I'm using the newly-released (and very nice it is too!) v5.1-M3
installer (http://www.nuxeo.org/static/NuxeoEP/nuxeo-ep-5.1.0.M2-
installer.jar) now and trying to enable workflow for my new document
type.
Our new document type works in the UI, and I can successfully create
a new document with it. However, no matter what I try, I can't seem
to get the 'workflow' tab to appear on it in the Nuxeo workbench screen.
I've stumbled across the NXCore documentation (that I can see is
replicated in the nuxeo book here: http://doc.nuxeo.org/1.0-SNAPSHOT/
reference/html-single/nuxeo-book.html#nuxeo-core-reference).
This suggests that I define the life cycle I want the new document
type to follow by defining the
'org.nuxeo.ecm.core.lifecycle.LifeCycleService' extension point for
our data type. I've taken the 'lifecycle-contrib.xml' from the sample
project, and modified this for our data type.
Changing the type in this xml file from 'Sample' to my custom data
type 'Policy' and deploying into Jboss/Nuxeo now gives me this error
when I create a new document of our custom data type:
10:34:24,790 ERROR [STDERR] Jun 6, 2007 10:34:24 AM

SeamPhaseListener instances installed)
org.jboss.seam.contexts.PageContext.getPhaseId(PageContext.java:153)
The 'lifecycle-contrib.xml' file in the sample project we're using
looks like this:
<?xml version="1.0"?>
<component name="org.nuxeo.project.sample.lifecycle">
<extension target="org.nuxeo.ecm.core.lifecycle.LifeCycleService"
point="lifecycle">

</extension>
<extension target="org.nuxeo.ecm.core.lifecycle.LifeCycleService"
point="types">
<types>
<type name="Policy">policy</type>
</types>
</extension>
</component>
I have also tried simply using:
<?xml version="1.0"?>
<component name="org.nuxeo.project.sample.lifecycle">
<extension target="org.nuxeo.ecm.core.lifecycle.LifeCycleService"
point="types">
<types>
<type name="Policy">default</type>
</types>
</extension>
</component>
and defining the type 'Policy' to use the 'default' life cycle
definition, but this simply does nothing (not even the SEAM exception
above).
Where I'm going wrong? Should I be looking at 'nxworkflow-document-
rules-contrib.xml' as previously mentioned, or is this
'org.nuxeo.ecm.core.lifecycle.LifeCycleService' the right place to be
enabling workflow for this new data type?

Hi Craig,

We've created a new document type in Nuxeo and, with some
excellent help
from the people on this list, are now able to create new
documents in
this new document type.
Our next mission with Nuxeo is to try and workflow these
documents using
Nuxeo's excellent workflow facilities. We know they're excellent,
as we
can create a 'Note' document (one of the default types) and put that
through a workflow process.
How would we go about enabling workflow for the new document type
we've
just created?
Unfortunately, as far as we can see, we don't have much in the
way of
documentation to help us understand how to enable workflow on our
document type. The closest seems to be this:
http://public.dev.nuxeo.com/~ogrisel/nuxeo-book/workflow-
service.html
After some random looking through the code base, we have found a
'nxworkflow-document-rules-contrib.xml' in the
platform/nuxeo-platform-webapp-core project that seems to be
where the
'Note' document type's workflow is defined.
We've created a local copy of this in our sample project and
removed all
but one of the doc type declarations, substituting the last one
for our
document type. Needless to say this didn't work.
Did you think about referencing your new xml descriptor that contains
the workflow rules in the MANIFEST.MF of your bundle ?
As well, if you did a copy paste of an existing workflow rule did you
think about changing the component name (name="") in the xml
descriptor ?
Do not hesitate if you got more questions.
Cheers,
J.
Hi there. Yes, I had guessed I had to do these things. We've
created a 'nxworkflow-document-rules-contrib.xml' file in the OSGI-
INF folder in the sample project, and have added a reference to
this in the MANIFEST.MF:
nxworkflow-document-rules-contrib.xml:
<?xml version="1.0"?>
<component name="com.policymatter.workflow.nuxeo.workflowdocrules">
<documentation>
</documentation>
<require>org.nuxeo.ecm.platform.workflow.document.service.WorkflowRule
sService</require>
<extension
target="org.nuxeo.ecm.platform.workflow.document.service.WorkflowRules
Service" point="docTypeRule">
<documentation>

<i>PolicyMatter</i> document type.
<p/>

<docTypeRule docType="Policy">

workflowDefinition>
<workflowDefinition>document_review_serial</
workflowDefinition>
<workflowDefinition>document_review_approbation</
workflowDefinition>
</docTypeRule>
</extension>
</component>
MANIFEST.MF:
Manifest-Version: 1.0
Bundle-ManifestVersion: 1
Bundle-Name: Nuxeo Sample project
Bundle-SymbolicName: org.nuxeo.project.sample;singleton:=true
Bundle-Version: 1.0.0
Bundle-Vendor: Nuxeo
Provide-Package: org.nuxeo.project.sample
Require-Bundle: org.nuxeo.runtime,
org.nuxeo.ecm.core.api,
org.nuxeo.ecm.core,
org.nuxeo.ecm.webapp.core,
Nuxeo-Component: OSGI-INF/core-types-contrib.xml,
OSGI-INF/ecm-types-contrib.xml,
OSGI-INF/lifecycle-contrib.xml,
OSGI-INF/event-listener-contrib.xml,
OSGI-INF/directories-contrib.xml,
OSGI-INF/nxworkflow-document-rules-contrib.xml,
OSGI-INF/theme-contrib.xml
Doing this was just pure guesswork on my part, as I have no idea
what is required to enable workflow for this new document type.
Therefore, there are probably other areas of Nuxeo that need to be
told that we're now wanting to workflow this new document type.
However, I can't seem to find any documentation on what is required
to make this happen.
Interestingly, I do get this exception when I create a new document
with our new document type:
org.nuxeo.ecm.core.api.ClientException: Unable to get allowed state
transitions for document : 589f7a33-f6a1-4e2e-8aaa-536bcebb8d79
at
org.nuxeo.ecm.core.api.AbstractSession.getAllowedStateTransitions
(AbstractSession.java:1839)
...and:
10:29:44,201 INFO [LifeCycleServiceImpl] No life cycle associate
to document type : ComplexType: Policy; []
10:29:44,201 INFO [LifeCycleServiceImpl] No life cycle manager
found for document type = ComplexType: Policy; [] check out your
configuration.
...which suggests to me that there is somewhere else that I need to
define a 'life cycle manager' to handle this new document type.
Is this documented anywhere and, if not, can someone suggest a list
of config elements that I should look at and amend (over and above
the 'nxworkflow-document-rules-contrib.xml' file)?
Thanks for your help
