Just to clarify, currently a pageview event is getting triggered on the page (utag.view equivalent), but you would like to have an extension to trigger the view event into a link event for SiteCatalyst? Is that correct? Also, can you verify what version of the SiteCatalyst tag you are currently using?
Without a little more information into what exactly you're trying to do, as Jared requested in the reply above, the best we can do for you at this point is to encourage you to reach out to your Tealium Account Manager.
What I'm looking for, in general terms, is to be able to create a condition within an extension based on whether the hit is a "page view" (using s.t) or a "link click" (using s.tl). Is this possible in Tealium?
To check whether utag.view (page view event) or utag.link (link event) you can create a Set Data Values Extension like the following:
Create a new Data Source Called: _utag_event
Set: _utag_event To: JS Code -> Type in "a" (no Quotes)
Leave the scope of this extension set to All Tags
I would drag this extension to the top of the list of extensions to make sure the Data Source is available to all other extensions as needed.
See below screenshot for a visualization of how to set this up.
The new Data Source called "_utag_event" will not contain either "view" or "link" and can be used in conditions of later extensions.
Hope this helps.
