How to invalidate solution when updating ACT load object property via script? If I update the property of the load object via GUI, it invalidates the solution, but the same update via Script doesn't invalidate the solution.
Please try changing in the xml by adding propertevents tag for Interface, as shown below.
propertevents can be set to: "all" = "ui" + "script" -> property will be updated when script or ui changes are invoked. "ui" -> only UI updates allow for properties in the UI to be updated.
<interface context="Mechanical" propertyevents="All">
