How to validate with "warning" instead of "error" using formValidation plugin?

I'm using the formValidation plugin located here to perform input validation check on a HTML5 form. The error validation works fine but now I have a case where I need to provide a warning instead of an error on an input validation, where the user can still proceed with a submit if invalid.

I've done a quick search on the topic but didn't find anything worthwhile which is why I'm posting here for advice.

Question:

How can I validate with a warning using the formValidation plugin?

HTML input -

  <input id="ApplicationID" name="Application"  required="required" type="text" class="form-control">

Code -

     //Validate the required input fields to prevent submit if not 
    //populated.
    $('#createForm').formValidation({
        framework: 'bootstrap',
        icon: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {

            Application: {
                validators: {
                    notEmpty: {
                        message: 'The idVal name field is required'
                    },
                    callback: {
                        message: 'A record for this Application type already exists!',
                        callback: function (value, validator, $field) {
                            // Determine if the input idVal already exists
                            var idVal = $('#ApplicationID').val();

                            //Check that idVal isn't empty before calling match validation
                            if(idVal )
                            {
                                //Call a bool method to check if idVal already exists
                                return checkEPRIDExists(idVal );
                            }

                        }

                     }
                }
            }

        }


    });

The current validation prevents submit and highlights red, looking for an amber warning instead that allows submit if invalid:

Not sure how you ended up going with this one since it was a while ago.

Here's an example which details how to implement a Warning for a field (instead of just an error or success).

I think the key thing is that you've got to add the events to trigger on either success or error within formValidation.

$('#createForm').formValidation({
   framework: 'bootstrap',
   icon: {
       valid: 'glyphicon glyphicon-ok',
       invalid: 'glyphicon glyphicon-remove',
       validating: 'glyphicon glyphicon-refresh'
   },
   fields: {
       Application: {
           validators: {
               notEmpty: {
                   message: 'The idVal name field is required'
               },
               callback: {
                   message: 'A record for this Application type already exists!',
                   callback: function (value, validator, $field) {
                       // Determine if the input idVal already exists
                       var idVal = $('#ApplicationID').val();

                       //Check that idVal isn't empty before calling match validation
                       if(idVal )
                       {
                           //Call a bool method to check if idVal already exists
                           return checkEPRIDExists(idVal );
                       }

                   }

                }
           }
       }

   }
 })
 // This event will be triggered when the field passes given validator
 .on('success.validator.fv', function(e, data) {
     // data.field     --> The field name
     // data.element   --> The field element
     // data.result    --> The result returned by the validator
     // data.validator --> The validator name

     if (data.field === 'Application'
         && data.validator === 'callback'
         && (data.fv.isValidField('Application'))){
         // The Application field passes the callback validator
         data.element                    // Get the field element
             .closest('.form-group')     // Get the field parent

             // Add has-warning class
             .removeClass('has-success')
             .addClass('has-warning')

             // Show message
             .find('small[data-fv-validator="callback"][data-fv-for="Application"]')
                 .show();
     }
 })
 // This event will be triggered when the field doesn't pass given validator
 .on('err.validator.fv', function(e, data) {
     // Removes the has-warning class when it doesn't pass any validator
     if (data.field === 'Application') {
         data.element
             .closest('.form-group')
             .removeClass('has-warning');
     }
});
