@TroyP - it's true that some JS libraries and newer features (thinking of Promises) will do type-based argument checks like you seem to be expecting, which allows developers to omit (preceding) optional arguments completely but still pass a callback.   utag.view()  doesn't do that - if you want to omit the first argument but send the second, you need to put a falsey placeholder in for the first:   utag.view(null, function callback(){console.log("Callback fired");});   That same principle also holds true for other utag functions with optional arguments, to the best of my knowledge. Hope that helps? Best, Caleb       ... View more

Hi @Krasner, I couldn't find a possibility to attach a file, so I hope copy/paste to the forum preserves the file.

Hi @ahrasch   From how you have described this, I think your best bet is to use an extension to help you out. What you would need to do is have a variable, say utag.data.current_page_type = b.page_type and utag.data.current_page_id = b.page_id , which you update when the view happens. Then when you call a utag.link() call, you can then retrieve the data store in these data sources, put them into their respective data sources b.page_type = utag.data.current_page_type and b.page_id = utag.data.current_page_id  and map accordingly, when you need to set them.   Adrian    Remember to give me a kudo if you like my post! Accepting my post as a solution is even better! ... View more

The 300k limitation no longer exists as it has been resolved. There is no max limit per profile.  ... View more

To follow up on this issue:   The assumption that several visitor profiles were merged was indeed correct. The reason for this is the md5 hash of the userID (through the Tealium iQ Crypto Extension) invalidates the check in AudienceStream that the value exists. Meaning the extension sets this to the hash of an empty string, in this case (d41…27e), which means the "is assigned" or "is not empty" logic would be met. We are seeing the hashed empty string as the secondary_id in the visitor profile.   The Crpyto Extension does not currently allow a condition to be applied, so the fix is to add a condition to the Visitor ID rule in AS that the data source variable does not equal "d41…27e". ...
