v15 – IsDerived property change from t_objectproperties to t_xref?

[Paolo F Cantoni]

Our shape scripts are set up to use the IsDerived Tag (set by the derived property in the Association)

Code: [Select]

if (HasTag("IsDerived","True"))
{
setpencolor(160,160,160); //Adjust to specific needs (if required)
}
else
{
setpencolor(getUserBorderColor());
}
We've just noticed that they no longer work in v15.  Doing some ferreting revealed that setting the Derived property in the Connector pane in the Properties window sets a value in t_xref, not in t_objectproperties.  Does anyone know when this changed?  Where was it documented?  (NOTE: we've generally set the ISderived property automagically, so we may not have been directly affected by the change)

How do we access this new configuration from the shapescript?
