getPersistentValue throw a NullPointerException in Unit Test

Hello,

It seems that now (in grails 2.3.1 and over) there is a posibility to access
getPersistent value and other isDirty property, but when calling
getPersistentValue from any Domain Class I've got a :

java.lang.NullPointerException
at
org.grails.datastore.gorm.GormInstanceApi.getPersistentValue(GormInstanceApi.groovy:305)

And impossible to "mock" by :
MyDomain.metaClass.static.getPersistentValue = {String s -> return null}

Any idea to get around this bug (isDirty seems to work, at least no
execption...)

Regards

At some point there was some discussion about adding a makeDirty() method
for unit testing. I'm not sure if that solution was ever implemented but
might be worth checking.

Did you ever figure out the proper way to implement this in 2.3?

I wonder if the inability to metaClass things is because more and more of
this stuff is marked as @CompileStatic.
