Hey @mark-bathori thanks for the update! I agree with the problem and the
general approach. The only concern that I have here is with the new
`ValidationResult` class. Specifically, I don't think it makes sense to create
a `ValidationResult` and then call `add_validation_result` on that object. I
would also like to avoid having to create a `ValidationResult` just to call
`build_validation_result_list()` just in order to return it.
Rather, I think we should define `ValidationResult` to have an `init` that
takes those 4 parameters (`subject`, `valid`, `explanation`, input`) and just
return a `list` of them from the method. For example, we should be able to
implement the above as:
```
def customValidate(self, context):
results = []
results.append(new ValidationResult(subject="Test subject 1",
explanation="Test validation 1", valid=False, input="Input 1")
results.append(new ValidationResult(subject="Test subject 2",
explanation="Test validation 2", valid=False, input="Input 1")
return results
```
Or, alternatively,
```
def customValidate(self, context):
return [
new ValidationResult(subject="Test subject 1", explanation="Test
validation 1", valid=False, input="Input 1"),
new ValidationResult(subject="Test subject 2", explanation="Test
validation 2", valid=False, input="Input 1")]
```
The `PythonProcessorAdapter`, then, should be responsible for taking that
Python `list` that is returned and converting it into the `ArrayList` needed by
the framework.
