Adding new properties to component

Dash Python

Hi,

I’ve used the following lines to add properties to components that can be used in callbacks:

  def add_property(self, property_name, property_value=None):
      """Add a property to the component that can be read/fetch by callbacks

      Parameters
      ----------
      property_name : str
      property_value : int or float or str or bool

      """
      # Add a property
      self.__setattr__(property_name, property_value)
      self.add_property_name(property_name)

  def add_property_name(self, property_name):
      available_properties = self.__getattribute__("available_properties")
      available_properties.append(property_name)

      prop_names = self.__getattribute__("_prop_names")
      prop_names.append(property_name)

It used to work however, now I got “Invalid prop for this component” Error while it’s working and it ignores the

prevent_initial_call=True

in the callback.

Is there another way to add properties to components or to prevent this error?

Thank you for your answers.

Best regards
