Also, you can compile in PRETTY mode using the Google Eclipse Plugin by following the steps below: 1) While your project is open, click on the "Run..." drop-down arrow to open the list of run configurations.
2) Select "Run Configurations..." 2) In the Run Configuration dialog, select your project's Web Application launch configuration. 3) Navigate to the GWT tab 4) Select the "Pretty" option from the Output style drop-down box. 5) When you hit "Compile/Browse" on your next hosted mode launch, the generated output will be human-readable JavaScript. This will either give us more hints in the generated error message, or will work in Firefox 3, in which case there may be something to investigate on the GWT side of things.
