Why do I get a runtime error

Elm Virtual Dom diffing algorithm tries to remove the contentEditable property by doing:

node.contentEditable = null;

which is not supported for contentEditable.

You can produce the same error by doing in a javascript console:

document.body.contentEditable = null

This is a known bug traced here: bug #104 (specifically #81)

I guess that the work-arounds are:

  • use attribute "contenteditable" instead
  • or set the property to Encode.bool False instead of removing it from your attributes
  • or use Html.Keyed with a different identifier to force the div to be rebuilt
