TreeView input field not working

Hi!

I created a TreeView with MultiColumnHeader and it works fine for showing the information that I need.
Although, my problem is with the editing / using input fields.

I have two columns, for example some key - value pairs and I want to edit the value field inside this TreeView.
I tried with multiple TextFields, like EditorGUI.TextField, EditorGUILayout.TextField or DelayedTextField, but the result was the same.
The field is there visually and I can select any line / row, but the input field not get the focus (or at least this is what I see) and not recognize any keys, in this way I’m not able to change the value of this input field.

I couldn’t find any clue what I missed or how it can work. I already checked this manual Unity - Manual: TreeView.

Here is the main part of my code for this:
Code

protected override void RowGUI(RowGUIArgs args) {
if (Event.current.rawType != EventType.Repaint)
            {
                return;
            }
    for (int i = 0; i < args.GetNumVisibleColumns(); i++) {
        CellGui(args.GetCellRect(i), (Column)args.GetColumn(i), ref args);
    }
}

private void CellGui(Rect cellRect, Column column, ref RowGUIArgs args) {
    CenterRectUsingSingleLineHeight(ref cellRect);
    Translation translation = data.translationList[args.item.id - 1];
    switch (column) {
        case Column.Key:
            DefaultGUI.Label(cellRect, translation.key, args.selected, args.focused);
            break;
        case Column.Translation:
            // Not get the focus when clicked on it, cannot edit the field, cannot recognize any key press, etc.
            translation.translation = EditorGUI.DelayedTextField(cellRect, translation.translation);
            break;
}}

Here is an example image:

Nevermind, I found what caused my issue and prevent the actions to receive in the input fields.
If you have a simple treeview and the input fields are not react to the interactions, it worth to just check the flow and events.

I just simply blocked the events with this line in the RowGUI method:

if (Event.current.rawType != EventType.Repaint)
{
    return;
}

It was my mistake to mess with this, but maybe somebody will end up in the same situation.
