Specify a default expression for a Measurement in the definition.xml for an extension?

pvintona8 — Mon, 26 Jan 2026 16:26:21 GMT

Is there a way to specify a default expression for a Measurement in the definition.xml for an extension? I'm looking for somthing similar to the Expression attribute that is available for Text objects:

I've tried to "push" a value into the expression via script.js and properties.qvpp, but can't get those methods to work either. If somebody can help figure out this methodology instead, that would definitely be an acceptable solution too.

Thanks for the help!

Erik, any idea why I would get a "Server Error" whenever the Value attribute contains a ">" character? Every other special character I use seems to work without a problem. Any ideas for a workaround?

You must escape some characters in xml:

" " ' ' < < > > & &
