AttributeError: 'NoneType' object has no attribute 'motorNumber'

Ignition

I have a popup window that is throwing errors when it is opened. motorNumber is a custom property that is defined in the custom properties for the window. Does anybody know what would cause this?

Below is a full stack trace.

Please show the code. Note that the report says the error is in line #6.

3

Line 6 of your code has something.motorNumber. The problem is something is not found (NoneType). Based on the information provided, you likely want to find it like this:

event.source.motorNumber

event.source gets the clicked object “Root Container” and .motorNumber gets the custom property on the root container.

Sorry for the delay, I’ve been traveling the last few weeks. Here’s the code that was generated by the designer on my spinner object.

# This script was generated automatically by the navigation
# script builder. You may modify this script, but if you do,
# you will not be able to use the navigation builder to update
# this script without overwriting your changes.

param1 = event.source.intValue


window = system.nav.openWindow('Popups/MotorPopup', {'motorNumPopup' : param1})
5

That’s not the code which generated the error you posted previously.

6

I guess I’m not sure where to look then. The error occurs when I click on the spinner object which is supposed to open a popup window by passing through the custom parameter. Everything I’ve done was configured using the designer.

7

You need to look on the Root Container in the mouseClicked Event. At least, that’s according to the logging you posted.

8

The original error says the flaw is in the mouseClicked event of the root container. Please show that code. In the popup, perhaps.

I’ve managed to get this working by switching the template to use UDT tags. Not sure what I did wrong before but thanks for all of the help.
