When designing the workflow I choose the candidateGroups fixed value options, as shown in the screenshots.
These groups are created in the Identigroup , ogranizatin tab.

When trying to start the process instance , keep geting the below number format error for the group,
I have worked on multiple workflows with the community edition with activiti:candidateGroups takes the groupname string, and resolves correctly.
Not clearly sure whats different in the APS .
Any advice would be helpful, thanks in advance.
