User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)

using an observes tag in xbl definition of a new widget to monitor curpos attribute in scrollbox. If the observes tag is ABOVE the scrollbox, an onbroadcast event is triggered. If BELOW, onbroadcast is NOT triggered. Strange!!!

Simulating the same XUL directly in an XUL file, with not XBL, did not cause the error.

problem.xul problem.css and problem.xml attached to demonstrate XBL behavior. 

Reproducible: Always

Steps to Reproduce:
1.load problem.xul file attached to this report
2.move the upper scrollbar
3.move the lower scrollbar
Actual Results:  
1. When upper scrollbar is moved, and alert is shown
2. When lower scrollbar is moved, no alert is shown

Expected Results:  
an alert should have been triggered in both cases

slight error in "expected results" of original report: Upper scrollbar does NOT trigger alert. Lower scrollbar DOES trigger alert.

Other that the placing of the scrollbar and the scrollbox within the xbl definition, and naming them slightly differently, there is absolutely no difference between the code.
