In vision, I am trying to open a window with a table row selection and pass a parameter from the row selection to the opening window. I am able to open the window but it doesn't pass the parameter to the tables custom property 'Date'. I have the same custom property 'Date' on the window where I am selecting the row from the table. Any ideas?

```auto
table = event.source 
if table.selectedRow>=0: 
    param = table.data.getValueAt(table.selectedRow, "DateOnly") 
    system.nav.openWindow("Maintenance/Burner Off/Dryer 1 Burner Day History 
    {"Date": param})

```

This is a propertyChange event on the table? Perhaps try rewriting it like this:

```auto
if event.propertyName == 'selectedRow' and event.NewValue > -1: 
    param = table.data.getValueAt(event.newValue, "DateOnly") 
    system.nav.openWindow("Maintenance/Burner Off/Dryer 1 Burner Day History", {"Date": param})

```

_Note how this can only happen on one propertyChange event, and that a missing quotation mark on your window path as well as a comma seperating the path and the parameters have been added._

**Edit:** Removed an inadvertent enter after the widow path

I got it to work, I had to put the custom property on the window and not the new table. I added some print statements, then realized my error.

```auto
table = event.source

if table.selectedRow >= 0:
    param = table.data.getValueAt(table.selectedRow, "DateOnly")
    
    # Print statements for debugging
    print("Selected DateOnly:", param)
    
    windowPath = "Maintenance/Burner Off/Dryer 1 Burner Day History"
    parameters = {"Date": param}
    
    # Print statements for debugging
    print("Opening window with parameters:", parameters)
    
    system.nav.openWindow(windowPath, parameters)

```

I'm glad you got it to work, but please consider the script I offered. The best practice is to limit propertyChange event scripts to specific properties. The initial `if` statement for any propertyChange event should include the property name, and all scripting logic for that event should occur within that `if` statement. Otherwise that code will evaluate for every property that changes on the component.

Not just a "best practice". You will have numerous weird bugs if you fail to check `event.propertyName` for the property you need to monitor.

when I try your example I get a error

```auto
Traceback (most recent call last):
  File "<event:mouseClicked>", line 1, in <module>
AttributeError: 'java.awt.event.MouseEvent' object has no attribute 'propertyName'

```

I see; you are using the mouse clicked event. I use the propertyChange event for this sort of thing, so I had imagined that's what you were using.

got it, changed it to property change script. Thanks for the help.
