Designer was unable to find any GUI elements in your source.

[AethelJack]

Been trying to get Designer working, and am at an impasse. Opening the Demo project and clicking on "Design" produces a dialog with this title and text:

-------------------------------------------------
No GUI roots detected

Designer was unable to find any GUI elements in your source.
Check that the open compilation unit is a GUI class.
-------------------------------------------------

... and an exception with a trace that I've pasted at the bottom.

The little demo app works fine when I run it, popping up a web page with a clickable button and all, so it seems like GWT is working fine with Eclipse.

But there is no working Designer. I see the basic organization of Designer's elements, but the Palette, Property Editor, etc., are all empty and the work space is titled "Unknown Window Type".

Eclipse isn't hung, I can go back and edit the source, save my changes, and run it again.

I'm using Ubuntu amd64, Eclipse 3.3 (amd 64) running in sun-java-6 (64 bit). The project runs in ia32-sun-java-1.5.

What does Designer need that it can't find, and how do I point it there?

Cheers,


Jack

Unfortunately, GWT does not support 64-bit linux.

See http://code.google.com/p/google-web-too ... ail?id=135 for details.

Currently, we are in the process of investigating a way around this limitation. You might try running Eclipse (with Designer) using 32-bit Java.

I did read that thread, and a few others. Specifying a 32-bit JVM for the project seems to keep GWT happy.

I installed VMWare, and WinXP Pro in that, and now have Eclipse, GWT, and GWTDesigner running virtually. It's probably not a long-term solution but at least now I can evaluate the tool.

My first impressions are very positive. I'd be interested to keep up with whatever progress is made trying to find a solution, and am willing to test and give feedback.

Cheers,

I did read that thread, and a few others. Specifying a 32-bit JVM for the project seems to keep GWT happy.

Since GWT is also being run within Eclipse, it is also important to run Eclipse with a 32-bit VM as well.

My first impressions are very positive. I'd be interested to keep up with whatever progress is made trying to find a solution, and am willing to test and give feedback.

Once GWT provides native 64-bit Linux support, we will also be able to support that configuration as well. The only issue at this point is in GWT itself.
