Hi All,
we have a scenario whereby, several documents are created as part of the
ruleflow. at the end of the ruleflow, if any of the fields in the document
is empty or null, we would like to create a error (only one error) and
retract all the documents so far.
rule "createError"
ruleflow-group "mrHardErrors"
no-loop true
dialect "mvel"
when
emptyDoc : Document( field1== null || == ( "" ) , field2 == null || == (
""
) )
doc : Document( )
then
Error fact0 = new Error();
fact0.setErrorCode( "code1" );
insert(fact0 );
retract( emptyDoc);
end
I see that error is created more than once ( as many as matching documents )
How do we ensure that all documents are retracted and also the error is
created only once ?

You could do something like this:
rule 'empty documents'
...
when
$emptyDocs: List(size>0) from collect ( Document( field1== null || == (
"" ) , field2 == null || == ( "") ) )
then
//insert an error
Error fact0 = new Error();
fact0.setErrorCode( "code1" );
insert(fact0 );
//retract empty documents
for (int i=0; i < $emptyDocs.size(); i++){
retract( $emptyDocs.get(i));
}
end

am I making a mistake somewhere ?

Did you try using Java dialect instead of MVEL?

The rule shown below isn't correct. It will create an Error, but it
won't retract *all* Document facts as there may be some that do not
have field1 or field2 set to null/"".

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
