Hi,

I'm getting a lazy init exception in the MassIndexer on a field that is marked as
@Transient
@Field(index=Index.NO,store=Store.YES)
public String getLabel(){
return name + this.getRegion().getLabel();//region is @ManyToOne, fetch=FetchType.LAZY
}

I expect it has to do with the fact that the field is Transient but at the same time, the error does surprise me

Hi,

looking at the stacktrace it looks like getLabel is getting called after the session is closed. Are you sure your session is still open when you make the call?
The transient annotation will ensure that there is no value loaded or stored for this property. I don't think this is a problem in combination with @Field.

It looks like the Transient aspect was irrelevant. The problem seems related to the use of optional=true in a ManyToOne relation.
I described everything in more detail in this thread:
