title: What are your favorite Grails debugging tricks?
body: <p>Grails can be a bit of a bear to debug with its long stack dumps.  Getting to the source of the problem can be tricky.  I've gotten burned a few times in the BootStrap.groovy doing "def foo = new Foo(a: a, b: b).save()", for example.  What are your favorite tricks for debugging Grails apps?</p>
