Hello,
I discovered an issue with sorttable.js - which you might want to fix in future releases.
In IE 7, when viewing any page with a sorttable class, the page returns an array error:
Error Sys.ArgumentTypeException: Object of type ‘Object’ cannot be converted to type ‘Array’
This error also disables the use of sorttable.js, and makes all the tables unsortable.
To solve the issue, find and replace any "forEach" with "AforEach", including resolve.forEach(object, block, context) in sorttable.js.
The error stems from this bug:
