Internet Explorer reserved word problem
Added on: Wednesday 25th February 2009
I am always hopeful that one day there will be a time that you can create a web application knowing that it will look and operate exactly the same across all browsers without the need for extensive testing in each one.
Unfortunately this won't happen soon so for the time being we are stuck with applying fixes for the various shortcomings and vagaries of modern browsers.
The problem appears to be that I had an element on the page that I had given an id of 'tags' (because I was updating the tags field for a record via AJAX).
Simply changing the id of this element to something other than 'tags' solved the problem, so it seems that this is probably a reserved word for IE.
