Apache Zeppelin - error: overloaded method value run with alternatives - angularjs

Question

I am trying to use the angular binding feature available in Apache Zeppelin in the following code:
val ab10 = z.sqlContext.sql("select "+ z.angular("selectVari0") + " from MyDF")
ab10.toDF.registerTempTable("ab0")
z.angularBind("abb0", ab10)
val selvar = z.getInterpreterContext()
z.angularUnwatch("abb0")
z.angularWatch("abb0", (before:Object, after:Object) => {
z.run(15, selvar)
})
I get the following error:
ab10: org.apache.spark.sql.DataFrame = [BMI: double]
warning: there was one deprecation warning; re-run with -deprecation for details
selvar: org.apache.zeppelin.interpreter.InterpreterContext = org.apache.zeppelin.interpreter.InterpreterContext#216b8218
<console>:31: error: overloaded method value run with alternatives:
(x$1: java.util.List[Object],x$2: org.apache.zeppelin.interpreter.InterpreterContext)Unit <and>
(x$1: String,x$2: String)Unit
cannot be applied to (Int, org.apache.zeppelin.interpreter.InterpreterContext)
z.run(15, selvar)
^
I tried anther example from here. I got similar errors. I was not able to find any documentation to fix this error.

As stated in error message, you have to overloaded .run methods, with following signatures:
(x$1: java.util.List[Object],x$2: org.apache.zeppelin.interpreter.InterpreterContext)Unit <and>
(x$1: String,x$2: String)Unit
Please, try to call it like this:
import collection.JavaConverters._
z.run(List(15).asJava, selvar)
