When adding a new component, magnolia asks if the component should added at top or at bottom of the area.
If the dialog has a field (e.g. Text Field) with the name «position», it gets filled with either «top» or «bottom».
If the field is a select field with the values
- left (selected)
no value is selected when creating a new component, due the value of «position» is already set to «top» or «bottom». This behaviour leaded to many problems in our projects.
This value get also stored to the component, which makes absolutely no sense, due the component may be moved afterward.
