[tryton] check create_uid of a One2Many field

[timschneider13]

Hi, 

I want to check a One2Many field if the creator of the dataset is the 
actual logged in user. I try with domain like the following, but this don't 
work. 
All user can see all datasets. How can i solve the Problem? 


aaaaa = fields.One2Many('own.class','bbbbb','aaaaa',domain=[
     ('create_uid', '=', Transaction().user)])



@classmethod
   def __setup__(cls):
       super(Hshn, cls).__setup__()
      
       cls._buttons.update({
               'btn1': {
                   #'readonly': Eval('like_state') != 'like',
                   'readonly': Eval('aaaaa',[0])
                   },
               })
