How do you set disabled/readonly attributes from a snippet?

[Jim Barrows]

I found this answer on nabble but it's regarding setting the values client side.  I want to set them in the snippet, depending on data.
This doesn't work, but will give you a better idea of what I'm trying to do:
 def bindPerson(xhtml: NodeSeq, action: () => Unit, submitButtonName: String, disableAll: boolean): NodeSeq = {
    // Hold a val here so that the "id" closure holds it when we re-enter this method
    val currentId = person.id
    val disableString :String = disableAll match {
      case true => "disabled"
      case false => ""
    }
    bind("person", xhtml,
      "id" -> SHtml.hidden(() => person.id = currentId),
      //      "version" -> SHtml.hidden(() => person.version),
      "firstName" -> SHtml.text(person.firstName, person.firstName = _, "id" -> "firstName", "disabled" -> disableString),
      "middleName" -> SHtml.text(person.middleName, person.middleName = _, "id" -> "middleName", "disabled" -> disableString),
      "lastName" -> SHtml.text(person.lastName, person.lastName = _, "id" -> "lastName", "disabled" -> disableString),
      "submit" -> SHtml.submit(?(submitButtonName), action))
  }

Use None (Option) or Empty (Box) as the value of the attribute -- this  
will cause the pairToUnprefixed implicit that is being used inside  
SHtml to not generate an attribute.

e.g.:

val disableAttr: Box[String] = if (disableAll) Full("disabled") else  
Empty

bind("person", xhtml,
      ...
      "firstName" -> SHtml.text(person.firstName, person.firstName =  
_, "id" -> "firstName", "disabled" -> disableAttr),
      ...)

I'm importing HttpHelpers, and the implicit is not there.
Did this change for M7?

I think what you want is:

"firstName" -> (SHtml.text(person.firstName, person.firstName = _) % ("id" -> "firstName") % ("disabled" -> disabledAttr))

Oh I didn't mean that you need to import the implicit, just that inside SHtml, the implicit called pairToUnprefixed is being called.

David's solution is correct using Box like I exampled. I didn't check the type signature for SHtml.text, so didn't realize it only took (String, String), not (String, Any) like pairToUnprefixed that it's calling under the covers does -- my apologies :-/
