Generate defaults for blank UI fields. A present parameter with an empty value bypasses the new checks. The output loop then writes that empty value, so the blank-field case remains unfixed.

  • moveit_setup_assistant/moveit_setup_controllers/src/moveit_controllers_config.cpp#L193-L199: treat absent and empty values as needing defaults, without emitting duplicate keys.
  • moveit_setup_assistant/moveit_setup_controllers/test/test_controllers.cpp#L205-L206: expect follow_joint_trajectory and true for empty inputs.

Update the controller parameter emission logic to treat both absent and empty
values for action_ns and default as needing their fallback values, while
emitting each YAML key only once. In

lines 193-199, make this change in the output loop; in
moveit_setup_assistant/moveit_setup_controllers/test/test_controllers.cpp lines
205-206, update expectations so empty inputs produce follow_joint_trajectory and
true.

Generate defaults for empty fields. The writer emits an empty action_ns and omits an empty default, so blank UI fields do not produce the required defaults. The PR objective requires defaults for blank fields; this repeats the prior review finding.

  • moveit_setup_assistant/moveit_setup_controllers/src/moveit_controllers_config.cpp#L217-L220: Treat absent and empty values alike, then emit each FollowJointTrajectory default once.
  • moveit_setup_assistant/moveit_setup_controllers/test/test_controllers.cpp#L206-L206: Expect "follow_joint_trajectory" and "true" for empty values instead of asserting that default is absent.

Update the FollowJointTrajectory writer’s empty-value handling in the controller
configuration code to treat absent and empty fields alike, emitting each
required default exactly once. In the test at
moveit_setup_assistant/moveit_setup_controllers/src/moveit_controllers_config.cpp
lines 217-220, verify the empty fields produce the action namespace default and
"true" for default; at

206, expect those values instead of asserting that default is absent.
