Subject [jira] [Commented] (WW-4307) s:combobox is causing an error
Date Tue, 25 Mar 2014 05:51:44 GMT

Lukasz Lenart commented on WW-4307:
-----------------------------------

So maybe one of beatNames' elements is null? Maybe Eclipse is messing things? Have you tried
deploy to servlet container and check there?

The same example works very well in Showcase app, have you checked that? Did you follow any
tutorial? Can you post the source of generated html page? Can you ask questions on user mailing
list before registering issue?
