What this guide covers
Remove an unfinished canvas signature before confirmation. This guide follows the supplied Delivery Note module’s live hooks, controller actions, model rules, views and stored side effects.
Exact step-by-step process
- Draw the signature.
- Select Clear before submitting.
- Confirm the canvas is blank.
- Draw the correct signature.
- Select Confirm Delivery only when satisfied.
Fields, choices and supported possibilities
- Clear button calls the Signature Pad clear method
- No server record is changed until the form is submitted
Code-backed validations and workflow rules
- Clearing affects only the current browser canvas.
- It does not create a sign_failed event.
- After a successful submit, the note is signed and the canvas workflow is no longer available.
Expected result and verification
- Only the final submitted signature is stored.
Checks, security and troubleshooting
- Do not reload or close the page before submitting if the signature is still needed.
Stay within the supported flowDo not force database values, expose secure tokens, bypass permission checks, replace a stored signature or invent a status or interface that the supplied code does not implement.
