Re: RequestFactory can not support embedded class and owned 1-to-many in one Entity
Hi David,
Yes, i am trying request like
"findUrlMd5Req.with("pTagSet", "pTagOwnedSet").fire", where pTagSet
and pTagOwnedSet are defined in an entity class.
"
@Persistent (defaultFetchGroup="true")
@Embedded
private PTag pTagSet;
..
@Persistent(mappedBy="bookPTag", defaultFetchGroup="true")
@Element(dependent = "true")
private List pTagOwnedSet= new ArrayList();
PTagProxy is defined as
@ProxyFor(value=PTag.class)
public interface PTagProxy extends ValueProxy {
..
PTagOwnedProxy is defined as
@ProxyFor(value=PTagOwned.class, locator=locator-for-pTagOwned)
public interface PTagOwnedProxy extends EntityProxy {
"
As I said, if containing only embedded class or owned 1-to-many class,
it works. Combined two type of classes above will return only owned 1-
to-many proxy.
Is it a limitation on the implementation? How to debug in this case?
Thanks,

RequestFactory can not support embedded class and owned 1-to-many in one Entity
Hi, I have one question about RF proxy support. I am using gwt2.1.1 and jdo in appEngine 1.4.0. I found out if a Entity class contains both owned 1-to-many subclass and embedded class. Then, RF only return owned 1-to-many proxy. If it contains only embedded class or owned class, then RF works fine. Is it a limitation of current release of RF or any other reason?

Re: How to return nested 1-to-many EntityProxy
Hi Y2i,
Sorry to make you mis-understand.
I am query PTagLinks, which contains list of PTagOwned class, which
contains list of RIdxWord class.
As I said, i have tried multiple combinations of request 'with'. Even
i changed to "Req.with("pTagOwnedSet.grandChildren").fire". I can
still see PTagOwned list. RIdxwordProxy list in PTagOwnedProxy will be
null.

In the case of , how can you "query set little by little" in 2nd
level? please suggest. Thanks,

Re: RequestFactory does not preserve owned 1-to-many list order
Hi David, Thanks for the reply. What i want is support for 'collection' of embedded classes. I am using gwt2.1.1 + appengine sdk 1.4.0. What i found is jdo implementation in appEngine seems not support this feature. I saw your sample code of 'listwidget' by JPA. it seems ok. Is it correct?

Re: How to return nested 1-to-many EntityProxy
Hi Y2i,
I have tried suggestion from Thomas Broyer with various combinations
on 'with' clause but does not work. From debug inf, i can see 'PTag'
class been retrieved but not 'RIdxWord'. my sample code is the
following:
"
class PTasLinks {
..
/* 1st layer owned 1-to-many relationship */
@Persistent(mappedBy="bookPTag", defaultFetchGroup="true")
@Element(dependent = "true")
private List pTagOwnedSet= new ArrayList();
..
}
class PTagOwned {
..
/* 2nd layer realtionship */
@Persistent(mappedBy = "bookPTagOwned", defaultFetchGroup="true")
@Element(dependent = "true")
private List grandChildren =
new ArrayList();
..
}
Req.with("pTagOwnedSet.grandChildren").with("pTagOwnedSet").fire
"
I wonder if layered access cannot be complete in one request. Then, it
will need another request to complete. Is it necessary? Please help to
clarify. Thanks

How to return nested 1-to-many EntityProxy
Hi, I have made layered 1-to-many relationship, says, parent-children- grandchildren. It works fine to access grandchildren from children in server. But passing back as 'null' of grandchildren thru requestfactory. I am using request with( propertyRefs). Even multiple with(propertyRef1).with(propertyRef2) does not work, where propertyRef1 for child's and grandchild property.

Re: RequestFactory does not preserve owned 1-to-many list order
Hi Thomas, you are correct in list order. It's my mistake. For the second question, i have tried @Persistent(embeddedElement="true") on collection of embedded class,but does not work on appEngine sdk 1.4.0. Can you provide a working example? Is it possible to have embedded class or collection of embedded class on a child entity of owned 1-to-many relationship. Another question confused me is in RequestFactory doc says "It is not necessary to represent every property and method from the server-side entity in the EntityProxy, only getters and setters for properties that should be exposed to the client." Does it mean RF will smart download only properties specified in EntityProxy or it will download whole property set no matter what.

RequestFactory does not preserve owned 1-to-many list order
Hi, I am using gwt2.1.1's requestfactory on owned 1-to-many relationship in jdo. I found the ordering of child list is missing as passed back to entityproxy. Another question is jdo seems not support collection of embedded class. Even RF enables embedded class in new release. This makes coding difficult.
