remove_viewmodel
DestructiveIdempotent
Removes a named ViewModel context from a Widget Blueprint's MVVM authoring state; already-absent contexts succeed idempotently.
Instructions
Remove a UMVVMViewModelContext (by context name) from a Widget BP's MVVM authoring state. Inverse of add_viewmodel; idempotent (already-absent is an honest success).
Returns: { widget_blueprint_name, context_name, already_existed, removed, view_model_count, has_mvvm_extension, saved, save_error? }
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| force | No | Optional. This command is REFUSED while a Play-in-Editor session is running: it either compiles a Blueprint (the reinstancer can retain a world, and CheckForWorldGCLeaks is Fatal -- it KILLS the editor) or writes to disk (Editor.AllowSavingAssetsDuringPIE=0 makes the engine refuse the write, so it would report success without writing a byte). Stop PIE and retry instead; force=true runs it anyway, at your own risk. | |
| context_name | Yes | FName identifying the context to remove (idempotency key) | |
| widget_blueprint_name | Yes | /Game path of the Widget Blueprint asset (string) |
