When I redirect to a new page,it always show a message "Processing..." in the middle of the screen,but I have set locale value in session zh_CN,like

session.setAttribute(Attributes.PREFERRED_LOCALE, zh_CN_Locale_Value)

it still shows the English messge instead of Chinese,all other message works fine except this one,I'm using zk CE 6.5.3.thanks for your help.
