UI - Clear all mapped index for a mapped TI

[pierrejeambrun]

Description

It is not possible to clear all mapped task instances at once for a specific TI.

In the UI here I think it would be nice to have a 'clear all mapped task' button. The backend endpoint to clear a TI already supports this.

    task_ids: list[str | tuple[str, int]] | None = Field(
        default=None,
        description="A list of `task_id` or [`task_id`, `map_index`]. "
        "If only the `task_id` is provided for a mapped task, all of its map indices will be targeted.",
    )

Hi! I’d like to work on this issue., if it's still available.
Since the backend already supports clearing all mapped task instances by task_id, I’ll focus on adding the corresponding UI action to clear all mapped TIs at once.
I’ll keep the implementation aligned with existing “clear task” UI patterns. Thanks!

Hi, I've set up my development environment and reproduced the scenario with mapped tasks. I can confirm that the "Clear all mapped" button appears in the UI, but I need clarification on the expected implementation.

To make sure I'm on the right track, could you clarify a few things:

1. Is this exactly the requirement you had in mind and is the UI fine?
2. When clicked, should it open a dialog similar to the existing clear dialog with options for upstream/downstream/past/future, or should it clear immediately?
3. Should this button replace the existing "Clear Task Instance" button for mapped tasks, or should it be an additional button alongside it?

Could you please assign this issue to me so I can take the time to debug and implement the required functionality properly?

Thanks!

@rachanadutta please go ahead, I just assigned you.

@vishakha1411 You are looking at a particular map index. This issue is for the mapped summary and to clear all of the corresponding map indexes at once. (cf screenshot)

@pierrejeambrun Thanks! I’ll get started on this and will share a PR soon.
