[rules-users] Exception executing predicate

[Krishnan]

Hi all,

When exceptions occur during runtime of drools, is there a list of things to
see to understand what may be causing
this to happen ? I know it is a very generic question. I want to see if
there is a methodical way to understand what
to look for ?.

Any help is appreciated ?
