#1 Updated by Matthew Jones about 11 years ago

Trying to switch the CN environment from the R client causes the error:

Error: The provided mnNodeid value is invalid for the DataONE environment

When one first opens R, running this succeeds:

@mn_nodeid <- "urn:node:mnDemo5" # MN for DEV env
cli <- D1Client("DEV", mn_nodeid)@

But then, if one tries to switch environments, the error above surfaces:

@ mn_nodeid <- "urn:node:mnSandboxUCSB1
cli <- D1Client("SANDBOX", mn_nodeid)@

The problem seems to be because R loads Java classes statically via a JNI interface, so I'm thinking that the library is caching the old environment and therefore not seeing the the MN you request. There's no way in R to cause the Java library to reload. I can consistently change environments as long as I restart R in between trying to switch environments with the D1Client.
