I am using a MutationObserver to watch a node in the DOM got changes to its size.
I attach this to a particular DOM node by its id. The model then changes and Elm re-renders the view. Unfortunately the DOM node seems to be deleted then completely replaced by a new one with the same id. I tried Html.Keyed to hint that the same node should be re-used, but no luck with that. It would be very helpful to get an understanding of the criteria under which a DOM node will be completely overwritten. I did have this working at one point, but refactored a lot of stuff since then, and now it is broken. The actual code is this: div [ class "editor-inline__wrapper" , id <| "inline__wrapper" ++ asUUID contentModel ] [ content ] Where 'content' can be is rendered through a number of different code paths, depending on whether it is currently selected, and whether it is currently edited. It takes its value from this: content = mapWhenWithSelectedModel (\selected -> if (asUUID selected.contentModel == contentId) then case (Overlay.editedValue selected.overlay) of Just value -> markdownView <| withMarkdown contentModel value Nothing -> markdownView contentModel else markdownView contentModel ) mode |> Maybe.withDefault (markdownView contentModel) All I need is for the DOM rendering to use the same div to wrap this content, as the content itself changes, so that it can be observed. -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
