Hey, I have a problem with the validation error messages. It happens when the email already exists but it shows a message a saying the user name already exists. I traced the workflow and found that the error was propagated when the System.Account object is created. I suspect that the problem is due to mendix having its own validation inside its account system. And to solve it I need to override the default message. Is my chain of thougth correct and if so can I override the validation message. Any help is appericiated. Thanks
If you want to change the message “Username is already existing” than you can go to Language, Batch replace… and from there find the text and change it.
But your best option is to create your own validation before you create a new user or account to make sure that what you are using as accountname is not already existing.
