Extra command parameter (green) boxes added upon edit

When you click on the Green command parameter box and make a modification, a duplicate green parameter box shows up.

Hi Sanjay, could you please provide more details? Which command are you editing when you got this error?

Here are steps to reproduce:

  1. Select carrier_code_full
  2. Edit the filter step by clicking on the last green box where it says “!is.na(code)”
  3. Change the value from “is not NA” to “is NA”

You will see an extra green parameter box

Hi Sanjay, Thank you for the steps.

I tried the same with version 3.4.1 and if I changed the filter operator from “is not NA” to “is NA” on the last green box and click run, I still see two green boxes. Do you happen to see any error in the log file?

I restarted Exploratory and was not able to reproduce it. I checked the log and there were some errors but I don’t recall what I was doing when it happened:

Mon May 01 2017 14:47:42 GMT-0400 (EDT)] ERROR { '0': 
   TypeError: Cannot read property 'length' of null
       at Function.a.toTransformUserFriendlyMessage (

I will reply back if it happens again and try to note what I did differently.
