Attempting to start NodeManager with WLST

Question

I have a WLST script that list all the configured nodemangers in a domain. I use that list to make a menu. In theory I am trying to have a user pick a nodemanager from the menu and start it without providing any other information. It's not working out well. Here is what I am doing:
#Create Menu
def display():
nm = cmo.getMachines()
menuItems = {}
num = 1
for nodeName in nm:
print "%d. %-3s" % (num, nodeName.getName())
menuItems[num] = nodeName.getName()
num = num + 1
try:
selection = raw_input("Make a Selection: ")
print ""
print "You selected %s" % menuItems[int(selection)]
choice = menuItems[int(selection)]
return choice
except KeyError, ValueError:
print "%s is not a menu option!" %
I make the following call: pick = display()
This stores the nodemanager name in var pick to use later.
I then run the following method: StartNodeManager(pick)
The contents of the method:
StartNodeManager(pick)
serverRuntime()
WLHome=cmo.getWeblogicHome()
NODEManagerHome=WLHome+'/common/nodemanager'
domainConfig()
cd('/Machines/' pick '/NodeManager/' +pick)
nodeIP = cmo.getListenAddress()
nodePort = cmo.getListenPort()
startNodeManager(verbose='true', NodeManagerHome=NODEManagerHome, ListenPort=nodePort, ListenAddress=nodeIP)
When 'startNodeManager(verbose='true', NodeManagerHome=NODEManagerHome, ListenPort=nodePort, ListenAddress=nodeIP)' command is run I get the following error:
Problem invoking WLST - Traceback (innermost last):
File "/home/beaadmin/bin/scripts/wlst/nodemanager-v103.py", line 123, in ?

File "<iostream>", line 1589, in startNodeManager
TypeError: setProperty(): 2nd arg can't be coerced to String
Is that saying the NodeManagerHome value is throwing the exception? When I set all the vars manually in WLST and run the startNodeManager command it runs fine.
Any ideas?
The code for the StartNodeManager method is as follows:

I looked that up and tried running it a couple of different ways and got the following:
os.spawnlp(os.P_WAIT, startNodeManager(verbose='true', NodeManagerHome=NODEManagerHome, ListenPort=nodePortS, ListenAddress=nodeIP))
Problem invoking WLST - Traceback (innermost last):
File "/home/beaadmin/bin/scripts/wlst/nodemanager-v103.py", line 141, in ?
File "/home/beaadmin/bin/scripts/wlst/nodemanager-v103.py", line 120, in StartNodeManager
AttributeError: class 'org.python.modules.os' has no attribute 'P_WAIT'
os.spawnlp(startNodeManager(verbose='true', NodeManagerHome=NODEManagerHome, ListenPort=nodePortS, ListenAddress=nodeIP))
Successfully launched the Node Manager.
The Node Manager process is running independent of the WLST process.
Exiting WLST will not stop the Node Manager process. Please refer
to the Node Manager logs for more information.
The Node Manager logs will be under /dsto/sw/dev/bea/WEBLOGIC.11.1/oracle11g/wlserver_10.3/common/nodemanager
