Hi,


I have the following drl file.


==================================

package bugTestingFail

rule "Price hits Target"
when
eval ( true )
then
end

==================================


It is managed by a RuleAgent.


However, when I change the drl file from the source, I get the following except
ion:


RuleAgent(MARKET_DATA) INFO (Wed Aug 06 15:43:53 EST 2008): Applying changes to
the rulebase.

This only happens to me when I am editing rules files that have an eval
condition.
