RE: [flexcoders] LCDS / Hibernate - How tu update only one field (without sending all references)
You probably want to set the paged-updates=true flag on that association tag. This controls whether changes to collections are sent with the parent item or not. When this is true, if you modify that collection only the differences are sent. You can't do conflict detection in this mode as well. In 2.6.1 the best way to turn this option on is to either set: load-on-demand=true with lazy=false, or page-size=xx with lazy=true or false. These both turn on paged-updates automatically.

RE: [flexcoders] Can the Data Management Service detect database changes (not client changes) ?
Unfortunately there's no great way to do this automatically... DMS provides the DataServiceTransaction api which you can use to mirror any changes you make directly to the database but we do not have a hook to call these automatically in response to a database operation. The one approach I've heard of that works in some databases is to register a trigger in the database for that operation, then publish a JMS message in response to that trigger. Then in the LC DS process, you listen for that JMS message and use the DataServiceTransaction api to push that change out to the clients.

[flexcoders] FP 10 FileReference Security Cairngorm == Headache
FP 10 has thrown a curve for Cairngorm apps by requiring that FileReference.upload() and FileReference.download() methods be scoped within a user initiated action event handler. This requires substantial reworking of my app as I had previously implemented all my upload() and download() calls within Cairngorm business delegates. I was kind of hoping to work around this by creating my command class instances in the click event handler scope and therefore bypass this behavior without having to re-write a bunch of logic, but so far, no dice. It would be nice if the security implementation was smart enough to recognize that a series of nested function calls were within the scope of the UIA event handler. If there's a way to do that, I haven't come up with it. Any input appreciated. Jeff Battershall Application Architect Dow Jones Indexes [EMAIL PROTECTED] (609) 520-5637 (p) (484) 477-9900 (c)

RE: [flexcoders] Re: Flex DataService problem: unexpected unsubscribe and release collection
It is not so much a tool as just part of the HibernateAssembler in LCDS 2.6. In 2.5.1 you used to have to specify something like: destination id=support5.Account properties sourceflex.data.assemblers.HibernateAssembler/source scopeapplication/scope item-classsupport5.Account/item-class metadata identity property=id/ many-to-one property=consultant destination=support5.Consultant lazy=true / one-to-many property=accountContacts destination=support5.AccountContact read-only=true / one-to-many property=supportCases destination=support5.SupportCase read-only=true / one-to-many property=assets destination=support5.AccountAssetMatch read-only=true/ /metadata /properties /destination for each destination. Now, you just need to specify: destination id=support5.Account properties sourceflex.data.assemblers.HibernateAssembler/source scopeapplication/scope item-classsupport5.Account/item-class /properties /destination It also used to be the case that you needed to specify all destinations used by your flex app - even associated destinations. Now you just need to provide that configuration for destinations you directly access from the client (i.e. through a fill call or whatever). Any associated destinations needed by those top level destinations are created for you automatically. When the defaults for a particular association are not correct, you can specify just the associations you want to override in the metadata tag. If you want to take control entirely of the configuration for a particular destination, you just specify the identity tags yourself and we revert back to the 2.5.1 mode. Since the identity tag was required in 2.5.1 that also preserves the old behavior configurations in 2.5.1 work properly in 2.6 without change.

I think typically when you are using a managed association in LC DS you do not want to set any cascade operations like merge and persist. This is especially true in 2.5.1 where cascade=save-update (at least) caused problems when using managed associations. I am a little worried about the servlet filter which keeps the session open. I think for remote object that approach might work fine but for data management, it is opening and closing its own session so not sure how that would interact with your global session. One thing I noticed is that you have parent properties with lazy=false. That can be scary because it can end up pulling in a lot more of the model than you intend through that association. I usually recommend that parent always have lazy=true. Also, just to let you know the 2.6 beta is on labs.adobe.com and so you might want to give that a shot. It will generate the metadata section of the data-management-config.xml automatically from the hibernate configuration so that makes it easier to get started. In terms of the cascade settings, when you declare a managed association in LC DS for an association in hibernate, normally we do not require any cascade options enabled. I would like the assembler to not care if you do but unfortunately in 2.5.1 there is a bug when you set save-update (at least). I do have a fix for that problem but it did not make it into beta 2.

