Hi,  
I have a program node composed of two buttons and a textfield. Whenever I press the buttons their callback is invoked storing some parameters inside the DataModel.

```
undoRedoManager.recordChanges(new UndoableChanges() {
			@Override
			public void executeChanges() {
				model.set("param", value);
			}
		});

```

The data is stored and I can press the save icon (floppy disk). The problem happens when I change the textfield value the onOk() callback is invoked and the param is stored on the dataModel but the save icon is still greyed out and I can’t trigger the program save.  
I tried on the simulator and it works there. Any suggestion?

Thank you

@anon57702353  
I’m having the same issue with a JTextField, did you ever find a solution?

The other odd thing is that undo/redo buttons don’t see the setting of the text of a JTextField.  
In a URCap of mine I use both an `KeyboardInputCallback<Integer>` and a `KeyboardInputCallback<Double>`. The save button and undo/redo buttons both notice the change when an integer keyboard is called, but not when a double keyboard is called.  
The code for both keyboards is identical, here is the code from `onOk` for both:

Double keybaord:

```
@Override
public void onOk(Double, value)
{
    myView.getDoubleTextField().setText(Double.toString(value));
    model.set("double", value);
}

```

Integer Keyboard:

```
@Override
public void onOk(Integer, value)
{
    myView.getIntegerTextField().setText(Integer.toString(value));
    model.set("integer", value);
}

```

Certainly from this code I suspect that this is a bug with how polyscope triggers undoable changes?  
Though it is worth noting that `model.set(String, value)` is still triggering `isDefined()` just fine

EDIT: putting an `undoredoManager` inside `onOk()` has no effect.

Hello, Sam.  
Unfortunately I wasn’t able to find one.

Maybe someone can investigate this further.

Thanks,  
Federico
