You are probably using the jBPM 5.1 Installer which ships with 5.2.0. The Guvnor workitem definition editor was added after that and is available in Guvnor 5.3.0.CR1. You can easily update guvnor in the jBPM installer:
1) In $jbpm-installer-dir$ edit build.properties, change

#   drools.guvnor.version=5.2.0.Final
#   drools.guvnor.url=https://repository.jboss.org/nexus/content/repositories/releases/org/drools/guvnor-distribution-wars/5.2.0.Final/guvnor-distribution-wars-5.2.0.Final-jboss-as-5.1.war
drools.guvnor.version=5.2.0.Final
drools.guvnor.url=https://repository.jboss.org/nexus/content/repositories/releases/org/drools/guvnor-distribution-wars/5.2.0.Final/guvnor-distribution-wars-5.2.0.Final-jboss-as-5.1.war

to

#   drools.guvnor.version=5.3.0.CR1
drools.guvnor.version=5.3.0.CR1
drools.guvnor.url=https://repository.jboss.org/nexus/content/repositories/releases/org/drools/guvnor-distribution-wars/5.3.0.CR1/guvnor-distribution-wars-5.3.0.CR1-jboss-as-5.1.war

2) While you are at it, also upgrade the web designer to the latest release, change

# the version of the Designer you want to use
# and the associated URL you want to get it from
designer.version=1.0.0.052-jboss
designer.url=http://sourceforge.net/projects/jbpm/files/designer/designer-1.0.0.052/

to

# the version of the Designer you want to use
# and the associated URL you want to get it from
designer.version=1.0.0.055-jboss
designer.url=http://sourceforge.net/projects/jbpm/files/designer/designer-1.0.0.055/

3) You also have to map your workitem to your implementation (this is not defined in the bpmn2), in $jbpm-installer-dir$/conf/META-INF/CustomWorkItemHandlers.conf see the examples of the pre-existing Log and Email workitems and add yours there as well

4) Run:
ant clean.demo
ant install.demo
ant start.demo
in $jbpm-installer-dir$

Note that by doing this you will loose your existing Guvnor repository, so you might want to save off any existing assets (via guvnor repository xml export for example) before running ant clean.demo

Hope this helps.

Hello,

I am trying to create a new Work Item Definition as shown in these videos:
http://vimeo.com/26126678

http://vimeo.com/29457538

But unfortely I can't find the option to create a new Work Item Definition.

After I defined the parameters and the Icon from the Work Item How can I define what the activity will do. For instance call a web-service, send a e-mail , etc...

I know that I have to implement a class, like explained in section 9.2.4 in the document below:

http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-flow/html_single/index.html#ch.Domain_Specific_Processes

It's the same when we are using the web-editor? Where I must deploy the class?

Att.
