I've created a regular expression for AHR to identify hostnames from switch alias that seemed to work...or at least this is what it let you believe.
In switch alias I have Adapter_A_rm_hostname or Adapter_B_rm_hostname and I've created Adapter_(.*) as regular expression. In preview I can see red underlined the correct path that will be extracted (A_rm_hostname or B_rm_hostname, customer want both). Format is \1.
But nothing happen and clicking on Preview button I've got 0 matches and the No Match window report "invalid character for name". Which name? Which char?
