How to hold a Collection of Objects in memory for processing ?.
by vr
Hi All,
This is the rule defined in my drl file
rule "Entry"
salience 10
when
$alert : Alert()
$list : Alert ( sourceName=="DATA") from $alert.alerts // 1.
Iterate over List of ALerts
then
checkForAlertDescription($list); // 2. I am passing one Alert per
match
end
Is there a way to hold the *Entire List at Step one * in the Drools Memory
so that i can take the Entire list for processing with in the function
defined at Step 2
Instead of the single alert that i have at the moment
Any suggestions would be helpful.
Drools v 5.4.0 Final
-----
Thanks for the support ...!!!

Maintain assets synchronized between members of a team
by ciberg2
Hi,
My Drools project is going well and now it's time for some people starting
creating and deploying new Excel decision tables onto the repository.
For that we are using the Eclipse plugin, I've created a general project
that replicates the package structure so everyone can start deploying these
new tables.
My problem is maintaining all the projects in each team member computer
synchronized. Using Eclipse Tools I can commit and update existing assets
but I've not found a way to get all the new assets not existing in the local
computer.
The only way is getting resources from repository but that has to be done
one by one which is not an ideal way to do it because there will be many,
and to add to the problem doing that the downloaded excel files lose all
formatting and become corrupted.
I thought of using GIT to synch all the files but it seems silly to have to
put the files in a new repository when I already have them in one (Guvnor).
What do you think will be the best way to guarantee that all team members
have the same versions of the assests on their local computers?

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.
