Fusion: Null pointer exception when using sliding windows
by burmanator
I am getting a null pointer exception when I try and use a sliding window.
The rule I'm trying to run is:
$primary : Foo($name : Name) over window length(24)
$prev : ArrayList(size<1) from collect ( Foo(Name == $name, this before
$primary))
I am trying to look at the last 24 Foo events and have the rule only trigger
when an event with that name hasn't been seen before. I also get a null
pointer when I try and do a time window and no Foo events happen within the
window. Shouldn't the rule just not fire?

Designer for Guvnor 5.3.5
by Lance Leverich
Can anyone point me to where I can find the jBPM designer tool for use
within Guvnor v5.3.5? Instead of getting a download option, all we get is
the error message telling us that Guvnor couldn't find the designer tool.

Create package in Guvnor via REST API fail (Missing package name)
by Magic
Hi,
I am trying to operate my local 5.5.0 Guvnor through RESTful API and have
some trouble.
For example, below is my code to create a package through a InputStream DRL.
The DRL string is copied from
org.drools.guvnor.server.util.FileManagerUtilsTest.java
=====================================================================
String content = "package testClassicDRLImport\n import blah \n rule 'ola'
\n when \n then \n end \n rule 'hola' \n when \n then \n end";
HttpClient client = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(baseURL + "/rest/packages");
httpPost.addHeader("Authorization", securityToken);
httpPost.addHeader("Accept", MediaType.APPLICATION_JSON);
httpPost.addHeader("Content-Type", MediaType.APPLICATION_OCTET_STREAM);
InputStreamEntity entity = new
InputStreamEntity(IOUtils.toInputStream(comment), comment.length(),
ContentType.APPLICATION_OCTET_STREAM);
httpPost.setEntity(entity);
HttpResponse response = client.execute(httpPost);
=====================================================================
But, I still got an error that told me "Missing package name":
Caused by: java.lang.IllegalArgumentException: Missing package name.

I really don't know what's wrong and any help is really appreciate!

NullPointerException when using bean property which happens to be a Enum name
by Sean Su
I am using 5.5.0.Final and I think I may have run into a bug.
Assuming I have a class Foo that has a getter which is getMyEnum().
Also I have a Enum class which happens to have the name MyEnum.
When writing rules, I have
$foo : Foo (MyEnum == MyEnum.someItem)
This line will throw NullPointerException.
I have to write it as:
$foo : Foo (getMyEnum() == MyEnum.someItem)
This statement will work just fine.
The workaround is ok for DRL. However I tested this on Guvnor and the rule
editor would generate the DRL just like the first statement (MyEnum ==
MyEnum.someItem). So we would be out of luck there.
Has anyone ever ran into this before.
Thanks
Sean

drools queries: strange dependency
by upalik
This message was cross-posted to stack-exchange. If someone wants to answer
there, the URL is
http://stackoverflow.com/questions/15922343/drools-queries-strange-depend...
.
I'm somewhat new to Drools, and experienced this strange behavior during
writing a query.
To start with, the Hotel class here is a subclass of PlaceImpl, which
implements the interface Place. PlaceImpl itself is a subclass (via another
class) of OntologyClassImpl, where the method getClasses() is implemented in
the most trivial way: it returns an already existing java.util.Set of
objects. In short, getClasses() is accessible from both Place interface and
Hotel class.
My problem is this: The following query does not return any result even when
there are matching Hotels.
query "qryRomantic" $e: Hotel (classes contains
Semantics.AMB_Romantic)end
However, if I replace Hotel with Place, then the /query returns desired
results/, although the ONLY condition-setting rules are written for Hotel,
as follows. (This rule actually gets fired several times.)
rule "Set semantic class Romantic"no-loop when $hotel: Hotel( ...
conditions go here ... ) then modify ($hotel){
addToClasses(Semantics.AMB_Romantic) }end
It does not end there.
if I add another query to the rule file, for exactly the opposite condition
as follows,
query "qryNonRomantic" $e: Hotel (classes not contains
Semantics.AMB_Romantic)end
then the /first query/ starts to return the desired results, /EVEN WHEN the
new query is not called at all/!
What am I doing wrong? I'd be really grateful for any pointers.
