      Vaadin does not provide one StringToEnumConvert by default so this is what one gets when trying to display an Enum property in a text field.

      Caused by: com.vaadin.data.util.converter.Converter$ConversionException: Unable to convert value of type info.magnolia.task.Task$Status to presentation type class java.lang.String. No converter is set and the types are not compatible.
	at com.vaadin.data.util.converter.ConverterUtil.convertFromModel(ConverterUtil.java:116)
	at com.vaadin.ui.Label.getDataSourceValue(Label.java:187)
	at com.vaadin.ui.Label.setPropertyDataSource(Label.java:260)
	at info.magnolia.ui.form.field.factory.AbstractFieldFactory.getView(AbstractFieldFactory.java:205)
	at info.magnolia.ui.dialog.formdialog.FormBuilder.buildView(FormBuilder.java:135)

      The fix consists in creating a simple Converter and add a check in AbstractFieldFactory.getView(..) (see attached patch)
