Hi,
Is it normal that the application is started twice with the GWT plugin installed (and bootstrap exeuted twice as well)? See highlighted text below.

This is due to the GWT plugin generating the RPC stub files for you, which causes Grails to think that the src/java files have changed and forces the system to restart.
I personally find this a bit inconvenient so I have disabled it. There are two ways to do so: 1) grails -Ddisable.auto.recompile=true run-app, which will essentially disable ALL auto recompile functionality throughout the entire application. Easy way if you're just focused only on the GWT application development. 2) Change the generated Async RPC files and save it so that the modification time is newer than the timestamp file. GWT will then acknowledge that you have manually taken over the creation of the RPC files and will no longer autogenerate those for you. I personally find this more useful. Although I see the benefits of having the plugin auto-generate the RPC interface files, it is unfortunately still a little inadequate for my needs (ie. exceptions are not added to the signature). Thus, I have resorted to just using IDEA IntelliJ's own GWT support mechanism to sync my RPC files. Things work out better that way. I'm also thinking of eliminating the RPC code generation entirely out of the grails plugin itself. Hope it helps, Chris On Jul 22, 2008, at 7:06 PM, Fred Janon wrote:
