MissingMethodException on domain class save in Grails 1.3.7 - grails

Question

I'm having a problem calling the save method on a domain object. The error is:
groovy.lang.MissingMethodException: No signature of method: static my.awesome.Class.FeedHit.save() is applicable for argument types: () values: []
Possible solutions: save(), save(java.lang.Boolean), save(java.util.Map), wait(), any(), wait(long)
I'm going through an array of FeedHits, updating a flag, and then calling the save method:
void updateFeedHits(Set<FeedHit> list, FeedHitStatus status) {
for (FeedHit feedHit: list) {
feedHit.status = status
try {
feedHit.save()
} catch (Exception ex) {
log.info("unknown exception during update FeedHit", ex)
}
}
}
I've seen other StackOVerflow users have the same problem, but only during tests. This code is in normal release code.
Any help would be appreciated.
EDIT:
Here is the FeedHit object, slightly edited.
class FeedHit {
Feed feed
String title
String body
String url
FeedHitStatus status
String sourceId
String hash
Date publishedDate
Date dateCreated = new Date()
Integer pos = -1
static constraints = {
alert(nullable: true)
title(nullable: true)
body(nullable: true)
url(nullable: true)
status(nullable: true)
sourceId(nullable: true)
hash(nullable: true)
pos(nullable: true)
publishedDate(nullable: true)
dateCreated(nullable: true)
}
static mapping = {
table('alert_hit')
autoTimestamp false
version(false)
alert(column: 'alert_id')
body(sqlType: 'text')
url(sqlType: 'text')
sourceId(column: 'sourceId')
publishedDate(column: 'publishedDate')
dateCreated(column: 'dateCreated')
}
/**
* Generates a hash from title, body and url.
*/
public AlertHit generateHash() {
StringBuffer sb = new StringBuffer();
if (this.title != null) {
sb.append(this.title);
}
if (this.body != null) {
sb.append(this.body);
}
if (this.url != null) {
sb.append(this.url);
}
if (this.publishedDate != null) {
sb.append(this.publishedDate.getTime());
}
if (sb.length() > 0) {
hash = Md5Hash.hash(sb.toString());
}
this
}
#Override
public String toString() {
return "AlertHit{" +
"id=" + id +
", alert=" + alert +
", title='" + title + '\'' +
", body='" + body + '\'' +
", url='" + url + '\'' +
", status=" + status +
", sourceId='" + sourceId + '\'' +
", hash='" + hash + '\'' +
", publishedDate=" + publishedDate +
", dateCreated=" + dateCreated +
", pos=" + pos +
", version=" + version +
'}';
}
}

You need to annotate GORM functions, if you want to use domain class outside grails. See http://www.rimerosolutions.com/using-gorm-standalone-outside-grails/
I would recommend you to use another way than native threads. Try: Quartz-Plugin
