The form view of a record that contains a workflow stage field may fail to load completely when the the following conditions are met:
1) Multiple parent workflow contexts attached (wf_context.parent field is empty)
2) At least one of those contexts has a stage_state that is empty
3) At least one of those contexts use the "Main flow" or "Simple Progress Bar" renderer
In that situation, a NullPointerException will be seen in the node log, and the form view will be incomplete and the page will not work correctly.
If the workflow stage field is removed from the form view, the form will work correctly.
Steps to Reproduce
For a permanent fix, review the Fixed In and Intended Fix Version fields to determine whether any versions have a planned or implemented fix.
On the context record that has the empty stage_state filed, set the stage_state to .
For requested items that no longer have context, hide the stage field from the form layout.
