Activiti Designer 5.9.0 released

trademak — Sun, 01 Apr 2012 13:13:46 GMT

Hi all,I've released a new Activiti Designer version (5.9.0).This is not just an upgrade with new features and bug fixes, we've also made a couple of changes to the core.First, we don't have separate .activiti and bpmn20.xml files anymore. We now have one .bpmn file that contains the BPMN 2.0 XML in

Hi, Activiti n00b here

I have just upgraded to 5.9.0 designer, great improvement particularly now that the boundary events move with the parents, thank you!

Quick question: I renamed my definition and am now deploying my workflows in my test case like this:

  repositoryService.createDeployment()
    .addClasspathResource("diagrams/TestWorkflow.bpmn").deploy();

However the process is failing to load - I can't spawn a new instance of my process, whereas I could before (when filename was .bpmn20.xml). The file is found - no exceptions thrown - it logs that it's processing it, but it fails to get into the engine. I am using the activiti-engine 5.9.0 artifact from Maven.

Is this related to BpmnDeployer where from line 71:

      if (resourceName.endsWith(BPMN_RESOURCE_SUFFIX)) {
        ResourceEntity resource = resources.get(resourceName);
        byte[] bytes = resource.getBytes();
…

For now I am making a chance to .bpmn and copying to .bpmn20.xml. Any advice appreciated and thanks again for a great product

Hi,

Thanks for the question, because I didn't make that clear in my post.
We changed the file extension to .bpmn as I noted and the Activiti Engine will be able to deploy files with that extension from version 5.10.
But with version 5.9 this is not yet the case, so the process definition is not parsed and therefore ignored.
If you generate a unit test from the .bpmn file (right-click on the .bpmn file then choose Activiti - generate unit test) you can see how you can implement this without needing to change the file extension.

RepositoryService repositoryService = activitiRule.getRepositoryService();
repositoryService.createDeployment().addInputStream("process.bpmn20.xml",
    new FileInputStream(filename)).deploy();

So you can add the process definition file (the .bpmn file) as an input stream and use a filename with the .bpmn20.xml extension.
Then the file is deployed as it should be and you don't have to change the .bpmn file.

Best regards,

Hi all,
For the next version we are looking at the implementation of the following features:

- Pools and lanes
- Text annotation
- Transaction and compensation support

But we welcome other requests for new features!

That's great thank you !
As you are talking about new feature, My top one would be "web services" (beeing able to produce a process from the designer that is close to the cxf provided sample). That means having pools, messages flows, mapping wsdl/xsd to operations and messages.

Cheers

Olivier

I have compared Manifest.MF for org.activiti.designer.model between version 5.8.1 and 5.9.0 and I've noticed that you're no longer exporting model package org.eclipse.bpmn20.
What is the reason for that?
I'm building extensions around Activiti Designer (custom property panels with filters based on selected node) and I'm referencing model classes in my code.

Re: Activiti Designer 5.9.0 released

trademak — Mon, 02 Apr 2012 13:47:06 GMT

Hi,

Right, the model has changed to a simple Java POJO model.
The semantics should however be the same as the previous model.
So the CustomServiceTask functionality still works with CustomProperty objects.
You can find all available model objects in the org.activiti.designer.bpmn2.model package.
Let me know if you run into issues with your custom developed functionality.

Best regards,

Thanks Tijs I will make the changes today.

Hi,

we are generating BPMN process-XML from another application, but without diagram information.
In Activiti 5.8, the designer reverse-engineered an appropriate diagram from the XML.
In Activiti 5.9, this doesn't work anymore.

Was this feature removed intentionally and is there a workaround?

Best Regards,
Florian

Re: Activiti Designer 5.9.0 released

trademak — Tue, 03 Apr 2012 11:22:45 GMT

Hi Florian,

Good point. That's currently left out of the release, but it would certainly be possible to bring it back again.
It depends a bit on the user demand for this, because there's quite a bit of logic needed for this.
So if more users are in need of this I can certainly take a look at it.

Best regards,

I appreciate the release of Activiti Designer 5.9 and I especially hope that any performance problems I was facing with the previous version will be gone. Thank you for your work on it.

Are there any plans to make the designer available on Eclipse Marketplace?

Regarding the future development: I am especially looking forward to the support for pools and lanes since they are an essential part of BPMN 2.0.

What about deploymentResources via Spring?
I changed the extension in my activiti-context file but I am getting this error:

java.lang.NullPointerException
 at org.activiti.engine.impl.cmd.DeployCmd.deploymentsDiffer(DeployCmd.java:72)

which correspond to this …if(!savedResource.isGenerated())…any idea?

Can you create a test case that reproduces this error, then I can take a look at it.

Hi everyone,

I have been using Activity Designer 5.9.0 for a couple of days and I find it a great supporting tool.

Is it still possible to directly import BPMN 2.0 diagrams from Signavio Modeler, as in the previous version of the designer?

Best regards,
Alberto

Hi,

Thanks,

It's not very easy to provide a test with all the spring configuration.

basically what I am using in my activiti-context.xml is this

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
  <property name="history" value="full" />
 <property name="dataSource" ref="dataSource" />
 <property name="transactionManager" ref="transactionManager" />
 <property name="databaseSchemaUpdate" value="true" />
 <property name="mailServerHost" value="${app.pmsmail.server}" />
 <property name="mailServerPort" value="25" />
 <property name="jpaEntityManagerFactory" ref="entityManagerFactory" />
 <property name="jpaHandleTransaction" value="true" />
 <property name="jpaCloseEntityManager" value="true" />
 <property name="jobExecutorActivate" value="false" />
 <property name="deploymentResources">
  <list>
   <value>/diagrams/projectRoutingProcess/ProjectRoutingProcess.bpmn20.xml</value>
  </list>
 </property>

I renamed the file in my project, so I can use the new designer, and I changed the path accordingly <value>/diagrams/projectRoutingProcess/ProjectRoutingProcess.bpmn</value>that's when I got the exception

Hi,

changed my existing diagrams from .bpmn20.xml to bpmn.xml as well.
Unfortunately, automatic deployment of diagrams fails to process the given resources.
As I digged into org.activiti.engine.impl.bpmn.deployer.BpmnDeployer.deploy(…) the resources still are
checked against bpmn20.xml-suffix. So the default Deployer will skip the given resources unless suffixed with the previous ending.

Can you confirm this ?

What are my short-term options ?

a) Keep the "bpmn20.xml" ending and open and design them in Eclipse with 5.9 via the "Open With…" dialog instead a comfortable "double-click" - which by the way works.

b) Write my own Deployer ?

trademak — Thu, 05 Apr 2012 07:36:26 GMT

Hi,

In the current trunk of Activiti this is already implemented. So you don't have to write your own deployer.
Another solution could be to keep using .bpmn20.xml as the model file extension and use open with.

Hi
As Florian I think reverse-engineering from XML would be very helpful.
When do you think version with lanes and pools will be available ?
Thank

Hi,

Have you planned the support of the event based gateway in the next version of the designer ?

I am currently trying to evaluate this feature and the only way I have found to do it is to use the activiti-modeler (from signavio), but it does not seem to be really supported anymore (I had to patch the bpmn20.xml file manually to be able to load it in activiti-explorer).

Thanks& Regards,
Vincent

I tried activiti-designer-integration 5.9 but it's not found.

Is there a method to use Activiti Designer 5.8?
The installation site http://activiti.org/designer/update/ always go to version 5.9, and can not get 5.8.

Thanks.
