Embedded does not work correctly about yii2-multiple-input

[RodrigoDornelles]

Note

I did some tests, and realized that the "name" attribute is set correctly when used in columns, but only in a new model, when you go to edit another problem happens.

When create a new model

Works

echo MultipleInput::widget([
    'model' => $model,
    'attribute' => 'campos',
    'columns' => [
        [
            'name' => 'pergunta',
            'type' => 'textarea',
        ],
        [
            'name' => 'opcoes',
            'type'  => MultipleInput::className(),
            'options' => [
                'columns' => [
                    [
                        'name' => 'opcao'
                    ]
                ]
            ]
        ]
    ],
])?>

• name occurred Formulario[campos][1][opcoes][campos[1][opcoes]][0] should be Formulario[campos][1][opcoes][0]
• id occurred formulario-campos-1-opcoes-campos-1-opcoes-0 should be formulario-1-campos-opcoes-0

            ]
        ]

• id occurred formulario-campos-0-opcoes-item-item should be formulario-campos-0-opcoes-0-item

@RodrigoDornelles Hi, thx for the reproduce case. What version of the widget do you use?

@RodrigoDornelles I can't reproduce it without seeing the code of the model.

@unclead I did a hardcoded interim fix, this is sufficient for my specific case, but it could be a problem for other cases.

'value' => fn ($data) => isset($data['opcoes'])? $data['opcoes']['item']: null,

TBH I didn't manage to reproduce the issue so I can't say why it happens. Did you try to debug it? I mean go to the widget's code and try to figure out the root cause?

I tried debugging and solving, but i found the plugin much more complex than thought.

I'll still work hard on a system, notice anything, or if I can find the problem.

That's true. The result of years of incremental improvements. I'm working on refactoring it's architecture right now and it's quite complicated as well (even considering I did most of the features 😄 )
