What I did

I created a table Pages with an hasMany association Images, the foreign key is "foreign_key", dependent and cascadeDelete are both true. The Image table on its own has a hasMany association Translations, the foreign key is "foreign_key", dependent and cascadeDelete for this association are also true.

What happened

When I try to delete a Page I got the "column foreign_key in where clause is ambiguous" exception.
The exception is thrown from the DependentDeleteHelper.
The created conditions are lacking the table aliasses.

What you expected to happen

That deleting a page also triggers the callbacks for deleting an image and that image its translations