RE: [flexcoders] commitRequired returns true from DataService.fill()
As the fill response is being read from the server, data management is populating your value objects by calling the set methods. Most likely one of those is doing something that sends a property change event for some object which is already managed. The client debug log would probably provide the best clue - if you add mx:TraceTarget/ you'll see what is happening after the fill response is received. All PropertyChangeEvents that are received by the client are logged. We also log messages each time a new change is put into the log to be committed.The other clue is to look at what changes get committed when you do press commit - looking at the client or server debug logs for that would tell you which objects are being modified. A good rule of thumb is to not put too much logic into your set methods - particularly avoid things that have side effects.

Is there some reason your banners must be stored in .psd file? 2) Why are you focused on editing the .fla file and storing it in the DB?

What's a stored .fla file going to get you anyway? You still have to compile it. I would think that any solution that's going to work would be based around a data model and loading/manipulating data at runtime, not manipulating .psd and .fla files.

The other things I'd check are that your rpc.swc and fds.swc are of the right
version and match your server version. We added a small messages feature in
LCDS2.6 which uses Externalizable for messages to make the wrapper smaller.
That should be turned off by default for 2.5.1 clients but maybe something is
getting messed up there. You can turn this off via the
enable-small-messages=false flag in the channel's serialization properties
(see resources/config/services-config.xml for an example).

RE: [flexcoders] LCDS 2.6 and Hibernate - Does it work?
We did change from hibernate 3.1 to 3.2 in LCDS2.6 but otherwise I don't know of any compatibility problems introduced. We did that primarily so we could support the hibernate JPA annotations and there might have been a tweak or two to the hibernate assembler to get it to work in that environment. A good first step to diagnosing your problems would be to turn on the debug logging (in services-config.xml, set level=Debug and makes sure Service.*, Configuration and Message.* are in the patterns below).From those logs we can probably get a clue as to what is going on.

RE: [flexcoders] Re: Reusing HTTPService
I do like this approach - that's what I do when I code using AsyncTokens.
In the SDK's trunk depot, we have implemented a different way of using the
AsyncTokens which makes it easier to add per-call event listeners and result
objects particularly from MXML. It is in the class mx.rpc.CallResponder.
Here's a sample of how you'd use it:
mx:CallResponder id=myResponder result=optionalEventHandler(event)
fault=optionalFaultHandler(event)/
mx:Button click=myResponder.token = myService.getAllEmployees()/
mx:DataGrid dataProvider={myResponder.lastResult}/
Each CallResponder monitors a single AsyncToken at a time and propagates its
result and fault events to listeners on the call responder. It also stores the
lastResult property. This allows you to cache the previous result while the
next call is in progress. Any feedback folks have on this approach will be
appreciated.
I'll admit that modifying the token after the call was made is
counter-intuitive. It works because the AS VM cannot deliver any events on
that token until after the current executing code path has completed. We did
consider passing in the token as an argument to the async calls but didn't
think it really made things easier to understand and adds a risk that you'll
use the same token for two simultaneous calls.

Weird though how Flex requires one to add the responder after the call
is already made, don't you think? One would think the responder
should be in place before the call to service.send().

RE: [flexcoders] Re: Flex, Coldfusion, Air
Why would it 'fail'? - I'm not getting that. Like I said, it is basically a one-time hit, because the swf is going to be cached on the user's computer. It is certainly no more difficult than building and distributing an AIR app. Your use case for AIR should be based, IMO, on AIR's particular capabilities. Don't forget that your AIR app will probably require updating, which will result in more downloads for your users. Don't get me wrong, AIR is great and I'm using it for certain projects but don't get the idea that using it is going to completely solve your bandwidth problem.

RE: [flexcoders] Create Help System in Flex - how to display html in a canvas or component?
If your HTML rendering needs are rudimentary, you can use HTTPService to retrieve HTML files and use them for the htmlText property of the Text control. It supports (but not that well) such things as unordered lists, paragraphs and such. I've used this in combination with a vew stack and button bar to display multiple pages of help text. It's crude, but it works. Conceivably you could incorporate a Tree component and use that as a menuing system to retreive content via HTTP and display it in your content area.

