Description

Edit conflict not detected in following case

User A starts editing section
User B starts editing another section on same page
Bot C edit page
User A clicks 'save' -> edit conflict (with Bot-edit) detected -> User A starts solving conflict on page
User B clicks 'save' -> edit conflict (with Bot-edit) detected -> User B starts solving conflict on page
User A saves page -> all right
User B saves page -> edit conflict with user A not detected -> changes of user A reverted without hint

Could be a general problem in case of 3 involved persons, but case above is what happend.

If not allready happend, maybe include version-ID of conflict-edit in save operation (on edit conflict page) to prevent this.

So what you're saying is, when we have the user resolve an edit conflict, we don't account for a further separate conflict?

thats what i suppose - but im not sure about it
