I just downloaded the latest trial version of GWT Designer 1.6 20070314 build and I got some problems (environment, eclipse 3.2 + WTP 1.5.3 + gwt-yui-ext 3rd party GWT widget). Here attached my eclipse project and any advice are hightly appreciated. Thanks:)

1) right click on the src/newGriffin/gwt/MainImpl.gwt.xml, run as GWT Application, it popup a run wizard with a alert "Module HTML MainImpl.html does not exist. If I browse for the html, it always filters all the html file except com.google.gwt.core.Core/history.html. so I must rename the MainImpl.html to MainImpl.htm in order to make it run.

2) right click on src/newGriffin/client/gwt/MainImpl.java and run as GWT Application, no response at all.

3) Open the src/newGriffin/client/gwt/MainImpl.java and switch to Design tag, the GWT Designer popup a alert box "com.swrdesigner.properties.PropertyException: java.lang.reflect.Invocation.TargetException"

1. Don't use multiple modules in a single package.

2. Don't place one module inside another.

3. An exception fragment isn't helpful (we need to see the complete Eclipse ".log" file).

1. Don't use multiple modules in a single package.

But even google use multiple modules in a single package (com.google.gwt.user).

And it seems not the reason of the Q1

1. Don't use multiple modules in a single package.

But even google use multiple modules in a single package (com.google.gwt.user).

"Even google" does not provide GUI builder for GWT.

Problem with multiple modules in same package is that when you open GUI class, you need to exactly know to which GWT module it belongs. We need this to create correct class loader and support loading of public resources.

For example, if there is modules A and B in same package and in "client" there is GUI class that references some 1.png image. But modules A and B have different "public" folders, so we don't know where to look for image - in "public" of A or B.

And it seems not the reason of the Q1

Eric will give you better answer on Q1.

But it works for me - I can select "HTML", "HTM" and even "HtmL" files.
