I'm experiencing some problems on a site with some apparently simple

code. It used to work with jQuery R226, but when I updated to 1.0

final (R231), it broke in Firefox (Mac) with the following error:

Error: $(e.cloneNode(true)) has no properties

Source: http://sgmvoc.optimistweb.org/sites/sgmvoc.optimistweb.org/

themes/clubhouse/scripts/jq.js

Line: 376

It works fine in Safari and possibly other browsers too.

This is in the following code from jquery-1.0.js:

jQuery.swap( e, old, function() {

if (jQuery.css(e,"display") != "none") {

oHeight = e.offsetHeight;

oWidth = e.offsetWidth;

} else {

////////////////

e = $(e.cloneNode(true)).css({

visibility: "hidden", position: "absolute", display: "block"

}).prependTo("body")[0];

//////////////

oHeight = e.clientHeight;

oWidth = e.clientWidth;

e.parentNode.removeChild(e);

}

});

which was last changed in revision 230->231. The problem happens when

doing a plain slideDown() from inside a .click() callback:

jQuery("a.login").click(function(){

jQuery("#header-forms > div").filter(":visible").slideUp("slow");

//////////

jQuery("#login-box").slideDown("slow");

//////////

...

});

in: http:sgmvoc.optimistweb.org/sites/sgmvoc.optimistweb.org/themes/

clubhouse/scripts/jq-clubhouse.js

This is pretty simple jQuery usage, and it works fine with 1.0 final

in Firefox if I extract the immediate markup and try it on a stand-

alone, unstyled .html page. It is only in combination with the other

markup on that page that it breaks. It could be a browser bug, jquery

bug or something in my markup that's messing stuff up, I'm not sure.

You can try it for yourself on:

http://sgmvoc.optimistweb.org/ (click the 'Register' or 'Member log-

in' in the header)

Has anyone got any ideas about this? Have you seen it before?
