Perspective Table Embedded Dropdown – onActionPerformed Script Error

Ignition
1

Hi team,
I’m using an embedded view with a dropdown inside a Perspective table column. When I attach a script to the dropdown’s onActionPerformed event, the Gateway logs an error during execution. I’ve verified the dataset tag path and parameters, but the issue persists. Any guidance would be appreciated. This stopped the other buttons’ function also.

def runAction(self, event):
    
    #self.getSibling("Label").props.text= str(self.view.params.column)
    tagPath = "[default]ds_cutlist"
    rowIndex = self.view.params.rowIndex   
    columnName = self.view.params.column

Thanks in advance.

It looks like you have a data key that begins with a number (1st). Those are not valid and can be problematic.

I’ve checked further, and the same issue also occurs when clicking the embedded view button that moves the current row one step up.

def runAction(self, event):
	# Compose message based on action	
    tagPath = "[default]ds_cutlist"
    rowIndex = self.view.params.rowIndex
   
    if rowIndex <= 0:
        return

    # Read dataset
    ds = system.tag.readBlocking([tagPath])[0].value
    pyDS = system.dataset.toPyDataSet(ds)
    rows = [list(row) for row in pyDS]

    if rowIndex >= len(rows):
        return

    rows[rowIndex - 1], rows[rowIndex] = rows[rowIndex], rows[rowIndex - 1]
  
    headers = list(ds.getColumnNames())
    newDs = system.dataset.toDataSet(headers, rows)
   
    system.tag.writeBlocking([tagPath], [newDs])
