UI_E_TRANSITION_NOT_IN_STORYBOARD
UI_E_TRANSITION_NOT_IN_STORYBOARD belongs to Windows Animation Manager. It marks an operation referenced a transition that was never added to the target storyboard. The useful starting point is the exact API, object and state transition that returned 0x802A0107, because a shell or application message can hide that boundary.
Where this result is raised
The pointer can be valid and owned by the right manager yet still have no membership in this storyboard. Priority comparisons, keyframe relationships, or removal operations must use the exact transition instance already inserted.
Evidence worth collecting
- Target storyboard identity.
- Transition identity.
- Successful AddTransition history.
- Operation requiring membership.
A controlled diagnostic sequence
- First: Check the AddTransition HRESULT.
- Next: Keep returned transition identity with its storyboard record.
- Then: Reject stale transitions after rebuilding the graph.
- Finally: Enumerate the construction sequence in logs.
How to interpret comparison tests
| Control | Interpretation | Hold constant |
|---|---|---|
| Same operation, controlled environment | If the result follows one machine, account, volume, network, or device, environment matters. | Keep versions and identity explicit rather than comparing only the final message. |
What this code does not justify
UI_E_TRANSITION_ALREADY_USED indicates membership elsewhere or earlier; NOT_IN_STORYBOARD means membership is absent here.
Do not search by equivalent duration or final value and substitute another transition.
Verification after correction
Treat it as corrected only when the exact inserted transition is used for subsequent relationships and stale identities are rejected; retain the original negative case so fallback cannot be mistaken for repair.
