Rights-Mamangement on Process-Definitions

[b_schnarr]

Hello at all,

lets say I model a new process in the Activiti modeler or in eclipse. Is it possible to define which user or which user groups can see and start this new process definition after the deployment?

Thanks and best regards
Ben

[frederikherema1]

This is possible by using the API. After deployment, you can add candidate starters for a certain process-definition (using repositoryService). Later on, when you want to display the possible processDefinitions, use the startableByUser(…) on ProcessDefinitionQuery to limit the visibility of definitions.

Please note that the engine does NOT enforce this constraint, its more of a convenience offered to apps building on top of activiti engine.

[b_schnarr]

Thanks for your reply. I assume that this is not valid for the activiti explorer? So all users can see and start all available processes in the explorer?

[frederikherema1]

Yes, activiti explorer doesn't take those values into account

[b_schnarr]

I saw that the repositoryService in REST API is only available in the legacy REST API. In the new REST API, you can use the GET-Method repository/process-definitions and parametrize the query with startableByUser, e.g.
http://host-ip/activiti-rest/service/repository/process-definitions?startableByUser=kermit.
Ok, understood. Is it possible to set these permissions in the activiti explorer, too? What must I change in the code that the explorer only shows processes the user is allowed to see?

Thanks for your answer and best regards
Ben

Hi,

The process definition list should be using a query that takes into account the startableByUser option as available on the ProcessDefinitionQuery.

Best regards,

[b_schnarr]

Could you give me a hint in which classes I can find those queries? That would be great.

Thanks and best regards
Ben

I checked out the whole project in eclipse and changed a few lines of code in the activiti-explorer module. Afterwoods, I created a new war file: right-click on the pom.xml of the activiti-webapp-explorer2, run-as –> maven build, goals: package. The generation of the war-file is successfull.

But when I deploy the app on tomcat, I get the following error:

<code>
HTTP Status 500 - org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'explorerApp' defined in ServletContext resource [/WEB-INF/activiti-ui-context.xml]: Cannot resolve reference to bean 'formPropertyRendererManager' while setting bean property 'formPropertyRendererManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'formPropertyRendererManager' defined in ServletContext resource [/WEB-INF/activiti-ui-context.xml]: Cannot create inner bean 'org.activiti.explorer.ui.form.DoubleFormPropertyRenderer#5de3dfa4' of type [org.activiti.explorer.ui.form.DoubleFormPropertyRenderer] while setting bean property 'propertyRenderers' with key [3]; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.activiti.explorer.ui.form.DoubleFormPropertyRenderer] for bean with name 'org.activiti.explorer.ui.form.DoubleFormPropertyRenderer#5de3dfa4' defined in ServletContext resource [/WEB-INF/activiti-ui-context.xml]; nested exception is java.lang.ClassNotFoundException: org.activiti.explorer.ui.form.DoubleFormPropertyRenderer
</code>

I only added one if-Statement in one class and nothing else. All other sources and dependancies are the same as in the Git-Repos. Did I miss something?

Thank you very much

The same result without any source code changes. I checked out the git project (master) in eclipse and builded the war of the activiti-webapp-explorer2 by right-klicking of the pom.xml–>Run as–>Maven build–>goals: package. When I try to open the login page, I get the mentioned error.

Thanks for your help and best regards

My operations in detail with eclipse Kepler:

1.) File –> Import –> Git –> Projects from Git –> Clone URI
2.) URI : https://github.com/Activiti/Activiti; Host: github.com, Respo Path: /Activiti/Activiti
3.) Branch Selection: master, clone submodules
4.) Import as general project

Now, the project is available in eclipse without any errors.

5.) Right click on the project –> Configure –> Convert to maven project

Now, the project is correctly recognized as a maven project without any errors.

6.) Right click on project –> Maven –> Update Project

7.) Right click on pom.xml of the main project –> Run As –> Maven build; Goal: package

You can see this:

After the deployment on tomcat, I open the following URL: http://post-ip:8080/activiti-webapp-explorer2-5.15-SNAPSHOT/ui/

Then, I get the following error:
