Yes, I'm running against nightly build of 2.5.1 (2.5.1-SNAPSHOT from sonatype).

 

The error in this thread isn't EL's fault, but a result of how Scala encodes primitive types passed as type-parameters to Option. Option[Int] gets the byte-code signature Option[java.lang.Object] and not Option[java.lang.Integer] as one might think. Therefore it's impossible for EL to distinguish between Option[Int] and Option[Long] which results in this error. Option[DateTime] and Option[String] work fine as they are reference-types.

 

I consider this issue closed.
