Undo/redo on citations doesn't work correctly
Closed, ResolvedPublic
Actions

Description

  1. Change something in a citation.
  2. Click Undo.
  3. Click Redo.
  4. Click away. Why's that box still open?

It turns out that I can still edit (e.g., double-click another word and change its formatting), but I can't get rid of the box until I click the Cite button.

  1. Change something in a citation.
  2. Click Undo.
  3. Click Redo.
  4. Click away. Why's that box still open?
  5. Click the Edit button on the box. Now it won't open, and now I can't save, even if I can do basic text formatting.

Following the above steps, when you click redo, there are two separate errors:

Exception is inside TreeModifier, pinging @dchan

Esanders added a comment.Apr 28 2018, 10:14 PM

This bug has been present for at least a year, probably since TreeModifier was introduced, and possibly before that.

dchan added a comment.Apr 29 2018, 2:52 AM

Ooooh, this happens because ve.dm.TransactionBuilder#pushAttributeChanges( { key: val }, ... ) puts a live reference to val into the Transaction object. So if val subsequently gets mutated, that invalidates the Transaction object.

Sounds about right, I assumed this was a shallow copy issue.

Testing on the beta cluster, that seems to have fixed it.

I can still reproduce this on Beta cluster, re-opening it.

Ryasmeen added a comment.May 1 2018, 11:45 PM

Okay this does not happen when you try with basic reference but for all other types of citations it is reproducible 100% time.

dchan added a comment.May 2 2018, 9:10 AM

Hmm, thanks, it seems I overlooked that there are a few different ways reference-instead-of-copy can happen here - investigating further.

With change 430413, "change citation, undo, redo" seems to work fine in all the cases I've tried.

Great! Can we merge the fix now?
