We are running the newest version of the js prototype library 1.5.1.1 and discovered a possible bug; the bug is also present in 1.6 RC1.
We have pages that embeds a flash map, via ESRI arcExplorer. Whenever you navigate to a page with the flash map, and then navigate away from the page the following JS error is thrown: (Seems To Occur On the pageUnload())
Line: 2759
Error: ‘Prototype.BrowserFeatures.XPath’ is null or not an object
It belongs to this block of code:
compileMatcher: function() {
// Selectors with namespaced attributes can't use the XPath version
if (Prototype.BrowserFeatures.XPath && !(/\[[\w-]*?:/).test(this.expression))
Thanks for the assistance.
