answer:I’m sure you saw it, but just in case. Please note that the jQuery Mobile Download Builder is still in alpha, and as such should not be used on production websites. But, let’s see if we can get it fixed. I’d look for the error you’re getting with your custom build, it probably references a function that is missing (“function drhat() doesn’t exist at line 10892”) and then track that one down and make sure to get it included. While it might be browser specific, most likely it isn’t so a desktop browser with whatever tools you like would probably be a good place to start. (something like firebug will give you a place to start) If it’s not happening on desktop browsers, then iphone and android have some pretty good emulators you can run depending on your environment. The developer tools aren’t as complete, but you can at least get a console. Or, if the problem isn’t giving you any hints to work with, start heavy and create a bigger build than you want that works, then weed out the unneeded sections one at a time. Until it breaks.
