Hello,
Error on Server Console : HTTP JVM: SEVERE: CLFAD####E: Exception processing XPage request.
The above error get printed in server log in most launch failure of xpage,I tried creating an edit field of type date in an already existing xpage binded it to backend date field and it launched 100%. You can try cleaning and rebuilding the project,also try to play around with an xpage having single edit field launch and check also for more error clarity in application properties xpage tabe check "Display default error page" in erros and timouts section will help you to obtain correct error cause.
