<![CDATA[java.lang.String cannot be cast to org.netxms.client.objects.configs.CustomAttri]]>Hello,

I updated my netxms and nxshell version (2.2.15 => 3.1)

An attribute creation script doesn't work anymore.
Can you help it?

import csv, sys
from java.util import HashMap
...
...
        MAT = s.findObjectByName(MATname)
        if MAT :
            MATId = MAT.getObjectId()
            md = NXCObjectModificationData(MATId)
            MODIF = HashMap()
            MODIF.put("UR1location", Location)
            md.setCustomAttributes(MODIF)
            session.modifyObject(md)
            w.writerow([
                MAT.getObjectId(),
                MAT.getObjectName(),
                MAT.getCustomAttributes(),
                ])

I'm getting the next error:

Traceback (most recent call last):
  File "/data/infra/scripts/NetXMS/Custom-Attributes_UR1location.py", line 27, in <module>
    session.modifyObject(md)

The "Snmp Location KO" card just didn't exist.
After create it, it's ok.

Many thanks.

Best regards,

Try to check return value for None before using it for getObjectId.

Best regards,

Thank a lot.

I have other problems when creating maps...

Seed = s.findObjectByName("NameOfMySeed")
SeedId = Seed.getObjectId()

NetworkMaps = s.findObjectByName("Network Maps")
NetworkMapsId = NetworkMaps.getObjectId()

SnmpLocationKO = s.findObjectByName("Snmp Location KO")
SnmpLocationKOId = SnmpLocationKO.getObjectId()

I have this error:

Traceback (most recent call last):
  File "/data/infra/scripts/NetXMS/Creation-de-map_ALL.py", line 27, in <module>
    SnmpLocationKOId = SnmpLocationKO.getObjectId()
AttributeError: 'NoneType' object has no attribute 'getObjectId'

Can you help me again?

Thank you
BB

setCustomAttributes methos now expects Map<String, CustomAttribute> instead of Map<String, String>. Try to replace line

MODIF.put("UR1location", Location)

with

MODIF.put("UR1location", CustomAttribute(Location, 0, 0))

Best regards,
Victor
