> The fix for TAP5-1147 causes an exception when it finds an element with a
> function for an attribute value under IE 8. In the purge function in
> tapestry.js starting at line 640, the count of attributes is kept in a
> variable, then the attributes are processed starting at the beginning. When
> an attribute is found where the value is a function, the attribute is removed
> and the count of attributes changes. When the loop gets to the end, an
> exception is thrown because attrs[i] is undefined.
