    Simple throw an error inside your onAfterAdd/Update/Version Method. This way you can also give your users some feedback about what they did wrong.

    e.g.

    Innovator inn = this.getInnovator();
    var myprop = this.getProperty("name","");
    if (myprop != "sampleValue")
    {
       return inn.newError("Cannot save item, name is wrong");
    }

    The newError will prevent that your new or updated item will be saved.

hello,

i think i need an intelligent checking because i want to implement a multi field logic  .

a simple approach of my problem would be, two fields on an item creation form and if one of them is filled in the other one should be too and if its not the case the user should not be able to create the item and should be able to modify the invalids inputs .

but the thing i don't understand is how to disallow the creation of the part if the logic i implement gives a "false" output (when one field is filled in and the other isn't) or basically how to replicate the "required" behaviour through code

thanks,

Lucas.
