list of predefined elements regex

Hello,

at the moment I'm working on a workflow that provides a virtual machine, either from scratch or from template.

I want to do a selection of all templates (virtual machines) that contains "_Template".

I created a input parameter as a list of predefined elements using the action "GetAllVM'sMatchingRegexp"

So that is how it looks at the moment:

GetAction("com.vmware.library.vc.vm","getAllVMsMatchingRegexp").call( "(.*Template/ig)" )

But no results are shown. Maybe some can help me out with that?

Thanks and regards,

weda
