Description

Discussion at http://osgeo-org.1560.x6.nabble.com/QGIS-Developer-Rotate-or-Offset-Point-symbol-how-do-they-work-Or-are-they-broken-tt5382677.html

In the data-defined widget, it looks like selecting a field from the "Fields type" menu does not have the same consequence as using its "Edit..." menu and write an expression with only the field name. While both are applied to the property, using interactive tools like "rotate point symbol" or "Offset point symbol" and maybe others...: in the first case, modification on canvas updates the field, in the latter you only get message like "The selected point does not have a rotation attribute set." eg.
