I wanted to experiment with custom subscription management. The
documentation states to override handlesSubscriptions() and return true,
plus implement manage(CommandMessage message).I never see my
handlesSubscriptions() method called, so my manage(..) method is, of
course, never called. Is there something else I need to setup?-S
I have two scenarios. One works one and one does not and I cannot
determine the underlying reason. I open two clients make a change in
one. The second client is updated nicely with first scenario and doesn't
update with second scenario.This works:[Managed]Document var

uuid:String; var value:Stringdata-management-config.xml: : When I make a change to a DocumentPart, the
other client is updated successfully. When I set a breakpo...
I get this attempting to set the channel set on my data service. The

Some progress...I have made each object a Managed class with a
destination / assembler for each one. I configured one to many relations
for Document -> Chapter, Chapter -> Page. The create operation works as
expected. When the Document assembler is called, the Chapter and Page
assemblers have done their thing.I now working on getting Documents with
a fill operation. Its working, but I am still not clear on how to sync
changes across multiple clients. In an earlier small prototype, the way
I foun...
Looking at Tour de Flex - Managing Associations and Lazy Loading... The
source code for Product, Account, Contact, etc. would be nice, so I can
see how they are setup w/regard to handling the data services. I assume
these are all [Managed]? Is the whole example downloadable from
somewhere?
Ah. That certainly illuminates things a little better.I currently have a
single Assembler for Document and I have a hit a bit of a roadblock. I
can create the full object tree. Document has a Chapter and the Chapter
has a Page. But I want to edit the Page and sync any changes across
multiple clients. So I need an ItemReference for the Page. I turn around
a perform a getItem on the Page, but I get an error stating the item
must be [Managed]. The reason I don't have it managed is because LCDS
skip...
Hmm. I am not using Model driven. I hand-crafted everything including my
custom assembler. When I create a Document what is returned, of course,
is an ItemReference containing the created Document (the Managed class)
along with some sub-parts. What is puzzling is how to get ItemReferences
for all the sub-parts I want to change and have sync'd. I know I have to
invoke a createItem when something doesn't exist, but there is a lot of
getItem calls for any client interested in changes to any one
par...
I need help understanding the underlying LCDS mechanisms when a complex
object hierarchy is managed in LCDS. I have a custom Assembler because I
have specialized persistence requirements. My object hierarchy is
basically the following:Document Chapter Page TextDocument is the
[Managed] class. When a new Document is created, it is initialized with
a Chapter. Pages and Text are created when the document is edited. I
create new instance of Document and initialize it with an instance of
Chapter. On ...
My application needs server push. I am trying to get a simple "Hello

No luck, the same problem. The console message looks exactly the same.I
followed all of the above instructions except for the two optional
steps. I currently have no security considerations and I am not yet
using the JMSAdaptor.I am majorly stuck. I guess I can either switch to
the integrated Tomcat. Or, I can try my luck with JBoss. Any opinion on
which version of JBoss?
Looks like the missing class was the java transaction class, I thought
it was part of the error message. As soon as I solved that issue, I
might be down to my real problem. I can hope.[Flex]Received command:

I am much closer. Tomcat is putting some key messages in the console and
I overlooked them. It looks like I am closer than I thought. The request

Configuring Flex logging at least provided a start to figure out what is
wrong, but its still a bit obfuscated. It looks like a server problem. I
searched on the one line that looks appears to be the error message.

I still cannot get things to work. I have a very simple client sending
down a simple object via rtmp. I cut the services-config.xml and
data-management-config.xml files down to the bare essence of what I
think I need.The channel definition has the endpoint:
rtmp://{server.name}:2038. My data-management-config.xml sets this
channel as a default.My initial test in my Flex client is createItem.
The message seems to be sent to the server as far as I can tell by
looking at tcpmon. On the server, I ha...
There are five configuration files for LCDS: proxy-config.xml,
remoting-config.xml, messaging-config.xml, data-management-config.xml,
services-config.xml.I have searched for documentation that talks about
them in their entirety, but I cannot find anything satisfactory. I am
starting with my first application to learn this technology and Its hard
to tell which config files I must modify and which ones I can leave with
the default settings. I am using the data management services approach,
so I kn...
How exactly do you configure FlexBuilder to compile with theBlazeDS
config files. I have linked folder to the config files, butnot sure what
the mxmlc switch is for BlazeDS if that is how you doit?
