    text
    copied!<p>I am having troubles with using the findOrCreateBy method in the Bootstrap.groovy. </p> <pre><code>class Guest { String firstname String lastname Gender gender static constraints = { firstname blank: false lastname blank: false gender nullable: false } } enum Gender { MALE('male'), FEMALE('female') final String v Gender(String s) { v = s } } </code></pre> <p>And in the Bootstrap I try to create Guests if they do not exist yet.</p> <pre><code>Guest guest = Guest.findOrCreateByFirstnameAndLastnameAndGender(firstname, lastname, Gender.MALE) guest.save() </code></pre> <p>The first time I run the app against MySQL everything works fine. The apps starts without any error. If I run the app a second time (this time with guest in the database) I get the following failure.</p> <pre><code>| Error 2013-11-17 14:27:37,621 [localhost-startStop-1] ERROR context.GrailsContextLoader - Error initializing the application: Unknown name value [1] for enum class [ch.silviowangler.ch.cisposiamo.Gender] Message: Unknown name value [1] for enum class [ch.silviowangler.ch.cisposiamo.Gender] Line | Method -&gt;&gt; 105 | methodMissing in org.grails.datastore.gorm.GormStaticApi - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 106 | createGuest in BootStrap | 102 | createGuest . . . . . . . . . . in '' | 66 | doCall in BootStrap$_closure1 | 308 | evaluateEnvironmentSpecificBlock in grails.util.Environment | 301 | executeForEnvironment in '' | 277 | executeForCurrentEnvironment . . in '' | 262 | run in java.util.concurrent.FutureTask | 1145 | runWorker . . . . . . . . . . . in java.util.concurrent.ThreadPoolExecutor | 615 | run in java.util.concurrent.ThreadPoolExecutor$Worker ^ 744 | run . . . . . . . . . . . . . . in java.lang.Thread </code></pre> <p>It seems the the first time Gorm writes values '0' and '1' to the database. In the second run it fails to convert these 0 and 1 into the corresponding enum value. Can anybody tell me what I am doing wrong?</p>
