miss changelist number in email-ext plug-in with Perforce

[michael chiu]

Hi ALL, 
           Have anyone use email-ext groovy template to display Perforce 
changeset info ? 
           I found it missed "changelist number " or is it a bug  in the 
groovy-html.template.
           It seem ${spc} don't work. what's the ${spc} mean ? 
           I'm using the lastest email-ext plugins and perforce plugin in 
Jenkins 1.465 ?

Regards,
Michael Chiu
