Protobuf error

Hi,
Drools Workbench has started to get failing tests due to this:-

Has something changed upstream? Do we need additional dependencies?
I remember seeing on IRC yesterday that marshalling had broken(?) is this
related.

Beta3 sanity check
by Michael Anstis
Hello,
I've tested Beta3 kie-drools-wb and kie-wb on AS7. These are my findings:-
*kie-drools-wb
*1) Generally looked OK to me
2) The JGIT daemon is not terminated when the webapp is removed/disabled
(I've emailed Alexandre).
*kie-wb
*
1) dom4j.jar needs deleting from WEB-INF/lib
2) I did not test any jBPM related screens (Task List, Designer etc)
3) The JGIT daemon is not terminated when the webapp is removed/disabled
(I've emailed Alexandre).
4 I encountered the following error:-
09:46:19,545 ERROR [stderr] (http--127.0.0.1-8080-2)
java.lang.NullPointerException

org.jbpm.console.ng.bd.backend.server.DeploymentManagerEntryPointImpl$Proxy$_$$_WeldClientProxy.autoDeploy(DeploymentManagerEntryPointImpl$Proxy$_$$_WeldClientProxy.java)
This came about by creating a "New Project" and "Build & Deploying" it. The
project did not contain any jBMP assets (only a dependency on a JAR
uploaded to Guvnor's M2 Repository and a simple rule).
It didn't throw any errors to the UI so I don't think it's serious.
Otherwise both were OK.
I've asked Toni and Jervis to perform a sanity check too.
With kind regards,
Mike

New rules are not reflecting at runtime without Binary package build in Guvnor UI
by Antin Brucelee -X (abrucele - INFOSYS TECHNOLOGIES LIMITED＠Cisco)
Hi,
I have a requirement of executing all the rules under a specific package. The new rules getting added in Guvnor API and Standalone editior are not getting reflected until I build the Binary package again using Guvnor UI. I want to allow users to create new rules and want them to be active immediately without coming to Guvnor to build the binary again.
I tried making a GET request to "http://... /rest/packages/SupplyChain/binary" to build the binary again, but the new rule is not reflected. I also tried the following configuration also.
ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "2");
ResourceFactory.getResourceChangeScannerService().configure(sconf);
KnowledgeAgentConfiguration kaconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
kaconf.setProperty( "drools.agent.scanDirectories","true" );
kaconf.setProperty("drools.agent.scanResources", "true");
kaconf.setProperty("drools.agent.newInstance", "false");
Please let me know if there is any other way of building the package with all the latest updates (including new assets) using REST API ?
Thanks
Bruce

Guvnor Standalone editor - How to copy an existing asset (Decision table)
by Antin Brucelee -X (abrucele - INFOSYS TECHNOLOGIES LIMITED＠Cisco)
Hi,
I am using Guvnor Standalone editor in my website to display and allow editing the rules. I have a requirement to copy existing rules and then allow users to make any changes on top of it.
I see the 'copy' feature is available Guvnor UI. Is there a way to achieve this feature by using REST API and Standalone editor in my website ?
Thanks
