Subject:	RE: zenoss 6.2.1 - zendmd - running commands on datasource templates failing

the issue seems to be that a None Type Datasource is returned by the get_datasource method, for example in zendmd when i run the below code you can see this:


t = dmd.Template.create("MyTemplate", "/zport/dmd/Devices")

# In [18]: t.add_datasource("DsCheckLoad")
Out[18]: <ZenPacks.TNF.QualityMonitor.util.dmd.objects.Template at 0xdf21e90>

# ds = t.get_datasource("DsCheckLoad")

# [20]: ds

#In [21]: type(ds)
Out[21]: NoneType

# In [30]: t.get_datasources()
Out[30]: []


In zenoss 5 this used to return a datasource object type.
Does anybody know what has changed here in zenoss6 with zendmd?

However with zenoss 6.2.1 I can no longer do this, and errors are thrown stating I cannot run the various commands on the datasource template.
​Has anybody else come across this issue with zenoss 6.2.1 and have any idea of how to overcome it?
