Nice one, thanks
OK, yes I see - similar issue for retrieving Business Groups.
We are using plugin version 220.127.116.112325. Unable to upgrade the plugin to 6.2.2 currently in this environment. Will need to go and test it out elsewhere to see if the same fix has filtered through in that version to MachinePrefixes.
Just tested this with the 6.2.2 plugin. I've got over 200 machine prefixes in vRA at the moment and it still returns 25
var vCACCAFEMachinePrefixArray = new Array();
var vCACCAFEMachinePrefixArray = vCACCAFEEntitiesFinder.getMachinePrefixes(vCACCAFEHost);
System.log("MachinePrefix return count: " + vCACCAFEMachinePrefixArray.length);
[2015-10-06 17:11:23.264] [I] MachinePrefix return count: 25
It does work with the gist above though, so you shouldn't really need to worry about looping through each one as findMachinePrefixes does that for you :-)
