Play Framework 2.0 template engine define writabel variables

I'm using the play framework template engine based on scala. The controller are written in Java.

Is there a way to define a inline writable variable?

I just found this at the documentation:

@defining(user.getFirstName() + " " + user.getLastName()) {
    <div>Hello @fullName</div>
}

But this only create a readonly variable.

Edit: I am using a loop in my html page:

@for(variable <- variables) {

This kind of a loop dosen't give me a index variable. I need this index to give different outputs for the first loop and all others. Hope this is clear?

So I just thought I could create a index variable outside the loop and increment it on each loop.

Has anyone an idea? Thanks

Try:

@for(for(i <- 0 to list.size-1) {
   @list(i)
}

or simply:

@for(i <- list.indices) {
    @list(i)
}

I think zipWithIndex is what you need:

@variables.zipWithIndex.map { case (variable,index) => <h1>@variable</h1>}