Displaying full html in Flex (Flash Player) is not yet possible. What are your requirements? The simplest solution is to use a separate browser to display the html help pages. The Flex side needs to know where in the app the user is, and be able to determine the url to display. Using ExternalInterface you can exercise quite a bit of control over that window's behavior. Doing it all in Flex will be more difficult, primarily on the editing side. Dynamic display based on xml content is easy, but building a dynamic layout that looks like a help system might be a bit tricky.

RE: [flexcoders] ComboBox in Component won't open to Saved Value
The Combobox by itself does not really support what you're trying to do.
As Tracy said there is sample code you can draw on to extend the
ComboBox to accept a 'selectedValue' parameter or something of the sort,
which in turn will fire internal logic to determine which item in the
dataProvider matches and to set the selectedIndex accordingly.
The other part of this is using binding. To have your instantiated
combobox to update its selectedIndex when a value changes you need to
reference a bindable value. If another code alters that value, it will
then re-fire the internal logic in your custom ComboBox.
{Bindable]
private var dp:Array =
[{data:'foo',label:'foo'},{data:'foo1',label:'foo1'},{data:'foo2',label:
'foo2'}];
[Bindable]
private var myVal:String = foo;
local:CustomComboBox dataProvider={dp} selectedValue={myVal}/

RE: RE[flexcoders] S: LCDS - how can I improve the createItem function?
So if you have all 1000 in the same batch, it should essentially just be processing 1000 insert statements. While that is happening, your commit call is still outstanding - i.e. it has not yet received the response back.You could pretty easily add a result handler for that commit operation so your user knows when it is finished (i.e. set up a busy cursor when the commit occurs and remove it when the commit result/fault comes back). I guess the other question is whether there is a more efficient way to insert all of those 1000 items. LC DS will add some overhead onto that process of creating those items but I would not think it would be a ton more than just the overhead of running 1000 insert statements. It would certainly be possible to create all 1000 items on the server using a remote object call, then use the DataServiceTransaction.createItem call to notify the data management system (and the flex client) that they are all there. It's not clear though that this would be more efficient. Note too that the LC DS debug logging is pretty expensive so if you turn that off, it will speed up the server a lot.

RE: [flexcoders] Re: LCDS: Debug RTMP Traffic
Yeah, it looks like somehow you are getting a DataService trying to use a DirectHTTPChannel.That only works for for HTTPService, and WebService. DataService needs a channelSet which supports AMF (AMFChannel, or RTMPChannel). I'm confused how you are getting into this situation though... those get created on the client via the endpoint property on some services or you can define one explicitly in ActionScript or MXML.Can you show how this tasks destination is getting defined in ActionScript? How is its channelSet specified - on the client via the channelSet property or on the server? If it is on the server, make sure you are compiling against the services-config.mxml file (it is a project/compiler option).

Can you check if it works if you comment out the cacheId setting?Since the offline feature also persists configuration, it might be that it has cached something invalid. If it works, you might try removing your shared objects (for flash) and sql-lite database files (for air) If you could also send me the entire flashlog.txt - (probably offlist - [EMAIL PROTECTED] since it is can be big) I'll see if I can track down what is going on. I thing that is helpful to debug config problems is to look at the value of the variable mx.messaging.config.ServletConfig.xml - it is the information which is compiled into the SWF. In this case, I'd expect to see the default channels for the RTMP channel and then the destination info.

I have a similar problem and have tried to follow your advice.

How can you make the Flash Player wait for these events before adding the page endered with the images correctly loaded?

RE: [flexcoders] Flex CF Gateway Integration with CF 7.02 - What Am I Doing Wrong?
When examining CF8's jar files vs. CF 7.02's, CF8 has a jar file ccfgatewayadapter.jar.

