I get an error when building BPM example.

Hello!

When i deploy test BPM example, which i get from https://doc.cuba-platform.com/bpm-6.2/quick_start.html. I get error “ActivitiException: Errors while parsing:
[Validation set: ‘activiti-executable-process’ | Problem: ‘activiti-exclusive-gateway-condition-on-seq-flow’] : Default sequenceflow has a condition, which is not allowed - [Extra info : processDefinitionId = contractApproval | processDefinitionName = Contract approval | | id = sid-EBC8AD44-9BC5-4346-B8EE-8DBA7F4344A1 | ] ( line: 65, column: 120)”

Cuba version: 6.2.6
OS: Ubuntu 16

Has anyone encountered this problem?

Hi Alexey,
This kind of error appears if the default flows are specified incorrectly. Please, check the settings of your project.

Select the Not valid flow. Expand the Flow outcome dropdown list from the properties panel. It shows outcomes from the tasks before the gateway. Select the Not valid value.
The Valid flow should be marked as the default flow (if no other flows condition are true). Select the Valid flow and tick the Default flow property.

Select the Not approved flow node and select the Reject value in the Flow outcome list. Now if at least one of the managers performs the Reject action then this outcome will be initiated. Select the Approved flow node and check the Default flow checkbox.

https://doc.cuba-platform.com/bpm-6.2/qs_process_model_creation.html

I had the same problem and the issue wasn’t initially clear. So to make it very clear: The default flow cannot be connected to an outcome. So for the valid an approved flows, DO NOT specify an outcome. Simply mark them as default.

Sorry to pull this up this post from the dead.
