Occurrence Attributes in CommandInputChangedHandler

[Anonymous]

The code below changes the occurrence attribute when called from the CommandCreatedHandler, but when I call this function in the CommandInputChangedHandler, it clears the selection input and does not permenantly change the occurrence attribute. Any help would be appreciated, as I am just beginning. def addOccurrenceAttribute(occurenceName, value): try: product = _app.activeProduct design = adsk.fusion.Design.cast(product) design.rootComponent.allOccurrences.itemByName(occurenceName).attributes.add("group","name",value) except: _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Hello,

The model changes made in InputChanged event handler would be rolled back because they are intermediate. I would recommend to do that in CommandExecuteEvent handler, which is best practice.

Thanks,
