Hi,

I'm new to GWT am currently working on the tutorials at https://developers.google.com/web-toolkit/tools/gwtdesigner/tutorials/

I have a problem with the login function tutorial. In part 7, I get a problem when I'm asked to Launch default browser. A new tab opens in Chrome but the page stays blank. I tried to copy the whole source code from the tutorial to get it working but it's still blank.

The second tutorial, when I run as a web application, works though.

Any suggestions?

Thanks a lot!

Welcome to the Ranch.

1) Do you see any errors on your eclipse console?
2) What do you see if you right click on your browser page and select view source?
