Hi,Can any one please post an example of how to use the "validateUnique" validation of FormControlValidationMixin.The usage is given like, { "validation": "validateUnique", "errorMessage": "Already used", "itemsProperty": "items", "publishTopic": "GET_VALUES" }
But I could not see any examples on how to use this.For example, I am adding this in a field of a form say "prefix" to validate the uniqueness, now how can I make the "GET_VALUES" topic to retrieve the list of "prefix" and put it in "items".Please let me know if you are not clear about my question.Thanks in Advance.
