I may be mistaken, but the stack trace looks as if a stateless
knowledge session is being run, wherein it executes a RHS
("employeePreloadSystemConstants") where some fact is being inserted.Not sure what *ought* to happen in this case, though: I've been trying to find this out ever since 5.1.x. A meagre "...do not support iterative insertions..." is all there is to be read, but what does this imply? Simply doesn't work in an unspecified way? May crash on workdays...?? A "tut, tut" from the Drools Team ??? ;-) -W On 18/02/2013, Mark Proctor <[email protected]> wrote: > Looks like an 'or' bug.
