NO GUI Roots detected

Postby redlifejacket » Thu Nov 06, 2008 2:25 am

GWT Designer Version:
GWT Version: 1.5.2
Eclipse Version: 3.4.0
Java Version: JVM 1.5.0 (Mac OS X Default)
Operating System: Mac OS X 10.5.5

Hi there,

In GWT Designer, when I create a Composite and click on the Design view, I obtain the following error:
"Designer was unable to find any GUI elements in your source. Check that the open compilation unit is a GUI class."
Please refer to attached screenshots and the ImageViewer project zip file.
Could you please shed some light.

GWT Designer v5.0.0 predates and does not support GWT 1.5.

You need to install GWT Designer v5.1.0 if you want to use GWT 1.5 (as stated on our web site and many times in this forum).