Re: [flexcoders] Re: Flex SDK 3.1 changes to WebServices breaking existing services...
Todd,
This is the exact same problem that I described in
http://tech.groups.yahoo.com/group/flexcoders/message/122930 . We can't
implement the fix that you mention, because you'll find that your server-side
now outputs:
paymentAccountsfooA/paymentAccounts
paymentAccountsfooB/paymentAccounts
paymentAccountsfooC/paymentAccounts
instead of
paymentAccounts
paymentAccountfooA/paymentAccount
paymentAccountfooB/paymentAccount
paymentAccountfooC/paymentAccount
/paymentAccounts
which in our scenario breaks our existing non-Flex consumers.
If you remove the property definiton for PaymentAccounts in FooDogVO, you'll
find the 3.1 decoder will create it properly (as an ArrayCollection). In our
case, we couldn't do that either, because our PaymentAccounts is a subclass of
ArrayCollection. But it'd work for you. The fact that the decoder decodes it
two different ways depending on whether the ArrayCollection is predeclared is
probably a good indicator that its a Flex bug.
-Jeff
On Thu, 04 Sep 2008 00:45:55 -, Todd wrote
I've sort of figured out new WSDL syntax that works as expected.
If I change the WSDL declaration of paymentAccounts from:
xsd:element maxOccurs=1 minOccurs=0 name=paymentAccounts
xsd:complexType
xsd:sequence
xsd:element maxOccurs=unbounded minOccurs=0
name=paymentAccount type=FooDogType/
/xsd:sequence
/xsd:complexType
/xsd:element
TO:
xsd:element maxOccurs=unbounded minOccurs=0
name=paymentAccounts type=FooDogVO /
It all seems to work. This gets rid of some nested complexTypes and
sequence.
However, my bigger concern is changing all this code that worked
perfectly in 3.0 (10 services, 20 calls per service) and was probably
a workaround to make it work in 3.0.. What it does for the stability
of our code base.
It seems that the backward compatibility of Flex and Web Services is
a bit sketchy, at best...especially because I don't know of other
situations that will need to be changed, too. (This could be the
first of other problems that I've unleashed.)

Additional info - the blank pages are occuring primarily when printing to Adobe Acrobat 8.0 driver (ironically enough).

RE: [flexcoders] Flex RemoteObject and Browser cookies
If you are using HTTP-based channels, all of the cookies set by the server should be returned to the client via the RemoteObject calls. Since you are seeing the jsessionid, it sounds like you are using HTTP based channels. If all cookies are not making it to the server, it may be because you are using two different cookie domains in your application. As part of the set-cookie header, you can specify additional information which broadens or narrows the scope of the cookie's setting. If you can sniff out the headers for the set-cookie operation using an HTTP traffic sniffer or logging on the server, you might see a difference in how these cookies are being set or in how the URLs are formatted going to the server. Any difference in the server-name or port specification can alter the cookie domain/handling - i.e. even http://foo.com and http://foo.com:80 may be treated as different cookie domains. Definitely watch out for localhost versus myserver.com as that is a common way to switch cookie domains too.

Is it possible to bind an ArrayCOllection to an array, like so
public var summDataForControllers:Array = new Array;
public var _summDataForContrAC:ArrayCollection = new
ArrayCollection({summDataForControllers});
I have a modelLocator that contains these to items (above) and I want a
component to bind to the arrayCollection. I am storing the information
in the array first because when I try to update the arraycollection from
my component and then access a certain item in the arraycollection I get
Index 0 out of bounds. So in other words I iterate and say
arrayCollection.addItemAt(i) then try
arrayCOllection.getItemAt(i) I get the out of bounds issue.
But if I iterate and store the information in an array everything is
fine, but now my component can't listen for updates, which is the reason
I am trying to bind my arraycollection to the array.
Thanks in advance for any help.

RE: [flexcoders] the commit method of LCDS doesn't commit deleted child object. Is this normal?
When you remove an item from an association property, if you want to delete that object you do have to call deleteItem explicitly.Currently removing the object from the association property will only send an update change to the parent object. It won't delete the child object. Many O/R systems have a cascade=delete attribute on the association which lets you do the delete automatically when the child becomes disassociated but we haven't implemented this feature in LC DS yet. This is independent of autoCommit... even if you set autoCommi=true, you'll still need to do the deleteItem explicitly.

