I’m using DateField, when I click the icon the popup calendar looks fine in Vaadin 7.0.5, but the month name and day names are displayed as “null” in version 7.1.1.

Can someone help?

It’s not happening to me. Do you have any special locale settings?

Actually the problem occurred when I updated the Vaadin version from 7.0.5 to 7.1.1 by modifying
<vaadin.version> in pom.xml.

Is there anything else I need to change?


You have to recompile your widget sets when you change your vaadin version. Have you done that?.

I ran “Compile Widgetset” in Eclipse and got the error:
Error: Could not find or load main class
Widgetset compilation failed

Since you are using maven you shouldn’t let the eclipse plugin compile your widgetsets. Use maven for that.
Take a look at this page from the book of vaadin:
Vaadin & Maven
