Hi,
I was wondering is there any way to change default ‘base’ theme for CJuiDatePicker?
Attribute ‘theme’ works for all widgets which I used… but no for DatePicker 
After changing ‘theme’ in this widget DatePicker is not appear… Firebug shows that datepicker divs are on it’s place, but I can’t do them visible… I changed themeUrl, css file for theme is included (another widgets works). Hmm… Any ideas?
Just verified that this works for me
...
'widgetFactory'=>array(
'class'=>'CWidgetFactory',
...
'widgets' => array(
...
'CJuiDatePicker' => array(
'themeUrl'=>'/js/jquery-ui-1.8/themes',
'theme'=>'ui-lightness',
//'scriptUrl'=>'/js/jquery-ui-1.8/ui/minified',
),
),
),

'widgetFactory' => array(
'widgets' => array(
'CJuiTabs' => array(
'themeUrl'=>$baseUrl.'/js/jui/css',
'theme'=>'redmond',
'options'=>array(
'collapsible'=>false,
),
'htmlOptions'=>array(
'style'=>'min-height:400px',
),
),
'CJuiDatePicker' => array(
'themeUrl'=>$baseUrl.'/js/jui/css',
'theme'=>'redmond',
'language'=>'pl',
'options'=>array(
'dateFormat'=>'yy-mm-dd',
),
),
),...
This not working for me 
Works for tabs, not working for datepicker.
Only difference in folders with jui theme is that in redmond theme, I have only one, main ‘jquery-ui.css’ file, and in base theme there are many files for all widgets separately. Could that be an issue? I could’t find complete theme files on JqueryUI site… only that one file
I couldn’t either… seems like they don’t offer the complete set of themes in one file anymore.
Attached you’ll find the themes I downloaded last year.
