Imagine you have the following:

publicBoolean box1=false;
publicBoolean box2=false;

In this case, when the bindFromRequest() occurs and the POST method did not send any value for the field box1 and/or box2, the fields will be filled with the default (false) value.

On the view, the only thing you will need, is as follows (I don't use the play helper):

<inputtype="checkbox"
     name="@helloForm("box1").name"
     value="true"     @if(helloForm("box1").value.contains("true")){checked="checked"}> Box 1

This will check your checkbox if the field was sent to the view as true
