it is by overriding the method 'getInputName' on every FormComponent and
returning a stable identifier over requests - though this is pretty horrible
task to do.
If you're using Scala instead of Java things are getting better, though. I
defined the following trait (aka implemented interface):
---
object FormInputNameId {
private var currId = 0
private def getName = {
if( currId==Integer.MAX_VALUE-1 ) currId=1 else currId = currId + 1
"fid:" + currId
}
}
trait FormInputNameId[T] extends FormComponent[T] {
override val getInputName: String = FormInputNameId.getName
}
---
This trait can be attached to any FormComponent with just something like
val newFormComponent = new TextField( "id" ) with FormInputNameId
The Scala compiler does the rest for you (one of my favorite features of Scala
to have real reusable code!).
Best regards, --- Jan.
