Object is Not a Member of Package. Note: class exists, but it has no companion object

Play Framework

Hi All,

I am getting this sbt clean compile error:

[error] /home/kenny/workspace/ace-4.0-golden/app/views/dash.scala.html:10:11: object header is not a member of package views.html.includes
[error] Note: class header exists, but it has no companion object.
[error] @includes.header("Dashboard", userId, partyId, appId)

Directory structure:

app
.... views
........ dash.scala.html
........ includes
............ header.scala.html

header.scala.html:

@import common.Configuration;
@import common.Global;
@import common.ZendeskJWT;
@import controllers.Admin;
@import models.User;
@import esavv.entities.App;
@import esavv.entities.Role;
@import esavv.entities.View;

@this(configuration: Configuration)

@(title: String, userId: String, partyId: Int, appId: Int)

@includes.header("Dashboard", userId, partyId, appId)

Google and Stack Overflow haven’t been able to help me. I was wondering if some Play experts had come across and solved this.

What is includes supposed to be?

3

A directory under views. Thanks, I should have mentioned that.

4

Header is another template then? Do you have template DI enabled perhaps?

5

Is it not simply that the template engine is interpreting

@includes.header("Dashboard", userId, partyId, appId)

as a call to includes.header.apply(...)?

7

It’s enabled by default, but I tried explicitly enabling it and get the same error.

8

If so, what should I do? I was trying to follow the play-java-starter-example on GitHub.

The starter example doesn’t have views organized in subdirectory, so I don’t get what you mean.

I’m not sure it’s related to the templates’ organization. I see that header has a constructor (@this(...)) so I guess you can’t include it anymore into other templates as a static function call (i.e. @includes.header(...,...))

I think you need to instantiate it with the constructor paramater and pass the instance to the dash template and only then call the instance with the ("Dashboard", userId, partyId, appId) arguments, just as if it was a function.

it wouldn’t make sense any other way, if you think about it:
when you do @includes.header("Dashboard", userId, partyId, appId) how could the instance of header included have been created, what will be his configuration?
