default value
                 Key: ZEPPELIN-669

Steps to Reproduce:
--
1. run the code:
{code:java}
val selected = z.select("", List(("a", "a"), ("b", "b")))
println(selected)
{code}
output is "", which is expected. "a" is selected in UI, which is not expected?

2. select "a": output is "". BUG: should be "a"
3. select "a": output is still "". This will be forever if I don't select "b"
4. select "b": output is "b"
5. select "a": output is "a"
