I have just upgraded to Oxygen 18 only for this awesome image map editor feature. I am following all the steps mentioned here: https://www.oxygenxml.com/doc/versions/18/ug-editor/topics/image-map-dita.html, but moment I click OK, to create image map for my image, I get the following error:
Could not create AuthorDocumentFragment. Cause: Attributename “null” associated with an element type “imagemap” must be followed by the “ = “ character.
Please help, I am not understanding why this error message keeps displaying every time I try the feature.
