I apologize if the answer is already on here but I did a pretty good search.

if I change the number and then hit enter I want to popup and ask Yes, No then proceed or exit.

```python
def runAction(self, event):
	system.perspective.print(message='Key ' + event.keyCode + event.key, destination="all")
	self.session.custom.newSequenceNumber = event.keyCode
	if event.key == '\n':
		system.perspective.openPopup("messageBox",'ChangeSequence', title='Key ' + event.keyCode + event.key, showCloseIcon = True)
	else:
		system.perspective.openPopup("messageBox",'ChangeSequence', title='Key ' + event.keyCode + event.key, showCloseIcon = True)
		
		#system.perspective.openPopup("messageBox",'Popups/MessageBox', params = {'message':self.getSibling("TextField").props.text})

```

So I have this Table that I want to run this script on but want to ask yes or no to first.  
I am have problems opening popup or even printing to console's

```python
|||
|---|---|
||def get_sequence_values(data):|
|| return [data.getValueAt(row, 'Sequence') for row in range(data.getRowCount())]|
|| |
||def get_sorted_indices(sequence_values):|
|| return sorted(range(len(sequence_values)), key=lambda k: sequence_values[k])|
|| |
||def get_row_values(data, row_index):|
|| return [data.getValueAt(row_index, col) for col in range(data.getColumnCount())]|
|||
||def swap_rows(data, row_index1, row_index2):|
|| if 0 <= row_index1 < data.getRowCount() and 0 <= row_index2 < data.getRowCount():|
|| if row_index1 != row_index2:|
|| row1_values = get_row_values(data, row_index1)|
|| row2_values = get_row_values(data, row_index2)|
|| # Delete the row with the higher index first|
|| if row_index1 < row_index2:|
|| data = system.dataset.deleteRow(data, row_index2)|
|| data = system.dataset.deleteRow(data, row_index1)|
|| data = system.dataset.insertRow(data, row_index1, row2_values)|
|| data = system.dataset.insertRow(data, row_index2, row1_values)|
|| else:|
|| data = system.dataset.deleteRow(data, row_index1)|
|| data = system.dataset.deleteRow(data, row_index2)|
|| data = system.dataset.insertRow(data, row_index2, row1_values)|
|| data = system.dataset.insertRow(data, row_index1, row2_values)|
|| return data|
||def adjust_sequence_values(data):|
|| for row in range(data.getRowCount()):|
|| data = system.dataset.setValue(data, row, 'Sequence', row + 1)|
|| return data|
||newValue = event.value|
|||
||columnName = event.column|
||data = self.props.data|
||maxSequence = max(get_sequence_values(data))|
||if columnName == 'Sequence' and newValue is not None:|
|||
|| if newValue <= maxSequence:|
|| originalSequenceValues = get_sequence_values(data)|
|| newData = system.dataset.setValue(data, event.row, columnName, newValue)|
|| newRowIndex = originalSequenceValues.index(newValue)|
|| if newRowIndex != event.row:|
|| newData = swap_rows(newData, event.row, newRowIndex)|
|| newData = adjust_sequence_values(newData)|
|| self.props.data = newData|

I think this sort of thing is a lot easier to do when you make your editable columns into embedded views. If you're unfamiliar with that process, I have a video on it [https://www.youtube.com/watch?v=xQiiJkSnrvg](https://www.youtube.com/watch?v=xQiiJkSnrvg)

Ultimately, with an embedded view you can forget about keyboard events altogether and either use an onActionPerformed event or a change script on the component to open a confirmation popup after the field is edited.
