GWT Example Project (desktopclone)

Postby tohkawa » Sun Jan 28, 2007 7:24 pm

I'm evaluating gwt designer of the latest version on eclipse 3.2.1, but with example project downloaded from http://code.google.com/webtoolkit/docum ... ktopclone/
I couldn't open design tab for Mail.java. It resulted in "java.lang.reflect.InvocationTargetException".

Any suggestion?

stacktrace follows:

Yes. This example throws an NPE at design time (it's not very carefully written), so you need to fix the following NPE (from your log entry)...

Code: Select all
java.lang.NullPointerException
   at com.google.gwt.sample.mail.client.MailList.selectRow(MailList.java:144)
   at com.google.gwt.sample.mail.client.MailList.update(MailList.java:192)
   at com.google.gwt.sample.mail.client.MailList.<init>(MailList.java:70)

If you comment out the line Mail.get().displayItem(item); in the MailList class, the Mail class should open in Designer.
