Extension Elements in Lanes

[jakub_telicki]

Hi,

Following the User Guide (http://activiti.org/userguide/index.html#bpmnCustomExtensions) I would like to add properties to Lanes used in process definition.

I have created "extensionElements" element in Lane definition and added "activiti:field" element inside. Definition is parsed correctly and the process can be deployed on the Activiti engine.
However during parsing (by custom parser usage) or after process is deployed (through RepositoryService), I am not able to access data defined in the extensionElement.

Is the extensionElement supported for Lanes ?
Maybe I'm doing something wrong and someone could give some hints, thanks.

Failing test case:
[java]
    @Test
    @Deployment   
    public void testLaneExtensionElement() {
        ProcessDefinition processDefinition = rule.getRepositoryService().createProcessDefinitionQuery()
                .processDefinitionKey("swimlane-extension").singleResult();
        BpmnModel model = rule.getRepositoryService().getBpmnModel(processDefinition.getId());
        Process bpmnProcess = model.getMainProcess();
        for (Lane l : bpmnProcess.getLanes()) {
            Map<String, List<ExtensionElement>> extensions = l.getExtensionElements();
            Assert.assertTrue(extensions.size() > 0);
        }
    }
[/java]

Correct, it's not parsed and exported currently. However this would be easy to add, so please create a JIRA issue and I'll look into it.

Thanks,
