Retrieving the Tag ID through REST

Hi guys,

I appear to be in bit of a bind. Currently I'm modifying the Tag View Page to use a customized thread list appearance but I need to create 'View All' link for sections 'Recently Tagged' and 'Most Tagged', however the link requires the tag ID to be passed as a parameter to the Tag Detail Page if I want to get the full list of Recently Tagged or Mostly Tagged threads.

So here is how I grab the tag element from the Tag View Page

<#assign tag = webuisupport.path.parameters.name.get("tag-id")/>

If I print out the tag value on to a page, it would look like this:

StandardTextTag[tagText=Clienterror,id=TextTagByUidRef[uid=15,hashCode=1737709434],canonicalDisplayRef=TextTagByTextRef[tagText=Clienterror]]

So if I use ${tag.tagText} I get "Clienterror" but how do I go about getting the ID of the tag I'm viewing in that page? Both ${tag.id} and  ${tag.id.uid} node return with "Expression is undefined" errors, after searching through the documentation I haven't come across any way of getting this node value

Thanks!
