last function in calculated item does not allow "hostname":"item" syntax?

[just4fun]

Hi,

for monitoring my vSphere server I'm using the "extended" VMware-templates
that I found at: https://github.com/higebu/zabbix-template-vmware.

There is one item defined as calculated item and the formula is:

last("vmware.vm.hv.name[{$URL},{HOST.HOST}]":"vmware.hv.hw.cpu.freq[{$URL},\"vmware.vm.hv.name[{$URL},{HOST.HOST}]\"]") * last("vmware.vm.cpu.num[{$URL},{HOST.HOST}]")

When using the templates everything is fine except this special calculated item,
it's going to be "non supported" and the message is:

Invalid first parameter in function [last("vmware.vm.hv.name[{$URL},{HOST.HOST}]":"vmware.hv.hw.cpu.freq[{$URL},\"vmware.vm.hv.name[{$URL},{HOST.HOST}]\"]")]

Could it be that Zabbix 2.4.2 does not allow the "host":"item" syntax in function
last when calculating items?
