Section Persistence events listeners uses static variables and this is misleading

[galou]

In Section Persistence events listeners the documentation may lead the workbench developer to understand that classes with the @proxy decorator are dataclasses. However, the variables var1 and var2 are static and this is for sure not what the developer wants.

Why do you think that var1 and var2 are static? They are not.

class A:
  var1: int
  def __init__(self, v: int):
     self.var1 = v   # Sets a non static var in self instance
     A.var1 = 0      # Sets a static var in A class

Check

>>> a = A(1)
>>> b = A(2)
>>> 
>>> a.var1
1
>>> b.var1
2
>>> A.var1
0
>>>

Sorry, my mistake. I overlooked that var1 and var2 at the class level are just type hints and not an assignment. By the way since A.var1 and self.var1 are different variables, isn't the type hint documenting a different variable when used at the class level?

Well, python type hints are not strong declarations as in other languages. They are there just to aid the linter, autocomplete and static analysis.
