I'm kinda new in the Oracle Commerce ATG technology and don't understand many of its concepts yet. By now I have encountered an issue I couldn't find any resolution to. I'm trying to update a particular property of an item in a versioned repository using the standard way through the method setPropertyValue() on a MutableRepositoryItem object and then updateItem() on the repository object itself. But it doesn't work and I get that error message. Error message
Maybe someone could enlighten me what should I do to resolve that issue?
