[alvarolm]

Bug Report

when setting the default prompt (function) for a custom rule it triggers the error:
Uncaught TypeError: prompt.search is not a function
https://github.com/fomantic/Fomantic-UI/blob/develop/src/definitions/behaviors/form.js#L564

Steps to reproduce

set this defaults before instanciating a form

$.fn.form.settings.rules.mindate = function(value) {
return false;
};

$.fn.form.settings.prompt.mindate = function(v) {
return "custom prompt working!"
}

Expected result

no error

Actual result

Uncaught TypeError: prompt.search is not a function

The custom prompt has to be provided at type declaration
https://fomantic-ui.com/behaviors/form.html#customizing-prompts

rules: [
          {
            type   : 'myrule',
            prompt : function() {
							return "custom prompt working!"
						}
          }
        ]

Your other approach works too, but only if the central value is type of string (this is something we could improve to also accept functions here)

$.fn.form.settings.prompt.myrule = "custom prompt working!";

understood, in my case the prompt is always generated so it needs to be function, for now it seems i will have to provide it each time with a type declaration

may be in the future I'll implement pr, thanks !
