Hi, I have a scripted field returning a number "x" based on some calculation using Painless language, now I want to use that same number "x" in a new scripted field running expression language:  
`(doc['something'].value / doc['x'].value) *100`

But it's throwing an exception:  
`"type":"parse_exception","reason":"Field [x] does not exist in mappings"}}`

Now the exception is obvious as the field "x" is a scripted field and not a doc field so is there any solution to reuse my "x" variable somehow using expression lang?
