[Iplant-api-dev] Questions about passing boolean variable from DE to api

[Wang, Liya]

Roger,

Thanks. I might need to explain it better.

For the current DE, if x is true, it will be passed as empty. If x is false, it will be ignored so that it will not appear in the command line in iplant.sh.

I am not sure how the API adapter is coded to handle this but none of the approaches I tried actually works.
