[Lift] Re: strange interaction with jQuery
Marius, Agreed on two points: - JsRaw is not the culprit -- it seems to be a bad interaction with version of JavaScript modules - JavaScript is the source of the meta problem -- there's no way to get the compiler to warn about this because this world is devoid of useful typing info. It would appear that a vast number of web technologies have accepted a programming model proposition that is predicated on typelessness. 'This has all happened before and it will happen again.' It looks like i'm going to have to resurrect my rhoscript project. Best wishes, --greg On Sat, Feb 14, 2009 at 2:20 PM, Marius marius.dan...@gmail.com wrote: Interesting ...

[Lift] Re: strange interaction with jQuery
How about a defect as a result of upgrading jQuery to 1.3.1?
