fn is not a function

map([a.toggle wms.portal], undefined)jquery.js (line 581)

(no name)("fieldset:first")jquery.js (line 635)

(no name)()jquery.togglehtml... (line 18)

handle(click clientX=0, clientY=0)jquery.js (line 1202)

[Break on this error] var val = fn(elems[i],i);

$(this).click(function() {

$(this).parents('fieldset:first').children().not("legend").toggle();

return false;

});

Works in 1.0.4
