I am trying to edit a Power Table which has been successfully populated with data merged from a couple of CSV files.

```auto
def UpdateParamEditTable():
	import system
	import sys
	
	window = system.gui.getWindow("Main Windows/ParameterEdit")	
	
	# A new recipe or stations selection has been made. Clear the table.
	tbl = window.rootContainer.getComponent('ptblParams') # The Power Table.
	customizer = tbl.columnAttributesData # Save the customizers before we destroy them ...
	# The line above destroys the tblParams customizers which includes the "editable" property of the Setpoint column.
	tbl.columnAttributesData = customizer # This line restores the customizer. 
	rows = [] # Empty.

	# Code to read the CSV file into rows[] goes in here.

	header = ['Line', 'Description', 'Setpoint', 'Min', 'Max'] # Header rows for the table.
	tbl.data = system.dataset.toDataSet(header, rows) # Create the table dataset.
	# This works. The table is populated with the CSV data.

```

So far, so good. The Power Table is populated correctly.

![Ignition Power Table data](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/f/eff5945e4fd48befe0249ee5f75ed2e27e7be317.jpeg)

The Power Table _onDoubleClick_ code starts as follows:

```auto
def onDoubleClick(self, rowIndex, colIndex, colName, value, event):
	# Power Table double-click event.
	table = system.gui.getParentWindow(event).getPathForComponent(self)
	data = system.dataset.toDataSet(table.data) # Line 16.

```

I’m getting an error:

```auto
  File "<extension-method onDoubleClick>", line 16, in onDoubleClick
AttributeError: 'unicode' object has no attribute 'data'

```

which seems to indicate that the system thinks the Power Table is empty when it is clearly well populated. I’ve tried using _system.dataset.toPyDataSet_ but receive the same error.

What am I not understanding here?

getPathForComponent() returns a string representing the path to the given component, not the component itself.

There are two functions which are very similar in name but return very different things.

```auto
#signiture for getPathForComponent()
java.lang.String getPathForComponent(java.awt.component c)

#signiture for getComponentForPath()
javax.swing.JComponent getComponentForPath(java.lang.String path)

```

It is not that the system thinks the Power Table is empty but that table is not the object you think it is.

Try the following:

```auto
def onDoubleClick(self, rowIndex, colIndex, colName, value, event):
     # Power Table double-click event
     table = event.source
     data = table.data

```

With extension functions you can access all scripting properties with self.propertyName.

Try changing these two lines:

```auto
table = system.gui.getParentWindow(event).getPathForComponent(self)
data = system.dataset.toDataSet(table.data) # Line 16.

```

to this 1 line:

```auto
data = self.data

```

I see the confusion with trying to use the event parameter because in other cases event is the calling object. I always reference the manual and it looks like the event parameter for the onDoubleClick is the mouse events.

Snippet from the manual:

Psssst!

```auto
    table = self

```

He could use this as per @pturmel suggestion :

```auto
table = self
data = table.data

```

@code_skin’s _data = self.data_ worked for me.

Phil’s _table = self_ looks interesting but came in late.

@Irose’s code gave me more attribute errors which I didn’t pursue.

Thank you all. I don’t do enough of this to become proficient and get rather confused sometimes.

I was kind’a hinting that the `table` variable wasn’t needed at all…

Ahh. That hint went over my head for some reason lol.
