[rt-users] How to access a CustomField from Ticket/Tabs

[Brumm, Torsten / Kuehne + Nagel / Ham MI-ID]

Hi RT Gurus,
is there any way to access the content of a CustomField from Ticket/Elements/Tabs ?

I try to create a new button called "Reinstate" which will set back the status to last know status (stored in a CF).

Something like this:

$actions->{'AC'} = { path => "Ticket/Display.html?Status={CustomFieldValue('OldStat')}&id=" . $id,
                     title => loc('Reinstate') };

Not sure if this is possible.

Any ideas or solutions as workaround?

Greetings

Torsten