What exactly is happening in 3.1 that's not happening in 3.0? Without posting
the real code where the VOs aren't what you've shown here it's kinda hard
to help, so I've gotta ask more questions :) Also how are you invoking the
service, and what code are you using to map the xsd types to your classes?
What is actually happening is an array of strings is now being created as an
array that has one element of type ArrayCollection. That nested array is the
array of strings. The detailed description of what was happening is way at the
bottom of my original post. The service is invoked via mx.rpc.soap.WebService
by calling service.operation(Request) . The xsd types are being mapped via
this mechanism:
SchemaTypeRegistry.getInstance().registerClass(new
QName(http://www.harte-hanks.com/hhl-User/,UserType;),UserType);
I'm pretty familiar with Flex's SOAP encoder/decoder by now, so I can
probably help, and also if there's a bug in 3.1 I wanna know about it so I
can fix it :)
Thanks for your help. I've been reading this forum for probably a year and

I wonder if maybe the client is writing either a lot of data into a large message or if it is introducing some latency with its ability to write? It might make sense to turn on more debugging options such as Protocol.* or maybe even * so we see all targets. That will give us more fine-grained timings of where the time is being spent. Of course that much debug logging will slow things down overall but it can be helpful to see what exactly the system is doing. Jeff From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Rogier Oorburg Sent: Tuesday, August 19, 2008 2:04 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] LCDS and real-time performance Hi, Recently we have started an experiment on our benchmark-LAN where we have several Windows XP PCs running test programs. One of the PCs is the data-injector (Flex) which pushes changes every second, one is the LCDS2.6 server running on Tomcat and one PC is running the client application (Flex) in which the changes are visible every second. This experiment should determine if Flex using LCDS is a viable option for our real-time systems. There is very little network-traffic and CPU-usage on all PCs is very low, yet the system is able to handle only 400 changes every second. Using our own logger we see that about 400ms pass between the injector committing the changes and the server synchronizing the database. Another 400ms are needed to get all the changes to the other client so it can merge the changes and display them. By examining the built-in server-side logging of LCDS, it becomes clear that a lot of time is spent in the sending and receiving of messages over RTMP: [LCDS] 16:25:10.578 [DEBUG] Thread[my-rtmp-SocketServer-WorkerThread- 1,5,main] Connection '19658898' starting a read. ...

[LCDS] 16:25:11.421 [DEBUG] After invoke service: data-service reply: Flex Message (flex.messaging.messages.AcknowledgeMessage) ... etc. etc. As you can probably see the communication starting at the first entry up to the start of deserialization already takes approx. 400ms.. the processing of all the changes 172. The pushing of all the changes again takes about 400ms. If we can eliminate these two bottlenecks LCDS would be the perfect candidate to use in our new systems. We have tried everything we can think of, but nothing seems to help. Is it the RTMP protocol or a server or socket setting, or the way the server handles multithreading? Is there some JVM setting we don't know about? Any pointers and help would be appreciated! Greetings, Rogier Oorburg inline: image001.jpginline: image002.jpg
RE: [flexcoders] Re: LCDS 2.6 + Hibernate: problem deleting items
If you could send me the server debug log with Message.* and Service.* enable I could tell what is happening. I've seen this type of behavior in the past, but only when some query or something was holding onto a cached copy of the deleted item. After the item gets deleted, we could be refreshing a query or something and then seeing that cached item and thinking it needs to get added back to the collection. If I recall correctly though, you are using the hibernate assembler which shouldn't be caching queries - unless maybe you have turned on the cached queries option or maybe have customized the assembler? Another possibility is that you might have a bi-directional association involving this item and you are not removing the item from both sides of the relationship.

RE: [flexcoders] Difference between specifying remoteObject in mxml and in actionscript ?
I think the problem here is that mx.rpc.remoting.RemoteObject does not support
the endpoint property whereas mx.rpc.remoting.mxml.RemoteObject does. I
believe endpoint was originally intended just to be a simple alternative to
defining the ChannelSet and so not supported universally but we are thinking of
just moving endpoint up to the base RemoteObject tag since it is so commonly
used.
If you use the mxml variant from AS you'll also need to use the mxml operation.
The other option is to just add this chunk of code to your AS version and
avoid use of the endpoint property:
/**
[EMAIL PROTECTED]
*/
mx_internal function initEndpoint():void
{
if (endpoint != null)
{
var chan:Channel;
if (endpoint.indexOf(https) == 0)
{
chan = new SecureAMFChannel(null, endpoint);
}
else
{
chan = new AMFChannel(null, endpoint);
}
channelSet = new ChannelSet();
channelSet.addChannel(chan);
}
}

