Currentlly, I am working on a web dynpro dc which contains multiple components. One of the component called "CommonComp" which is a dummy component (without view) which act as a centralise location to store all messages that use by other components.
When I try to display an error message "NO_USER_FOUND" in the message area of other component's view, the message text was not display but the message key "message.NO_USER_FOUND" was display in the message area
wdComponentAPI.getMessageManager().reportMessage(IMessageCommonComp.NO__USER__FOUND, null, false);
