When starting a Workflow, required fields that are based on field dependencies do not display in the Workflow Start Dialog if they are blank.
Required fields based on field dependencies do not display in Workflow Start Dialog if blank.
To resolve this issue, add the document fields that are required based on field dependencies to the Entry Criteria of a lifecycle state. Then, add that state to the workflow Start step, under Next State Entry Criteria. Doing this, allows the fields to display in the Workflow Start Dialog.
