I was asked to prevent a user from submitting a XaaS request form, if the user entered invalid input in one of the fields.
Lets say for an example, that I want create a XaaS blueprint that validates JSON files. One of the fields would be a text area where the
user can paste in the content of the JSON.
Now, I know I can add another control that invokes a vRO action to validate the field, but is it possible to prevent the user from submitting the form if
the JSON is invalid?
