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
Windows Animation is a stateful COM subsystem., animation variables, transitions and storyboards are created under a manager, scheduled against a monotonic animation time, updated before drawing, and eventually sealed or released. During a this result investigation, a visible glitch can therefore be downstream of a lifecycle, ownership, timeline, callback, or numeric contract failure.
When it is returned, the pointer can be valid and owned by the right manager yet still have no membership in this storyboard. During a this result investigation, priority comparisons, keyframe relationships, or removal operations must use the exact transition instance already inserted.
The first owner to inspect is the animation manager, storyboard, transition, timer, or callback that returned the HRESULT.
Evidence worth collecting
- Target storyboard identity. for this HRESULT, this pins the event to an object or resource generation within the Windows Animation Manager boundary.
- Transition identity. for this HRESULT, this places the event on the lifecycle or transaction timeline within the Windows Animation Manager boundary.
- Successful AddTransition history. for this HRESULT, this separates caller input from environment and service state within the Windows Animation Manager boundary.
- Operation requiring membership. for this HRESULT, this creates a stable comparison across retries or another machine within the Windows Animation Manager boundary.
A controlled diagnostic sequence
During a this result investigation, reduce the case while preserving the condition described by the HRESULT.
- 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 input, fresh object or connection | If the result disappears, retained lifecycle or ownership state is implicated. | While diagnosing this result, keep the original data, account, device, or timeline parameters unchanged. |
| Same object, reduced operation | If the result follows one specific transition, statement, file, or ceremony step, the failure is localized. | While diagnosing it, remove only unrelated work and keep the first failing boundary visible. |
| Same operation, controlled environment | If the result follows one machine, account, volume, network, or device, environment matters. | While diagnosing it, 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.
