<![CDATA[[Solved] Script / modifyObject mapgroup / NullPointerException]]>Hello,
i have a problem to change  "Status Calculation Method" on mapgroup with a script,  mapgr is a NetworkMapGroup :

        print "mapgr.getObjectClassName(): %s " % ( mapgr.getObjectClassName())
        print "mapgr.getStatusCalculationMethod(): %s " % ( mapgr.getStatusCalculationMethod())
        md = NXCObjectModificationData(mapgr.getObjectId())
        print "md.getStatusCalculationMethod() : %s" % (md.getStatusCalculationMethod())
        md.setStatusCalculationMethod(3)
        print "md.getStatusCalculationMethod() : %s" % (md.getStatusCalculationMethod())
        session.modifyObject(md)

result :

mapgr.getObjectClassName(): NetworkMapGroup
mapgr.getStatusCalculationMethod(): 1
md.getStatusCalculationMethod() : 0
md.getStatusCalculationMethod() : 3
Traceback (most recent call last):
  File "Creation-de-map_3.py", line 12, in <module>
    session.modifyObject(md)
	at org.netxms.client.NXCSession.modifyObject(NXCSession.java:4953)

Why md status calculation is different from mapgr status calculation  ?

Any ideas?
Thanks

that's an inconsistency in API - you should set all status calculation and propagation properties when modifying any of them. So in your case you have to call on md object: setStatusPropagationMethod, setFixedPropagatedStatus, setStatusShift, setStatusTransformation, setStatusSingleThreshold, setStatusThresholds. You can just pass values from appropriate getters on mdgr object.

Best regards,
Victor
