Activiti 5.8 Error while getting form properties

[partizano]

Hi Activiti Team!

I have moved to version 5.8 (from 5.6). In my process instance user task has one form property. I try to get it using rest api (http://localhost:8080/activiti-rest/service/form/732/properties) and got the error:

I try to get the same form property using Activiti API and it works. Is it the bug or I am doing something wrong?

Thanks

Hi,

That's a bug. I'll make sure it's fixed in trunk. For now you can work around the bug by defining a type attribute in the form property.

Best regards,
