Controller not finding domain class

Something like this:

I'm seeing lines like that for all of my other domain classes but nothing for 'ProgramType'. It almost seems like hibernate isn't seeing it at all.

[jcroley]

I've changed the code in my controller 3 times. Each time I get a different error message.

If I use this line to get the scaffolding:

static scaffold = ProgramType

I get this error:

2011-08-09 16:22:58,570 [Thread-58] ERROR plugins.DefaultGrailsPlugin - Cannot generate controller logic for scaffolded class class com.xfitlog.ProgramType. It is not a domain class!

If I use this code:

def scaffold = true

I get this error:

2011-08-09 16:20:53,602 [Thread-33] ERROR plugins.DefaultGrailsPlugin - Cannot generate controller logic for scaffolded class true. It is not a domain class!

and if I use the code generated by the generate all command I get this error:

Have you tried removing your 'target' directory and possibly recreating the ProgramType domain class? All the above errors mean the same thing: Grails is not seeing ProgramType as a domain class. Is there no difference between it and the other domain classes?

[jcroley]

I removed the 'target' directory and rebuilt the project. Resulted in the same error.

I tried to create a more complex domain object before 'ProgramType'. That is when I first noticed the error. I created 'ProgramType' as a very simple object to try and isolate the problem.

I'm beginning to wonder If I screwed the project up by introducing a MySQL DB connection in the test environment. Here is my DataSource.groovy code. Let me know if anything looks amiss.

dataSource {
    pooled = true
    driverClassName = "org.hsqldb.jdbcDriver"
    username = "sa"
    password = ""
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = true
    cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update" // one of 'create', 'create-drop','update'
            url = "jdbc:hsqldb:file:devDb;shutdown=true"
        }
    }
    test {
        dataSource {
			pooled = true
			driverClassName = "com.mysql.jdbc.Driver"
			url = "jdbc:mysql://localhost/public" //"jdbc:mysql://localhost/xfitlog"
			dbCreate = "update"
			username = "sa"
			password = ""
			dialect = org.hibernate.dialect.MySQL5InnoDBDialect
        }
    }
    production {
        dataSource {
            dbCreate = "update"
			url = "jdbc:hsqldb:file:prodDb;shutdown=true"
			// AWS RDS
            //url = "jdbc:mysql://ironworkslog.cat4owdsmbkz.us-east-1.rds.amazonaws.com:3306/ironworkslog"
			//Instance: IronWorksLog
			//UserName: ironworks_user
			//Password: xfitLogBitch
        }
    }
}

Thanks for your continued help!!

Okay. I ran a little experiment. I had a test project on the same machine. I added a 'ProgramType' domain object and controller to that project and set 'def scaffold = true'. Everything worked fine.

This tells me that there is definitely something wrong with the 'xfitlog' project. Now all I have to do is figure out what that problem is!
