Viewing Replay Data

Replay lets you load past workflow execution data and step through it visually on the canvas. This is invaluable for understanding how a workflow actually behaved and for debugging issues.

Loading replay data

  1. Select an event node on the canvas (click on it).
  2. Click the reload button in the event's Property Panel.
  3. The modeler fetches the execution history from the backend.
  4. The Replay Panel expands to show the loaded data.

Loading replay data for an event node

Multiple executions

If the event has been triggered multiple times, the Replay Panel shows an entry selector dropdown at the top. Each entry includes:

  • Timestamp: When the execution occurred.
  • User: Who triggered it.
  • URL: The page URL at the time of execution.

Click an entry to view its execution steps. The dropdown is only shown when there are two or more entries.

The Replay Panel shows a list of execution steps. Each step represents one action in the workflow execution:

Step type Icon Meaning
Started Play icon The workflow began executing at this event.
Execute Arrow icon An action was executed.
Add successor Green check A condition passed; execution continued.
Ignore successor Red X A condition failed; this path was skipped.
Access denied Lock icon Execution was blocked by permissions.

Manual navigation

  • Click a step: Jump to that step. The corresponding node or edge is highlighted on the canvas.
  • Forward/Back buttons: Move one step at a time.

Auto-playback

  • Play: Start automatic playback through all steps.
  • Speed: Choose 0.5x, 1x, or 2x playback speed.
  • Pause: Stop auto-play at the current step.
  • Stop: Exit replay mode entirely and clear all highlights.

Canvas visualization

During replay, the canvas shows visual indicators:

  • Node highlighting: The active step's node is highlighted.
  • Edge indicators: Floating circles at edge midpoints show condition results:
  • Green circle with checkmark: Condition passed.
  • Red circle with X: Condition failed.

The canvas automatically pans to keep the current step's element in view, while preserving your zoom level.

Bidirectional sync

The replay system syncs in both directions:

  • Click a step in the Replay Panel --> the canvas highlights the corresponding element.
  • Click a node on the canvas --> the Replay Panel jumps to the first matching step.

Step metadata

Click the i button in a step's area to view detailed metadata:

  • Step type
  • Component ID
  • Successor ID (for edge-related steps)
  • Condition ID (for condition evaluations)
  • Error information (if applicable)

Empty state

When no replay data is loaded, the panel shows guidance messages explaining how to load data or run a test, depending on what capabilities are available.
