Package snapshots in Guvnor have wrong list of rules
by sappelhans
Using Guvnor 5.1.1, I build a package using a custom selector that filters on
a rules' status; then take a snapshot. In the Package Snapshot tab
selecting "Business rule assets" from the navigation tree shows all the
rules from the package, not the filtered subset. But I know the selector
worked because the binary version of the snapshot downloaded via the
Deployment URL includes only the filtered subset.
Why are the assets viewable in the tree not in sync with those in the
deployed binary?

Expiry of events not occurring for sliding window
by cfuser
I'll preface this by saying this may not be the correct way to do this, so
suggestions welcome...
For this example, the name can be something like 'collector1', 'collector2'.
For each collector, there are normalized stats, like 'CPU', 'IO', etc.
<pre>
// Imports and other stuff
declare InstanceHealth
@role(event)
@expires(10s)
@timestamp(timeStamp)
end
rule "Iostats above 90 over 5 seconds"
when
$mih:InstanceHealth($id:id, $luid:name, $stat:stat )
from entry-point "stat-stream"
$measure : Number( doubleValue > 90 )
from accumulate(
InstanceHealth( $inst:name==$luid, $value:value,
stat==$stat)
over window:time( 5s ) from entry-point "stat-stream",
average($value))
then
logger.warn( "--------Average--------------" );
logger.warn( $mih.hashCode() + " // "+$stat +" // "+$id+" :
"+$luid +" == "+$measure );
// doStuff based upon the name and stat
end
rule "Log instance"
when
$m:InstanceHealth($id:id, $stat:stat, $inst:name, $v:value )
from entry-point "stat-stream"
then
logger.warn( "------------Instance--------------" );
logger.warn( "--"+$inst+" == "+$stat +" value = "+$v );
end
</pre>
So the 'Iostats above 90 over 5 seconds' rule is trying to match up stats
with collectors so there are no cross-products (stats aren't accumulated
across collectors and each stat type gets it's own evaluation). This
actually seems to be working, except the InstanceHealth objects don't seem
to be being evicted and I'm apparently getting multiple activations (?).
Note when I remove the line w/ the $mih binding, things get evicted fine but
I don't have access to the name, stat, etc. TIA.
A snippet of a log (I can confirm that three different iostats were inserted
for collector2)

Regression with Drools 5.3.0-CR1
by Swindells, Thomas
I've just tried upgrading from Drools 5.3.0-CR1 from the beta and I've hit a regression.
JBoss seems to have been down for most of today so I haven't been able to raise a Jira for it.
In our model we have Facts which contain fields of java.lang.class, we then have a rule which checks that they aren't null.
Eg
Fact { Class<Object> classField}
Rule "xyz"
When
Fact(classField != null)
Then
...
End
This is giving the following exception
Caused by: java.lang.ClassCastException: org.drools.base.field.ObjectFieldImpl cannot be cast to org.drools.base.field.ClassFieldImpl

Wrapping the classField != null within an eval appears to be a work around.
This is in the suspect method:
public boolean evaluate(InternalWorkingMemory workingMemory,
final InternalReadAccessor extractor,
final Object object1, final FieldValue object2) {
Object value1 = extractor.getValue( workingMemory, object1 );
Object value2 = object2.getValue();
if ( value2 == null ) {
ClassFieldImpl classField = (ClassFieldImpl) object2;
value2 = classField.resolve( workingMemory );
}
return comparator.equals( value1, value2 );
}
I think the if statement just needs an instanceof check as well or some other way to track the fact that null may be a valid value to be comparing with!

Not able to call parameterizied Java method in LHS
by Tinku
I tried to invoke parameterizied call to the java method and tried to compare
the return parameter from the method in the 'eval' function..The rule is not
getting executed ..
I am not sure if it is unable to invoke the java method and fetch the return
parameter or there is an issue with rule syntax..
Please help me in this regard.
LHS of the rule :
**************************************
import com.customObject
rule A
when
$B : customObject()
eval($B.getValue("Database").equals("ORACLE"))
then
System.out.println("The database object is oracle")
end

Re: [rules-users] [rules-dev] java.lang.NullPointerException while testing
by Esteban Aliverti
First of all, I' moving this to drools-users list.
The problem seems to be that the application is not finding the change-set
file. Where is the ChangeSet(12).xml file placed? Is it reachable at the
first level of the classpath? Try to debug and see if the resource is in the
classpath. Try with this first:
this.getClass().getClassLoader().getResource("ChangeSet(12).xml");
Another solution could be to use a URLResource pointing to package's
change-set in Guvnor.
Best Regards,
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Can you remove logging information from BatchExecutionCommand?
by dunnlow
I am sending a batchexecution command to a drools server:
8<...
MyBean mb = new MyBean();
List<Command> cmds = new ArrayList<Command>();
InsertObjectCommand insertCmd = (InsertObjectCommand)
CommandFactory.newInsert(mb);
insertCmd.setOutIdentifier("inserter");
insertCmd.setEntryPoint("Default");
cmds.add(insertCmd);
FireAllRulesCommand fireAllRulesCommand = new FireAllRulesCommand();
cmds.add(fireAllRulesCommand);
BatchExecutionCommand command =
CommandFactory.newBatchExecution(cmds,"ksession1");
String xml BatchExecutionHelper.newXstreammarshaller().toXML(command);
8<...
The xml created by that last line contains A LOT of logging information and
includes characters that seem to be invalid. (drools server throws a
"ConvertsionException, Invalid character reference: null character not
allowed in XML content" when it reads the XML)
Is there a way to tell the BatchExecutionHelper NOT not to include that
logger information?
ps. I tried things like turning off the root logger programmatically before
calling. Also, I tried setting a global parameter "logger" to a null object
(I saw that somewhere) but that didn't work either.
commands.add(CommandFactory.newSetGlobal("logger", null));
Thanks for any insight.

Date validation in Guvnor
by mick00
Hi,
I want to validate the date format in my rule. I just want to check whether
my date is in the given format(yyyy-mm-dd) in my rule in Guvnor. Is it
possible to do such validation in Guvnor? I tried the same but got an
exception stating that the date is not in the given format(dd-MMM-yyyy). Can
someone suggest a solution as to how to validate the date in Guvnor?
Thanks,
mick