Subject: [flexcoders] Difference between specifying remoteObject in mxml and in
actionscript ?
I'm sure I'm missing something here, but It would be good if anyone
could point out exactly what it is!
I'm attempting to configure a remoteObject *without* the compiler option
of -services \\someServer\Path\WEB-INF\flex\services-config.xml or
similar
I initally thought it would be a question of merely specifying an
endpoint, so I started off with this in my actionscript class :
_remoteObj = new RemoteObject();
_remoteObj.makeObjectsBindable = true;
_remoteObj.destination = fluorine;
_remoteObj.source = ppRemoteService;
// add the endpoint, all the code above works fine with the compiler -
services option
_remoteObj.endpoint = http://localhost/ppBackend/Gateway.aspx;;
Which errors out at runtime with :
Cannot assign operations into an RPC Service (endpoint)
Yet, if I define the service in my main Application mxml in what looks
to me like identical parameters , like this :
mx:RemoteObject id=testRemoteMxml
makeObjectsBindable=true
destination=fluorine
source=ppRemoteService
endpoint=http://localhost/ppBackend/Gateway.aspx; /
then just use _remoteObj = Application.application.testRemoteMxml into
my actionScript class (apologies for bad form there)
it works just fine.
This is in flexbuilder 3.0 with the default Flex 3 SDK, I should
mention.
So what am I missing? A timing / initialisation error would be my first
thought, but if so then I can't see quite how.
I'm probably just being a bit stupid, anyone got any ideas or relevant
experience?
Many thanks,
Jim.
(p.s. I notice that there is no autocomplete suggestion in flexbuilder
for remoteObjectInstance.endpoint in actionScript yet it compiles fine.
This is probably a clue that I'm doing something wrong, I would say. If
only I knew what it was!)

RE: [flexcoders] Re: LCDS: how to fetch the items from lazy collection
We've been wanting to add a prefetchAndExecute type of utility which would
make this a little easier. I think what you are doing is good though it would
be a bit more efficient to just call:
arrayCollection.getItemAt(0, arrayCollection.length)
That second parameter is the prefetch parameter which specifies the number of
items to fetch. That one call with thrown an IPE if all items are not resident.
The advantage of doing this all at once is that we can make one big request to
the server instead of fetching each page independently.

Subject: [flexcoders] Re: LCDS: how to fetch the items from lazy collection
In fact I do not have any backend code in my project - I use the
Hibernate Assembler from LCDS to supply data (DTOs) into my flex
client. My lazy ArrayCollection is partly fetched from the server -
just the items needed for display. Now when I want to export all items
into file, I need to fetch all the remaining items into this
collection. So I am looking for some simpler solution to do this.

application it loses the ability to runtime fetch the lazy collection
from the database (because you are already on the client machine, not

Just make sure whatever you send through LCDS over the wire is not
lazily loaded. So load all collection explicitly with hibernate before
you send them. Or better yet don't send hibernate objects of the wire
at all, create DTO (Data Transfer Objects; search for DTO design
pattern) objects instead. Load everything you need in your flex

RE: [flexcoders] Re: DataServiceException
Yeah, it should be calling any fill methods which are still actively managed by
clients in that refreshFill call - as long as you have autoSync=true. There
are a couple of ways to track this down:
1) Put in this printSeq.jsp file (enclosed below) and request it. It will
show you all active fills, etc. If that is empty, somehow the client's fill is
not auto-sync'd.
2) If you turn on the Service.* debug target it should at least indicate
which fills it is trying to refresh.

