Feeling Dumb With a Numeric Text Field

Ignition

So to get it out of the way, I am running 7.8.5. The simple answer may be no, but I am trying to store the old value from a text field in a custom property when a new value is entered. I’m doing this through a propertychange script:

value = event.source.value.oldValue

event.source.OldVal = value

However, this is causing me to get the error:

Does the numeric text field not have an oldValue attribute, or do I just completely have my code messed up?

Is that the extent of your code in the propertyChange event? If so, then you need to filter it down to just property changes on the text property; something like:

if event.propertyName == "text":
    event.source.OldVal = event.oldValue

You nailed it on the head! In hindsight that completely makes sense that it wouldn’t know which value changed unless I specifically told it. Revised code is:

if event.propertyName == "floatValue":
    event.source.OldVal = event.oldValue
