Presumably selectedScript is a property of OrmedContext, and changing
its value here fires a propertyChangeEvent, which re-activates this
rule when the OrmedContext fact's slots change (even though you're not
matching on the selectedScript property, the rule is still
reactivated.)
You really only mean this rule to apply when selectedScript is nil, so
you should state that explicitly:
(defrule ASP1
(OrmedContext
(readyToRun TRUE)
(task "script")
(selectedScript nil)
(OBJECT ?c)
)
...
When the rule fires, selectedScript becomes non-nil, and the rule
won't be reactivated.
