SetValue callback of property not calling function

Question

Hi all, I'm working with ANSYS 2025R2, I'm new in developing, sorry if I ask a silly question. I'm extending the VMStresses example from Ansys. Till now, I added three properties. I want to run a function after the values (of the first two properties) have been set or changed. But the TestCallback function gets not started. Why? I included a log message in the TestCallback function. Thanks for your feedback. 3bd77033-f9b4-4970-b427-ef4c77e8cc60

@aquavia You are correct that OnValidate is the callback you are looking for.  This is the callback that is used to validate (or not) the data that has finally been used.  There is a bit of internal steps that is done when values are input and there is a getvalue, value2string, and setvalue callbacks.  These are used to take in the value, and potentially modify it or represent it.  Best example of this is an object selection.  The value that is used is the unique object id, but you want to represent that as the object name.  There are other purposes, but the bottom line is YES: use the OnValidate callback for the kind of action that you want to run code each time a user changes a property input.

I still dont understand why SetValue does not work, but OnValidate works.
