Funny behavior of fields.Char which I dont understand

[bromoapp]

I have this model with unique_id field as below:

class ProjectTask(ModelSQL, ModelView):
    "Activity"
    __name__ = "afx.project.task"
    _rec_name = 'activity'

    unique_id = fields.Char("Uuid")

I set the value using random string, so the value of unique_id = “709f653bbe36ee26502b1a9f9e08828b54540f75794f91b3b8214ea65aadfdab” successfully during creation.

Then I use it in this code block:

existing_project_task = ProjectTask.search([
      ('unique_id', '=', cls.unique_id),
])

And always throws error:
An error occurred while processing record 5: 'bool' object is not callable

Anybody knows?

I do not know how you defined the method having this code but usually cls is for class so cls.unique_id is the fields.Char instance and not the database value.

I do not see how this can be triggered but it will be easier to understand with the traceback.
