I'm using VFP 7.0
I have a hidden property that disappears before the Destroy() method during runtime.

Define class myClass ...
  hidden oControl_Next

  Procedure Destroy()
    this.oControl_Next = .null.        << "property oControl_Next not found" in runtime
EndDefine

class works fine during development, just in runtime it crashes.

If I change the property to protected, then it works in runtime also.

I've verified that the property is not used anywhere in any subclasses.

TIA
