Just a guess (I haven't looked at any plugin or GA code):
In order to track the viewing of individual tiddlers, I assume that
the TW implementation for Google Analytics (GA) is hijacking the
core's displayTiddler() function. I also assume that this hijack
takes the tiddler title, as passed to displayTiddler(), and uses it to
construct a 'fake' URL with "/TiddlerName" on the end of it that is
reported back to GA.
However, the displayTiddler() function can accept either a tiddler
*title* (a text string) or a tiddler *object* (which it then accesses
to get the title). As a result, if the GA-hijacked displayTiddler()
code attempts to use the tiddler *object* in a text expression to
construct the fake URL then, because the tiddler object does not have
a .toString() method, it reports back "[object object]" instead of the
actual tiddler title.
Here's the first few lines of the core's displayTiddler() javascript
code that illustrates the technique for properly accessing the title:
-----------------------
Story.prototype.displayTiddler = function
(srcElement,tiddler,template,animate,unused,customFields,toggle,animationSrc)
{
var title = (tiddler instanceof Tiddler) ? tiddler.title : tiddler;
-----------------------
If this code technique is applied to the appropriate place in the
current GA-hijacked code, it should eliminate the spurious "[object
object]" from items appearing in your logs.
Another approach that might work, but has potentially more far-
reaching effect, would be to add a .toString() method for the tiddler
object:
-------------------
Tiddler.prototype.toString() = function() { return this.title; }
-------------------
Once this is defined, use of a tiddler object within a text expression
should trigger the .toString() method, resulting in the actual tiddler
title being used in the expression instead of "[object object]".
enjoy,
