How may I retrieve both idPic and title in a single efficient query?
Something like
Query q = new Query(select idPic, title from +
TPImage.class.getName());
but more efficient?
Thank you very much!

Do they throw an exception? what else? I cannot find such hints in the
documentation.
Moreover, when the method cache.clear() fails throwing the exception,
may I assume that the cache will be empty the next time I use it or
not?
Thank you very much!

Hi Roberto,
thanks for the response.
I think I'll have to proceed in the manual way as you said; I hoped
not to perform such action as the automatic way is far better!!
Do you know how many days (more or less) they need to update the
plugin to the latest version?
Thanks

@Nathan: I use ArrayList for a bounch of other properties in several
other objects, and usually they are completely OK...

OK, thanks, I'll try with this trick...

any other graphic utility to perform such action.
Perhaps this action is not permitted for child entities...
Any hints about this?

Hi Yegor, thanks for your suggestions.
But I yet cannot understand how to cope with transactions in the
scenario you have described.
Let's say that I have the following (usual) example:
public class User {
Long userID; //it is the PK of the object
ArrayListContact contacts;
...
}
public
the Datastore viewer of
the admin console: you can select and delete all entities from the
viewer screen.

to JDO and GoogleAppEngine or am I forced to use the same instance of
PersistenceManager both to fetch and save the data?

Hi everybody,
I'm struggling with a strange problem with JDO.
I've got two PersistenCapable classes, one having a Collection of
objects of the second, something like this:
class First {
@Persistent
@PrimaryKey
Long id;
@Persistent(mappedby=owner)
ArrayListSecond list = new
= new ArrayListSecond();) results in any
strange behavior?
4) Do I need to add any other annotation to owner field of Second
class?
Thank you very much for your help!!
