GRAILS-2808: Validation of collection minSize works only after entity was persisted

[graemerocher]

Original Reporter: vlad.shevchenko
Environment: Grails 1.0.2, Java 1.5.0_13, Mac OS X 10.5.2
Version: 1.0.2
Migrated From: http://jira.grails.org/browse/GRAILS-2808

I have domain like:

{noformat}
class Profile {
String name
…

```
static hasMany = [categories: Category]

static constraints = {
name(size: 6..30)
categories(minSize: 1)
…
}
```

{noformat}

When I trying to save with correct name – entity saved successfully! Then I trying update it with no changes, and only now got validation error messages about minimum size of collection.

I think the workarounds Peter provides a valid to resolve this issue

I think this should be fixed somehow since this is really confusing. The minSize attribute of collections is still only working when nullable: false is set.
