Thanks again.
I have to spend more as it didn't work again.
I even found some sample within the tryton code based on your
comments(sale line 960)
surprisingly my module works fine and fields can be visible or enable
based on the other fields on the same model.
I have got this error when i want to change child fields as well. for
example changing a field in the parent based on the child field.
As referring to the exact field in the child model doesn't work, I put
only a name of the one2many field to refer to this model.
Therefore when a user tries to add anything to the child model it
triggers visibility of the fields in the parent model.
i did some changes inside the module maybe the error was because of
them.
Name of the relational fields are not the same as the class (unlike
all the examples of Tryton like sale.py)
I change the def module of the sub class to this :
def create(self, cursor, user, values, context=None):
#vals['code_length'] = len(vals['code'])
val = values.copy()
val['active'] = True
return super(product_price_list_main, self).create(cursor,
user, val, context=context)
rec_name is generated dynamically.
There are lots of underline "_" in my classes name.
It's very strange for beginners like me.
I hope one of the above information was the cause of error.
Otherwise i really get confused as i don't have anything to change !
Regards.
class model1()
_name='company.model1'
*multiprice *= fields.Boolean("Multi Price allowed?"
mod2 = fields.one2many(model2 ...etc...)
class model2()
_name='company.model2'
mod1ref = fields.many2one(model1 , ...etc...)
STATES = {
'invisible' : Bool(Eval('_parent_model1.*multiprice*')),
}
But still having problem