RE: [flexcoders] How do you auto-refresh LCDS?
When the autoSyncEnabled property of the DataService is true, the other
client should be pushed the deleteItem message automatically if they have a
managed copy of that item you are deleting.This does require that they both
be using some type of channel which supports push (i.e. RTMP or polling).
When you remove an item from a collection, it is automatically removed from all
fills which contained that collection and those changes are pushed to any
clients that are currently managing those fills.
If you turn on the Message.* debug logging target on the server, you can see
each message sent by the client and it contains messages for each client that
is being routed a given message.
The autoRefresh setting is separate from autoSync (though requires that
autoSyncEnabled be set to true). AutoRefresh controls how the membership of
filled collections is updated after an updateItem or createItem operation.
The default is to re-execute the query once for each transaction that contains
an update or create. The old and new results are compared and any changes are
pushed out to subscribed clients.
If you initiate a change on the server, you can notify clients of these changes
but you have to use the DataServiceTransaction api to do so. One of its
methods is refreshFill which you can use to update a query. In 2.5.1 that
would only detect when items have been added or removed from the collection.
In 2.6, there is an option now to look for property changes made to items as
well.

Subject: [flexcoders] How do you auto-refresh LCDS?
I'm not sure how you refresh clients when there's a change on the
server. After I perform a _ds.fill(), the user can delete 1+ of the
items from the managed collection. The ActionScript looks like:
private function deleteItems():void
{
var selectedTasks:Array = taskList.getSelectedTasks();
for each (var task:ExploitationTaskVO in selectedTasks)
{
_ds.deleteItem(task);
}
// Commit the deletes to the server if needed
if (__ds.commitRequired)
{
__ds.commit();
}
}
_ds.commit() has to be called to propagate changes to the server
because I have _ds.autoCommit = false.
The LCDS JavaDocs state that changes from a createItem() or
updateItem() call will propigate to all clients if auto-refresh=true.
Is that true for deleteItem() calls too? And where is this
auto-refresh property? I don't see it under Java AbstractAssembler or
ActionScript DataService classes.
Also, what if I create, update, or delete a task on the server without
doing it through the DataService(like through a java delegate). Can I
force the DataService to refresh it's clients on the java side? Is
this what the DataServiceTransaction.refreshFill() method is for?
Thanks,
Geoff

RE: [flexcoders] LCDS : updateItem method
Updates are tracked automatically as you change properties on your item. If you have autoCommit turned on, each property change of a managed object will automatically send the changes to the server and call updateItem. If you turn autoCommit=false, you can call dataService.commit() to commit all pending changes or dataService.commit([myObject]) to commit just the changes for a specific object.

This error can occur when you access an unpaged item when paging is enabled of
course, but given that you are running that code in the result handler it seems
like this is not the problem (unless the result event is being delivered for
another call on that data service).
It might also happen if the identities are not getting defined properly in

RE: [flexcoders] Re: LCDS data synchronisation problem
Hi Florence, Thanks for sending that along... we are missing a clear error message for whatever your problem is - sorry about that. I have tried a few things here to try and get that exact error and can't seem to reproduce it here myself either. There are two ways to get configuration into the Flex client. You can either compile your Flex app directly against the services-config.xml file and it will compile in a subset of the server's configuration into the player, or if you define a ChannelSet on the client you can download the config at runtime after the client connects. It appears that you are getting the configuration at runtime, not compile time so probably if you set the option to compile against services-config.xml this will either start working or at least give you a clearer error message about some configuration that is missing for the insync destination (using the command line compiler, it is the -services option, or it is settable as a project option in flex builder). From the logs you sent, I see it connecting successfully but it looks like it is getting an empty definition of the insync destination - i.e. no properties, no metadata and no identity attribute all of which would be required for a valid DMS destination. You can see exactly what XML the client gets by looking at the variable: Import mx.messaging.config.ServerConfig trace(ServerConfig.xml); We use that variable both to store any compiled in destinations as well as to populate destinations after connect time so doing that trace before and after you get the error would tell me exactly what the client is seeing for that destination. I suspect insync is maybe getting put in there but without a propertiesmetadataidentity name=foo/metadata/properties construct. Another possible thing that could cause this is that there is an error initializing that destination on the server at startup. To check on that possibility, make sure to check your server's logs for errors and possibly add Message.* and Service.* targets to the services-config.xml's logging section and set level=Debug there to get more info. Sorry for the difficulties getting this working. Please let me know if you do find the problem so I can improve our error messages.

