[Betternestedset-talk] BetterNestedSet + ":dependent => :destroy" = BUG ?

[Tom]

Hi there,

I use the plugin "BetterNestedSet" for a model and need to have the 
model option ":dependent => :destroy" at the same time.

Using only one of these two things works perfectly. But using both at 
the same time keeps throwing an error.

I have the following model structure (which is part of a slightly bigger 
structure):

class Group < ActiveRecord::Base
 has_many :groupmessages, :dependent => :destroy
end

class Groupmessage < ActiveRecord::Base
 belongs_to :group
 acts_as_nested_set :scope => :group_id
end

I need to delete a group and all its "groupmessages" with it (using on 
the above ":dependent => :destroy").
But when I try to do it like this: Group.destroy(groupIdHere), I get the 
following error...

ActiveRecord::RecordNotFound in GroupController#delete
Couldn't find Groupmessage with ID=61

...but the groupmessage with the ID=61 is definitely in the database! 
(Btw, it's a "child" groupmessage)

Group.destroy(groupIdHere) works only if I delete "acts_as_nested_set 
..." in the Groupmessage model.

What can I do to make it work??
Thanks a lot for your help on this problem!
Tom
