 : MyFactBean1( )
$fact2 : MyFactBean2( ) from $fact1
then
System.out.println("Fired!!!");
update($fact1);
end
If I don't use 'from' everything is fine.
I really didn't find in a documentation, that 'from' causes any special behaviour of the rule looping.
Best regards,

Thanks for answer, Vikrant, but I don't think so. I have always used no-loop without any additions and it worked (when I didn't use from). BTW, if you comment a condition with from, then the rule does not loop. I also checked with "no-loop true" and result is the same.
Best regards,

I have to quickly recheck the documentation by I think you have to write "no-loop true". Just writing no-loop defaults to false I guess.

Hello,
why does such a rule always loop? Even if no-loop is used?
rule "Hello World"
no-loop
when
$fact1 : MyFactBean1( )
$fact2 : MyFactBean2( ) from $fact1
then
System.out.println("Fired!!!");
update($fact1);
end
The full code of my test application and drl is attached.
