Hi, I want to fetch a list with two different objects but I cant figure out how to do this.

The list is supposed to contain the four most recent posts from the two tables which means that it could be either two from each of them or three from one and one from the other or four from the same table.

Hope anyone can give me a hint on how to do this.

What is the relationship between these two different objects?
If there are none, it is impossible AFAIK...

You may select the four lastest of each Types and then merge them to keep only the four lastest of both (throwing the four others).
