[rules-users] RuleFlow Groups and retraction

[Markus Helbig]

Hi,

one question about using ruleflows:

1. i have a ruleflow consisting of 2 Nodes
2. i insert 2 facts
3. the 2 facts match the condition in rule for the second node, so
when inserting an activation is generated
4. but the rule in the first node will retract one of the 2 facts
5. it seems the activation for the second node is not cancelled also i
do a retract in the rule
6. now the activation in second node tries to execute and results in a
NullpointerException

What do i do wrong?

Cheers

Markus
