DatumSource struct makes the script input to be reference input

[jmagan]

Hello

I'm facing some troubles when I'm trying to build a transaction. The script UTxO has an inline datum and I'm using txInputsBuilder.add_plutus_script_input. The datum is created as DatumSource::RefInput(input). Maybe I'm wrong, but I understand that when I create a datum as ref, I'm really indicating an inline datum not a reference input.

This DatumSourceis pattern matched in the get_ref_inputs:

pub fn get_ref_inputs(&self) -> TransactionInputs {
        let mut inputs = Vec::new();
        for wintess in self.required_witnesses.scripts.iter()
            .flat_map(|(_, tx_wits)| tx_wits.values())
            .filter_map(|wit| wit.as_ref()) {
            match wintess {
                ScriptWitnessType::NativeScriptWitness(NativeScriptSourceEnum::RefInput(input, _, _)) => {
                    inputs.push(input.clone());
                },
                ScriptWitnessType::PlutusScriptWitness(plutus_witness) => {
                    if let Some(DatumSourceEnum::RefInput(input)) = &plutus_witness.datum {
                        inputs.push(input.clone());
                    }
                    if let PlutusScriptSourceEnum::RefInput(input, _, _) = &plutus_witness.script {
                        inputs.push(input.clone());
                    }
                },
                _ => ()
            }
        }
        TransactionInputs(inputs)
    }

This is causing that my redeemer is adding for each inline datum a refence input. That makes fail my validator. Am I correctly understanding this DatumSource struct? How should I add Plutus Witnesses with inline datum?

By the way, there is a typo in the word witness in the rust script. It's typed as wintess.
