Fixes #3434
Fixes #3314

Что сделано:
Оригинальный PR #2959 удалил генерацию ключей action_ns и default по умолчанию для контроллеров FollowJointTrajectory, чтобы избежать дублирования, если пользователь ввел их значения в UI. Однако это привело к тому, что если поля остаются пустыми, эти ключи вообще не генерировались в moveit_controllers.yaml, что ломало работу Simple Controller Manager (ему требуется action_ns).

Теперь ключи добавляются условно, если их нет в параметрах (или если они пустые), и пустые параметры отфильтровываются при выводе YAML-узла.

Как проверено:
Локальное окружение не содержит colcon/ROS 2/clang-format для выполнения тестов, однако был добавлен C++ unit-тест OutputMoveItControllersFix3314, который проверяет логику работы с пустыми и непустыми параметрами (имитируя UI).

Summary by CodeRabbit

  • Bug Fixes
    • Generated FollowJointTrajectory controller configuration now defaults the action namespace to follow_joint_trajectory and the default setting to true when those values are absent.
    • Explicitly provided values are preserved. Empty action namespaces remain empty, while empty default settings are omitted.

📝 Walkthrough

Walkthrough

Controller YAML generation now adds action_ns and default for FollowJointTrajectory controllers when those parameters are absent. It omits empty parameter values except action_ns. Tests cover missing, empty, and explicit values.

FollowJointTrajectory YAML defaults
moveit_setup_assistant/moveit_setup_controllers/src/moveit_controllers_config.cpp, moveit_setup_assistant/moveit_setup_controllers/test/test_controllers.cpp
When action_ns or default is absent, generation adds follow_joint_trajectory or "true" for FollowJointTrajectory controllers. Empty values are omitted except for action_ns. Tests check missing, empty, and explicit values.

Leaving these fields blank still produces YAML without the requested defaults, so the setup assistant’s blank-field workflow remains incorrect. Resolve this before merging.

Explanation

Active issue #3434 requires controller generation to work when action_ns and default are blank or populated. writeYaml adds fallback values only when a parameter is absent. When both parameters are empty, it emits an empty action_ns and omits default. OutputMoveItControllersFix3314 explicitly expects this output, so it does not verify usable fallback values for blank fields. Populated values and absent parameters are covered. Closed issue #3314 supplies context only.

Resolution

Treat empty action_ns and default values as needing the appropriate fallback values, or otherwise emit valid working values for blank UI fields. Update the regression test to assert the generated blank-field output works and retain checks for custom values.

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.

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.
