Bug report #15808
Updated by Harrissou Santanna about 6 years ago
I don't know if it's a feature request or a bug but when setting the rotation/offset field for a symbol, from the data-defined widget, if you select the field in the list of proposed fields, all is ok. But if instead, you use the expression widget to set the same field (and only the field, no custom expression), it doesn't work.
QGIS returns "The selected point does not have a rotation/offset attribute set"
