View source for Documentation:Action must have a name

<message>Write the content here to display this box</message>
If you get this model error message, an action has been orphaned in your model. For example, a Class has been deleted, but, for some reason, the Class action belonging to it was left behind.

To remove actions without a name, open the OCL debugger for the model itself by right-clicking on a diagram background and selecting Extras -> Open model debugger...
# Make one (probably the only one) of the expressions there an Action (1)
# Paste the code below (2)
# Execute it using F5 or the button (3)
 AbstractAction.allInstances->select(aa|aa.Name.isNullOrEmpty).delete
Close the dialog and save your model as usual.
