    <p>I have couple of POJOs:</p> <pre><code>public class FlightBase { public AirportBase getDeparture() { return departure; } public void setDeparture(AirportBase departure) { this.departure = departure; } public AirportBase getDestination() { return destination; } public void setDestination(AirportBase destination) { this.destination = destination; } public String getDetails() { return details; } public void setDetails(String details) { this.details = details; } String details = ""; AirportBase departure; AirportBase destination; } public class AirportBase { String icaoIdentifier = "KSPG"; public String getIcaoIdentifier() { return icaoIdentifier; } public void setIcaoIdentifier(String icaoIdentifier) { this.icaoIdentifier = icaoIdentifier; } } </code></pre> <p>... I'm trying to use these as domain classes in a grails app by extending them:</p> <pre><code>package flightloggrails import com.flightloglib.domain.AirportBase import com.flightloglib.domain.FlightBase class Flight extends FlightBase { static hasOne = [departure:AirportBase, destination:AirportBase ] static mapping = { departure type: Airport destination type: Airport } static constraints = { details( blank:false,null:false, widget:'textarea') } } </code></pre> <p>and this domain class :</p> <pre><code>package flightloggrails import com.flightloglib.domain.AirportBase class Airport extends AirportBase { static constraints = { } } </code></pre> <p>... keep getting this trying to execute 'run-app' (preceded by 'clean') :</p> <pre><code> Error 2012-04-24 06:50:18,892 [pool-5-thread-1] ERROR context.GrailsContextLoader - Error executing bootstraps: Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: Could not determine type for: flightloggrails.Airport, at table: flight, for columns: [org.hibernate.mapping.Column(departure)] Message: Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: Could not determine type for: flightloggrails.Airport, at table: flight, for columns: [org.hibernate.mapping.Column(departure)] Line | Method -&gt;&gt; 303 | innerRun in java.util.concurrent.FutureTask$Sync - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 138 | run in java.util.concurrent.FutureTask | 886 | runTask in java.util.concurrent.ThreadPoolExecutor$Worker | 908 | run in '' ^ 662 | run . . in java.lang.Thread Caused by BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: Could not determine type for: flightloggrails.Airport, at table: flight, for columns: [org.hibernate.mapping.Column(departure)] -&gt;&gt; 303 | innerRun in java.util.concurrent.FutureTask$Sync - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 138 | run in java.util.concurrent.FutureTask | 886 | runTask in java.util.concurrent.ThreadPoolExecutor$Worker | 908 | run in '' ^ 662 | run . . in java.lang.Thread Caused by BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: Could not determine type for: flightloggrails.Airport, at table: flight, for columns: [org.hibernate.mapping.Column(departure)] -&gt;&gt; 303 | innerRun in java.util.concurrent.FutureTask$Sync - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 138 | run in java.util.concurrent.FutureTask | 886 | runTask in java.util.concurrent.ThreadPoolExecutor$Worker | 908 | run in '' ^ 662 | run . . in java.lang.Thread Caused by MappingException: Could not determine type for: flightloggrails.Airport, at table: flight, for columns: [org.hibernate.mapping.Column(departure)] -&gt;&gt; 303 | innerRun in java.util.concurrent.FutureTask$Sync - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 138 | run in java.util.concurrent.FutureTask | 886 | runTask in java.util.concurrent.ThreadPoolExecutor$Worker | 908 | run in '' ^ 662 | run . . in java.lang.Thread </code></pre>

    1. COI'm not 100% sure but I believe that a domain class must extend another domain class and not a POJO/POGO. I could be wrong though.

    2. COAll seemed fine until I tried adding the mapping. Otherwise 'generate-all' for the Flight class created all the CRUD artifacts just fine.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
