Simple Process created with Modeller fails when deployed

florian_gau

Hi there,

after I created a first simple process (just a starting point, a user task and an end point) I wanted to deploy this process in Probe.

For the deployment I selected the saved bpmn20.xml file. Probe answers with "deployment successful".

When I switch to "Processes" I get the following exception (it seems, that the generated process is not generated properly):

Any ideas on that?

Thanks in advance.

How does your process-xml look like? Can you double-check that your process-definition has a name?

Hi,

I had exactly the same issue. Doing my first steps with Activiti I created a simple, small process with the Activiti Modeler which did result in a deployable but not listable (under Activiti Probe => Processes) .bmn20.xml file. I checked the xml and it does have a <process> tag with attributes 'id' and 'isExecutable'. No attribute named 'name'. When manually adding 'name="name"', listing works. But setting the 'name' attribute does not reflect back into the process model of the Modeler. When changing the model in the Modeler, saving and redeploying the same error occurs. I also haven't found an option to set a name (other then for the canvas) in the Modeler. But then, how do others work successfully with the Modeler and Probe?

This seems to be an error/a bug of the Modeler? Or am I doing something wrong?

Thanks for any hints,
Ruben

@ Ruben Which version of the modeler were you using? AFAIK, the name is added when you specify the name in the process properties

Hi,

I'm using the Activiti Modeler from Signavio which ships with the latest activiti (activiti-5.3.zip, VERSION file states 3.0.1). I haven't found process properties in the editor. All the example processes coming with the modeler lack a 'name' attribute in the .bpmn20.xml. Can't find a process name in the .signavio.xml either, only a canvas name. The sample processes are coming already deployed, too. The .bpmn20.xml files in the activiti-engine-examples differ significantly from the corresponding ones in activiti-modeler. Having set the 'name' attribute is the least.

So presumably my assumption to model a process with the Activiti Modeler and deploying it via Activiti Probe is not THE way, though delivering in one package does suggest it?

Hi,

I am using the version activiti 5.5 version,even I am getting same the error as below,if I create a process using activitii modeler,and deploy the xml using Activitii Probe,However,if I put the name attribute in the xml,It shows the process name in the list of the Processes Tab.Please let me know,if this got resolved.

So presumably my assumption to model a process with the Activiti Modeler and deploying it via Activiti Probe is not THE way, though delivering in one package does suggest it?

What exactly do you mean by this.Then please let me which is the best way to deploy the process,creating by the activitii modeler.Please provide a sample process if any.

Regards
Anita
