creation of way without tag

[Mahabarata]

Hi,

I have created a multipolygon relation with 2 members : https://www.openstreetmap.org/relation/13958872/history
One member with no tag is the outer, the other with some tags is a inner.

• with Potlatch 3, I select the outer way
• on the left, I select "members"
• under, I select in the list "way 1043459092"
• above, in the relation table, I click on the cross to remove the way from the relation
• I save

No warning, no error : the save is sent.

Result :
the way outer had no tags. It is no more member of the relation so we have an empty way (no tag) in the osm database

Thank you but this is not a bug. Potlatch 3 doesn't have a validator. If you would like it to have a validator you're welcome to build one, or - in case someone else wants to build it - to create a single ticket enumerating cases that it could trap.

Hi,

I don't understand : try this with the example above =

• select one node of the inner way and delete it
• do the same for all the nodes of the inner way
• save

You will have a message = "Error :
An unexpected error occurred, probably due to a bug in Potlatch 2. Do you want to retry? (The server said: Precondition failed: Way 1043459093 is still used by relations 13958872.)"

If you have no validator, from where comes this message ?
Best regards

From the server.

Yes, I had understood that : in fact I found that iD editor has the same problem. Rather than to fix it with your editor and some others, I was thinking to fix it "on the server" should be better. But I don't know what it means : where is the "server" ? Where can I create an issue to propose to solve this problme there ? Is it on github ? on a talk ?
Maybe you know ?
Best regards
