grails - error executing bootstrap (Error creating bean with name 'messageSource')

Question

I made some seemingly harmless changes (added a few domain classes, added the plugin shopping-cart), and now apparently the BootStrap.groovy class doesn't execute at all.

While I made a few changes to BootStrap.groovy, I restored a previously good file that works fine, dumbfounded by the error. Also, in the good (old) BootStrap.groovy, I put some println statements at the top of the init action, but those aren't printing out and don't seem to even be reached. Finally, I did an uninstall of the plugin, and after that, deleted the shopping-cart plugin folder manually.

Do you know what this error is, or have any debug guidance? (am running Grails 1.3.7)

Answer 1

I would guess that you have a problem in one of your domain classes where you use a "def" or some other invalid type in the domain class for one of the fields.

Answer 2

I removed all the new domain classes and references to them, and the error went away. I'll update this as soon as I figure out what the problem is, hopefully not related to a domain change to one of the Spring Security classes (User).

Ok, the problem is/was, I had an enum declaration at the top of one of the domain classes I added. If I move the enum declaration below the class declaration, then all is good. I imagine this is a hibernate error / problem?
