Unexpected exception: Invalid value for enum form property..

[sergiofigueras_]

Hi everyone!

I'm trying to integrate Activiti BPM (5.10) with our system. So, to do that, I'm rendering the form properties on our client (Primefaces). But, when I've an enum form type property and try to submit that, I don't know what I'm missing, and I've got this error:

4:25:42,030 SEVERE [org.activiti.engine.impl.interceptor.CommandContext] Error while closing command context: org.activiti.engine.ActivitiException: Invalid value for enum form property: Negar
   at org.activiti.engine.impl.form.EnumFormType.validateValue(EnumFormType.java:64) [:5.10]

   at org.activiti.engine.impl.FormServiceImpl.submitTaskFormData(FormServiceImpl.java:68) [:5.10]

I'm setting the process variables like this:

    public void submitTaskFormData(String taskId, Map<String, String> values) {
        ProcessEngine pe = ProcessEngines.getDefaultProcessEngine();
        pe.getFormService().submitTaskFormData(taskId, values);
    }‍‍‍‍

And that's my process file:

Don't see anything wrong there. Could you strip your process, and create a simple unit test which shows the problem?

See http://forums.activiti.org/en/viewtopic.php?f=6&t=4645 on how to create such unit test

Hi jbarrez,

I appreciate your attention. Thank you.

That was my mistake, I was switching my map values (where I should place the key, i was placing the value). Sorry and thank you!
