Hi, >From within a call to `SectionText`'s `extension` function, you can use `$super` to call `Section`'s version, although be aware that Prototype's `$super` support relies on some ugly things under the covers (like function decompilation).
There's a clunky alternative which you can use anywhere (including within `SectionText`'s `extension` function: `Section.prototype.extension.call(instanceReference, ...)`. Here's an example: http://jsbin.com/iquto5 Or you can go a totally different direction: http://blog.niftysnippets.org/2009/09/simple-efficient-supercalls-in.html Happy coding, -- T.J.
