After upgrading Grails withCriteria query no longer working

Question

I recently updated a Grails project to the latest 2.x version, 2.5.0, along with all the dependencies, including Hibernate, which is now at 4.3.5.2.

Everything mostly works, ie the database is writing/retrieving values fine, controllers do their thing, Spring security works, etc. However, now one of the model queries using withCriteria is throwing a weird error.

The two domain classes look something like this:

class MyModel1 {
   Integer status
   MyModel2 model2
}

class MyModel2 {
   Integer range1
   Integer range2 
}

And then I have this method that does a query that checks the "range" fields of the sub-model:

public List<MyModel1> doThing(int low, int hi) {

    return MyModel1.withCriteria {
        eq("status", SomeStatus.FLAGGED)
        model2 {
            between("range1", low, hi)
            between("range2", low*2, hi*3)
        }
    }
}

Prior to upgrading, this code worked fine. Now it complains with the following exception:

could not resolve property: model2_alias0 of: com.example.MyModel2. Stacktrace follows:
org.hibernate.QueryException: could not resolve property: model2_alias0 of: com.example.MyModel2

(Additionally, I'm using IntelliJ, and when I highlight the between() statements in the above withCriteria block IntelliJ informs me that it "Cannot resolve symbol 'between'". Maybe not relevant, IDK.)

Answer 1

So it appears that the problem was with the version of Hibernate to which I'd updated.

The clue was in the 2.5.0 GORM docs where it states:

Under the hood it uses Hibernate 3 ...

I was trying to use v4, as I state above. I switched back to the latest version of 3. Put the following in BuildConfig.groovy :

plugins {
   runtime ":hibernate:3.6.10.19"
}

Also had to switch this line in DataSource.groovy :

hibernate {
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // had been this: 'org.hibernate.cache.ehcache.EhCacheRegionFactory'
}

After that, everything works as it should. (Also, IntelliJ still complains about the between clause, so apparently, not relevant.)
