[rt-users] Using "__CurrentUser__" in a Custom Field "LinkValuesTo"

[David]

Hi,

I am trying to create a custom field that will contain a link with
something like:
http://host/script.pl?variable1=__CurrentUser__&variable2=__id__

This perl script will in return use RT::Client::REST to do far more
complicated tasks with the data passed to it.

Now, while __id__ works, I'd like the field to also use
__CurrentUser__ (as a search would do).

Is this possible ? I've looked through the documentation, google and
mailing lists but to no avail.

Thanks,

- David
