We are unable to delete a roadmap or picklist in the Clarity PPM New User Experience (UX) once the picklist is created and associated with the grid view. The error displayed when trying to delete the roadmap or picklist is Rdm.cannotDeletePicklists
Steps to Reproduce:
ERROR 2019-05-07 15:04:44,104 ppm.rest (clarity:user:......:PPM_REST_API) Error deleting picklist java.lang.ClassCastException: class java.math.BigDecimal cannot be cast to class java.lang.Long (java.math.BigDecimal and java.lang.Long are in module java.base of loader 'bootstrap')
This issue is no longer reproducible in 15.6.
