SimpleForm Exception

[T00mm]

When trying to create your own SimpleForm, when using the edit function you will get an [IllegalArgumentException: argument type mismatch] error. The new object function works.

The error-log

Please check out the argument types in your template code. You should provide right key and form types in the template as in this sample.

[T00mm]

Yes, I am using

@(key: Long, simpleForm: Form[Voeding])

and Voeding is a model

It also only happens when I go to the edit page, the create page works fine.

Please turn DEBUG logging for "play.utils.crud" package on and paste detailed logs here.

I think I have noticed the error

[debug] p.u.c.CRUDController - model : Simple [key=1, name=qsddqs] 

But I am not sure how I could fix this?

[hakandilek]

:) Search for "Simple" in your code and replace with "Voeding". It's probably in your Controller class but may be more.

[T00mm]

Yeah my controller class is just

package controllers;

import play.mvc.Controller;
import play.mvc.Result;
import play.api.i18n.*;

public class Application extends Controller {

    public static Result index() {
        return ok(views.html.index.render());
    }
    public static Result changeLanguage(String langCode) {
        changeLang(langCode);
        return ok(views.html.index.render());
    }

}

routes is just

# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

# Home page
# Home page
GET     /               controllers.Application.index()
GET     /language       controllers.Application.changeLanguage(lang ?= "en")
# CRUD Controllers
->     /app             play.crud.Routes
# REST API
->     /api             play.rest.Routes

#Assets
GET     /assets/*file   controllers.Assets.at(path="/public", file)

For the rest, I can't find Simple anywhere.

[hakandilek]

Any other occurences of "Simple"? What about DAOs?

[T00mm]

I don't think I have ever defined a DAO, also I have just refreshed and now I just get

As you can see

[debug] p.u.c.CRUDController - model : Voeding [key=1, name=qsddqs]

is now reporting the correct model

Can you please fork the project and add your problem sample as a separate sample project under samples folder so I can have a closer look.
