Morphia Query not working with collection without element "t"


I have a mongodb collection where there is no element “t” (Added by Morphia when saving any data), and morphia is not able to find the record. If I get the same document and include manually the element “t” it starts to work.

My Question:
There is a way to use Morphia to query an existent database where element “t” representing a Java object is not present?

Thank you