RE: [flexcoders] Re: LCDS paging exception

RE: [flexcoders] LCDS - Data Management Service Problem
This error can occur when you access an unpaged item when paging is enabled of
course, but given that you are running that code in the result handler it seems
like this is not the problem (unless the result event is being delivered for
another call on that data service).
It might also happen if the identities are not getting defined properly in
ActionScript. If you add mx:TraceTarget/ and send along the resulting
flashlog.txt, we can see what is happening from that.

Hello,
I have a Data Management Service that uses a managed ArrayCollection of users.
When a user is added by one client, the other clients are notified by the Data
Management Service, and I want
to loop through the ArrayCollection, using the code below, but I always get the
following error :
Error: Item requested is not available. A request for the item is now pending.

This error occurs when the line users.getItemAt(j) as User is executed.
It seems that although the length of the ArrayCollection users equals 1, I can
not get the Item at position 0. Maybe the update of the ArrayCollection
is not yet finished ? How can I loop through the ArrayCollection upon changes ?

RE: [flexcoders] Only last row shown from dataservice result (Hibernate+LCDS)
It sounds like you have a complex identity object – i.e. not a set of primitive properties. Try adding a toString() method in your identity class which returns a unique string for each instance.

RE: [flexcoders] LCDS Memory Usage
That is basically how it works but only if you have auto-sync enabled=true and cache-items=true on your destination settings. The auto-sync feature requires that we maintain at least the identities of all objects managed on every client so that we know where to push changes. The goal here is that you don't have to worry about tracking that and can still easily keep clients in sync. Also, if two clients fetch an object with the same id, only one copy is cached. If you turn cache-items=false, we cache only the ids, not the items so we keep a lot less state around (though we do have to go back to the assembler more often so that is more load on the database). If you turn auto-sync off, the server maintains no state but the synchronization functionality would then only work if you enable manual sync - i.e. where your clients specify subscriptions they want to listen to and also can specify meta-data that is attached to all changes made. That meta-data is used to route changes to the right subscribed clients. Jeff From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Geoffrey Sent: Wednesday, July 23, 2008 5:21 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] LCDS Memory Usage Looking in the LiveCycle Data Services ES Developer's Guide, page 190, it states: By default, the Data Management Service caches items returned from fill() and getItem() calls and uses cached items to implement paging and to build object graphs on the server when implementing lazy associations. This causes a complete copy of the managed state of all active clients to be kept in each server's memory. Here's what I think that means. If I have 100 clients, and each client has one managed collection that contains 100 items in it, then there would be 10,000 copies residing in memory on the server(100 objects for 100 users). Am I understanding this correctly? Does this seem inefficient? What if those objects happened to be really big objects... I mean really big. Seems like that would take up a lot of memory on the server. Has anyone come up against this in practice? Thanks, Geoff inline: image001.jpginline: image002.jpg

RE: [flexcoders] Re: DataService gives CollectionEvents for each item when committing one item
Probably what you need is to just turn off auto refresh for that fill. Just
override autoRefresh(List params) to return false.
Since LC DS does not know what each particular query is doing, it will refresh
each query after performing an insert or update. It is looking to see if
items have been added, removed or re-ordered based on the properties you
change. In your case, maybe the query results are coming back in a completely
different order so LC DS would be trying to update the order. It might also be
that your equals/hashCode methods of your server side VOs are not defined
properly so after it does the auto-refresh it thinks the items are completely
different from the way they were originally.
Turning on the server side debug logs for the Message.* and Service.* targets
would give you a good idea of what is happening on the server.

RE: [flexcoders] LCDS and Hibernate - how to setup bidirectional relationship
You do not have cascade delete set in hibernate do you? I don’t think LC DS would delete items if you are just removing an item from a collection or set an association to null. In general, just calling “deleteItem” on the child should remove it from the parent’s child property automatically. If you are not running on the latest hotfix it might be worth trying that as there have been a few bugs fixed in that version. I’ll send you a copy off list.

A renderer in the dropdown doesn't have any clue it is working for a combobox and you just have to wire it up correctly. Personally, I'm not a fan of using bubbling to pass events. IMHO, bubbling is designed for cases where you cannot know the relationship (something internal got clicked, scrolled or added). Everything else should be handled without bubbling. The CB listens for events from the dropdown already. If I were doing custom work, any additional event would be dispatched from the dropdown and listened to from the CB.
