Usually, Webtrends works like this: When a pageview happens, several Parameters are set, e.g. Page Title, Page Category or whatever Custom Parameter you set.
When, on the same page after the pageview, you fire an Event, usually all the Parameters set upon Pageview are automatically sent again with the event. So for example:
1. Pageview Request: Parameter "DCSext.pagelanguage" is set to "English" and sent to WT with the Pageview Request
2. Then, a click on a "more" link fires an Event (dcsMultiTrack) with the additional Parameter "DCSext.eventcategory = "more link clicked".
Automatically, the DCSext.pagelanguage parameter is sent with this request as well.
In Tealium though, it seems as if I have to set ALL parameters I need with every utag.link call again. In the above example, the utag.link call would only send the DCSext.eventcategory parameter, but not the DCSext.pagelanguage parameter.
That creates quite an overhead. So am I missing something? Or what is the best way to accomplish Parameters from the Pageview to persist across Event Calls?
Ok, I found out that I have to set "Preserver" in the WT Tag settings to "false". A bit misleading, I would expect that "Preserve" means that the initial values are kept for any later utag.link calls, but it is the other way round.
