You can bypass doSetProperty by using setProperty directly on the object
whose properties you want to modify. Remember that doSetProperty is a
method of the tool object which takes an argument that is the identifier
of the component whose properties you are changing. This would be like:
status = oTool->doSetProperty(id, 'COLOR', [255, 0, 0])
If you want to use setProperty directly, then use getByIdentifier method
of the tool like:
oComponent = otool->getByIdentifier(id)
oComponent->setProperty, COLOR=[255, 0, 0]
to get the object reference of the component. This bypasses the
undo/redo system.
