how to make a custom field read only when my issue transitions to the next workflow state

[Soumya Kinger]

I have a description field in my bug issue type. When I am in the "To Do" state of my workflow, I want this description field to be editable, but when my bug moves to "In Progress" state, this description field should become read only. Basically user should not be able to edit the description field once the issue migrates to "In Progress" state.

The linked post is about making the whole issue not editable not for a single field though

Good point, but it's still the right answer - you can't make a field non-editable by status.  The best you can do is move the edit into the workflow - take the field off the edit screen, then create transitions that go through a screen that includes it.
