SDK 1.5 invoke with Perl ?

Hello,

I am just studying the New SDK 1.5 with the examples. I was able to read a node Information and to add a Node with severall properties with the perl client but I am unable to do a invoke operation with perl . Unfortunately there isn't any invoke example in the sample.pl although invoke is defined in the perl module.

I want to add a Node to the NCM. I got the ID from the node but I was unable to add him with perl.

I tried

print $swis->Invoke('Cirrus.Nodes', 'AddNodeToNCM 1485');

What would be the correct syntax for that operation ?

Best regards
