you cuold edit the app-engine plugin:
C:\Documents and Settings\pm\.grails\1.1.1\projects\grails-gae\plugins
\app-engine-0.8.5\scripts\_Events.groovy
inside <system-properties> element add:
<system-properties>
<!-- this property should be necessary. it avoids the report of
an abnormal and unexpected situation!
<property name=\"appengine.orm.disable.duplicate.emf.exception
\" value=\"true\" />
<property name="grails.stringchararrayaccessor.disabled"
value="true"/>-->
<property name="stringchararrayaccessor.disabled" value="true"/>
</system-properties>
it work for me. hope helpfull.
