The Jive input screen lets you select lowercase letters right?

I tried it...From the Rename station screen lower case letters do not show. 

It all depends on what the string of accepted characters is set to for that text input window. SqueezeCenter's strings.txt file allows two different sets, one with upper and lower, and one with just lowercase (interestingly, none with just uppercase).

JIVE_ALLOWEDCHARS_WITHCAPS
JIVE_ALLOWEDCHARS_NOCAPS

On the jive side, there is a string that will deliver only caps (ALLOWEDCHARS_CAPS)...so perhaps XMLBrowser is sending that string across untranslated and has Jive do it?

what's happening is that nothing is being sent for "allowedChars" from SC, so jive is defaulting. It defaults to all caps no lowercase.

from SlimBrowserApplet.lua:

-- default allowedChars
if not inputSpec.allowedChars then
      inputSpec.allowedChars = _string("ALLOWEDCHARS_CAPS")
end

In order for this to work there would need to be some kind of identification within XMLBrowse of what set of allowedChars to use. I'm not sure that it's possible to identify this item differently than something like Pandora or Rhapsody search, which I don't think you'd want lowercase to be available for...

Yeah, I think having lowercase for normal search fields would be wrong, which would make this a won't fix.

Understood for the search field but what about for renaming a station? Shouldnt there be lower case letters for that?

the problem is that there is no way for SC to differentiate search from rename station. Both are textinput fields delivered via XML from Pandora and don't have any metadata to allow us to decide which character set to use.

it's a good request, but somewhat impossible to fill.
