[structr-ui][2.0.1] Cannot save multi-line string in Edit mode

When press "enter" during string edit mode, a textarea will replace the input field.
Cannot save the changes after that.

After some investigation in structr-app.js, I found that the js is using the field "data-structr-attr" as object key, but the actual field is "data-structr-name".

Compatibility problem i guess?
