Start Process by Disabling Validation

Hi,I am parsing a bpmn file using Activiti and all goes well. However, if I do not define any 'script' in Script Task then bpmn file will not get deployed. I was going through the functions and came across "disableValidation" function. Now when I call this function and deploy the process, then proce

I was getting BpmnModel object using:
<code> BpmnModel model=repositoryService.getBpmnModel(String.valueOf(processInstance.getProcessDefinitionId())); </code>

But Process Instance object is not being initialized if Script Task Element does not contain any script.

Thanks for any help/pointer/suggestion.

I'm not really following .. having a script task element doesn't have any influence on this all.
Please post the process definition XML that is causing this.

Sorry for not being clear in the first place.

I have attached my bpmn xml file.

The same file get deployed perfectly fine if I just convert the script task to manual task. And after deployment I am able to get process instance from runtime service and then I retrieve bpmn model.

However, with script task, I get the error that no script found. I have also attached the log file. Thanks for the help.

My Process Definition (complete file also attached):

error:

</code>

In my case I just need to be able to populate bpmn model object using Activiti Parser. The scripts might and might not be present in the Script Task at the time when I need to parse bpmn file.
I also tried disable validation function at the time of deployment but even that did not work for me.

Thanks for the help.

I really appreciate any pointer in the right direction.
Please let me know if I can provide any further information.

So the exception is clear, you have no script element for the script task, which is invalid.

Disabling the validation should work … how did you try to disable it?

Yes, the exception is very clear and thus I disabled the validation while deploying the process (code below). But even after disabling the validation the process won't start executing. For example, even when I have disabled the validation, I cannot get bpmn model object from process instance as process could not be deployed.
<code>
DeploymentBuilder d = repositoryService.createDeployment();
   d.addClasspathResource("bpmnFiles/"+fileName);
   d.disableBpmnValidation();
   Deployment dep = d.deploy();

   runtimeService = processEngine.getRuntimeService();
   processInstance = runtimeService.startProcessInstanceByKey("myProcess");
</code>

Thanks,

Okay - and how does your BPMNParseHandler look like where you attach the script?
