Hi there, congratulations for 1.6.3.
I just tried the 1.6.3 build (BTW, I spent more half an hour crawling on around ten or more swingx websites /maven repository website/ tickets systems and finally found in some obscure forum thread that the artifact download is available from the Swingx Nexus at  , I guess the download link is not that obvious or is it me ?)
Unfortunately, the bug is still there (or is it a similar one?) . For instance, I have in my list : "Unknown",
I type : "U n K" , swingx forces : "U n k" instead so I cannot type "UnKown", "Unknown" is forced.
I am thus stuck for now with my fix (see my code previously posted on this ticket).
Thanks for consideration.
