#20113 closed defect (wontfix)

Create/Update Multipolygon: Cancel in relation editor has different result compared to common relation edtior

Reported by: skyper Owned by: team
Priority: normal Milestone:
Component: Core Version: latest
Keywords: template_report create multipolygon cancel relation editor Cc:


What steps will reproduce the problem?

  1. Have a closed way with one linear tag and an area tag
  2. Create MP
  3. In the relation editor click "Cancel" or press Escape

What is the expected result?

The complete action is canceled.

What happens instead?

In my case, without changes in the relation editor, it is the same behavior as clicking on "OK"
Only the possible adjustments are canceled.

Please provide any additional information below. Attach a screenshot if possible.

Update MP shows the same behavior.

This behavior is the complete opposite to the behavior when opening the relation editor from other places., especially, compared to "Create new relation" and "Create copy of relation".

Isn't this a duplicate of #19966? No, but as long as that ticket is open I would not use the feature.
Besides that the behaviour is similar to creating a relation from presets, isn't it?

With preset -> relation -> multipolygon -> new relation, I get the common dialog for "unsaved changes" and the relation is not created with No, discard the changes and close. That is ok and the same as "copy relation" and "edit relation" or "add relation" with at least one change in relation editor. Looks pretty consistent to me.

I have started updating the docu on Help/Action/UpdateMultipolygon and Help/Action/CreateMultipolygon. What does multipoly.alltags do?

comment:3 Changed 11 days ago by GerdP

I also searched for a docu today ;)
Didn't try it, but looking at the source it's about tags which don't appear in all outer ways. If set to true, tags which appear only in some outer ways might be moved to the relation.
Probably depends on the patch for the bug shown in #20110.

Reg. "cancel": I see no simple way to change the behaviour if way tags are changed. It's far easier to remove the code which opens the relation editor.

Mmh, should have looked at the source code from the beginning. The relation editor is a "normal" editor ("edit Relation") and the preference setting just a shortcut to not have to open the just created/updated multipolygon, manually. I thought it is placed inside the action.

So it is no inconsistent behavior but needs a proper documentation. Still have the opinion that it is a dangerous clinch as my expectation was that I am still within the action and removing tags from the relation might even restore them on the ways.

Searching through, I do not find the notifications Intersection between multipolygon ways or Multipolygon is not closed but only ones which are not shown to user. Where do I find the notifications?

Where do I find the notifications?

The calculation is done with the code in the validator, see makeFromWays() in

Thanks, this should then be documented on a different page anyway, as these notifications are used by different actions.

Totally forgot about #19966. Atm, this relation editor is modal and blocks all other actions. So it is not a "normal" relation editor and quite limited.

comment:9 Changed 10 days ago by GerdP

Yes, I tend to think I should simply commit the patch for #19966 now.
