Hi, We're using jQuery with GWT and, long story short, here's what happens:
A third-party GWT module (let's call it "chicken") includes jQuery and makes some additions to the jQuery object. Along comes another GWT module (let's call it "tuna") that also includes jQuery and, without the ability to control the order in which both modules are loaded, the contents of jquery.js is included/executed twice during page load, resulting in the loss of the additions made by the "chicken" module. In other words, the <body> element would contain something like this: <SCRIPT language="javascript" src="gwt.application.nocache.js"> </SCRIPT> <SCRIPT language="javascript" src="http://localhost:8888/gwt.application/js/chicken/jquery.js";> </SCRIPT> <SCRIPT language="javascript" src="http://localhost:8888/gwt.application/js/chicken/jquery.additions.js";> </SCRIPT> <SCRIPT language="javascript" src="http://localhost:8888/gwt.application/js/tuna/jquery.js";> </SCRIPT> Now, since the "tuna" module is not always used alongside the "chicken" module, it can't not (i.e. it must) include jsquery.js, and the reverse is also true. We think the simplest and best way to fix this problem is simply to have jquery.js be safe to include more than once and thus we are proposing the attached patch, which makes all of [the generated] jquery.js conditional upon having not executed already.
