Re: [rules-users] how to retract all documents created in the following scenario
Here I was too hasty taking the Document pattern as granted. The
createError only fires if field1 *and* field2 are null/"", but the
initial statement says "...if *any* field is null...".
Therefore, you must use
when
not Error()
( Document( field1== null || == ("") )
or
Document( field2 == null || == ("") ) )
then

Error fact0 = new Error();

insert(fact0);

rule "retractBadDocs"
when
Error()
$doc: Document()

retract( $doc );
