I copied the source from the jqxexpander demo and i got this error in firebug when trying it out:
Error: Syntax error, unrecognized expression: .jqx-expander-header-boot=1&lang=en&cookie=&sid=ub227spemj0ml5qlm3cf71j1v4

I noticed that it was only happening when i used url parameters or post variables to the page that i was using the example. I then debugged and found out that it had something to do with the lines that get the theme:
theme = gettheme();
So i removed the theme script, every line that had to do with that js file and then used the css styling method in the documentation:
…jqx.summer.css
and everything works well.
This has something to do with jQuery, as when i use version 1.7.2 in contrast to 1.8.1, it works well without removing the get theme thingy. However, i use the latest version of jQuery all the time and might actually switch to the latest 1.8.2 just now and test my code.
I didn’t further my research into the gettheme script since all i wanted now works.
I thought of just posting this here since i couldn’t find any help googling.
