actual argument play.data.Form cannot be converted to play.api.data.Form

play doesn't convert my java form object to the scala world. 

    [error] /home/myproject/split/frontend/app/controllers/frontend/Configuration.java:46: error: method render in class settings cannot be applied to given types;
    [error]             return ok(settings.render(settingsForm.fill(userSettings)));
    [error]                               ^
    [error]   required: play.api.data.Form<Settings>
    [error]   found: play.data.Form<Settings>
    [error]   reason: actual argument play.data.Form<Settings> cannot be converted to play.api.data.Form<Settings> by method invocation conversion

the view-template looks like this: 

@(settingsForm: Form[Settings])

@import play.i18n._
@import helper._
@import helper.twitterBootstrap._

@main {

    @helper.form(action = controllers.frontend.routes.Configuration.setSettings) {

Any idea?

I should also mention that we use project split main->frontend->common and main->backend->common. We moved this page (view and controller) from common to frontend. It worked in common fine. Now in frontend I get this error.

I actually had a similar problem with a java.util.List and I had to add templatesImport ++= Seq("java.util._", ... to the settings: 

  val frontend = play.Project(
      appName + "-frontend", appVersion, path = file("main/frontend")
  ).settings(
      templatesImport ++= Seq("java.util._", "models.frontend._")
  ).dependsOn(common).aggregate(common)

I tried with play.data._ already, didn't help.

Your frontend project is a Scala project, not a Java project. Add a dependency on javaCore to it, and it will be a Java project. Then do a play clean compile, and everything should work. Eg:

val frontend = play.Project(
  appName + "-frontend", appVersion, Seq(javaCore), path = file("main/frontend")
).settings(
  templatesImport ++= Seq("java.util._", "models.frontend._")
).dependsOn(common).aggregate(common)
