This thread was started by hchafi to discuss using theHibernateAdapter to reach the goal of using Hibernate Annotations.I introduced a different approach to achieve the same goal byAVOIDING the HibernateAdapter (becuase it only supports CRUDmethods and requires 100% of your business logic to be written inactionscript on the client).bjk0002, I am not sure which method you are truly interestedin. For my approach, the documentation is out there. I wouldsuggest your starting point be reading the Jav...

We have the JBoss implementation of EJB 3.0 working withFlex. The JBoss implementation of EJB 3.0 is really hibernateannotations... In this configuration, Flex does not need to talkdirectly to Hibernate, and we have the full power of the new EJB3.0 Annotations (beyond the support and features provided in theHibernateAdapter). Our Assemblers use JNDI to access session beanswhich work with the entity beans.One huge problem with Flex however is that due to therelationships between objects in the OR...

When the JavaAdapter calls an updateItem Assembler method, anArrays.ArrayList passed in as the changes parameter. This is animmutable object list. This means I can not change more objectproperties on the server side, add the property names to the list,and get the client in sync. I can do this effectively if I use a sync method and theChangeObject system, which maintains a String[] for the list ofchanged properties. Please bring the JavaAdapter up to date withthis functionality. It is very import...

It appears that DataService is not handling theUpdateCollectionMessage correctly when updateMode = server_update,and the DataService autoCommit = false. Our application first calls DataService.createItem, then ourAssembler returns APPEND_TO_FILL on the refreshFill method call. Wesee the UpdateCollectionMessage being dispatched, but nothinghappens to the collection on the client.NOTE: If we change nothing in our application exceptautoCommit = true, then everything works correctly.

I just noticed a property of AbstractAssembler which willhelp with this significantly - the destionationId is populated oneach call to the Assembler, which is great!

We are writing a framework around the AbstractAssemblerinterface. However, we need to throw different database exceptionsso the client can get a decent error message about what went wrong.This was not a problem when writing sync functions because theywere not tied to a specific interface. When we extendAbstractAssembler, the compiler does not let us implement methodswhich throw any exceptions. There should be a mechanism for sendingan intelligent error message from the server back to theclient.

We use a common base class to handle most Assembler functionswithout writing a separate DAO class for each destination. The onlytrouble we have in this design is using the API functions inAbstractAssembler which give no reference whatsoever to the Classof object to act on. One such function is getItem(Map). The Maponly contains id information, with no reference to what kind ofobject to retreive. If the destination string was included, or aClass object, we could get any record in the system by wr...

I thought that the AsyncToken was always supposed to beavailable in the ResultEvent?After a call to createItem (on a DataService), the token dataI set is not in the token property of the event when theResultEvent function executes. The result is an AcknowledgeMessage.But in the debug environment, I do see a dynamic objectcalled __token_chain__ below the outermost token. Beneath it is aUID, and below that is the token I'm looking for - the one whichcontains the true result of my original call, in...

I spent considerable time last year documenting this conceptfor the people at Hibernate, in an attempt to show them clearly howthe library needs enhancement to accomodate this scenario, andvolunteered to develop the patch. They refused to accept thechanges at the highest levels of the team.I think you realize we are not using the hibernate assembler,but EJB3.0 through the java adapter, so the changes made to thehibernate assembler would not effect our application...The cat's meow would be for Fl...

Our Java naturally classes contain properties which arerelationships to other classes - either one to many or many to one.Due to the fact that these relationships are so intertwined, manygiven objects end up referencing a large portion of the database ifone were to recursively follow all of the nested relationships. Assuch, we desire to have the option of not loading certainrelationships when the data is not needed.We use EJB 3.0 (JBoss implementation using Hibernate) forobject persistence. It a...

Even with one-level bidirectional associations, FDS evenuallyloops forever when enough records are in the database, and neverresponds to the fill request. I have had to remove all of mymany-to-one entries from metadata when they point back to theowning entity in order to keep working on my application.

The final aspects of the associated data set is filtering andsortation (client defined but server performed). I see support within the Flash AS component library for theseconcepts but they are problems that really need to be solved on theserver side. Client side sorting and filtering only really workwith small datasets (not found often in the enterprise).Do you know if FDS will conquer client-defined, serverperformed sorting and filtering?

Thank you very much for the information. We deal with many tables with thousands, tens or evenhundreds of thousands of records in which case means returning allof the results is not possible, even back to FDS in response to afill request - let alone to a client over the network. How does theDAO layer need to respond to a fill request for a destination whichis paged? Can lazy associations still be paged?When you mention caching, it reminds me of another aspect ofconcern to us - stale data. Someti...

I have written EJB's which receive and process ChangeObjectin response to the sync method call. Class version erros likeClassNotFoundException and ClassCastException are created whenapplications written to receive ChangeObject are not running in thesame web application as Flex (and thus created by the sameclassloader). I have tried moving the jar file to a global area soa parent classloader would take over, but this causes new problemsfor the Flex framework.I have found a clever way to configure...

FDS when set up for debug logging can crash the JVM withOutOfMemory exception while sending output to console. It beginseating hundreds of megs until in my case about 1GB of memory is thelimit. Turning off debug solved my immediate problem of the crashbut I can no longer watch the flow of information.Is this where we post bug reports?

If some of an AS object's properties are not bound to a panelcontrol, Flash Player inserts random data in the rest of theproperties, which are then sent to the FDS server.

There are stack traces we need to see when FDS makes calls toour Assembly functions. At the moment we have all of the logsettings we can find in the XML configuration files turned on. FDSstill swallows all of our exceptions without a stack trace. Anyinformation about the location of additional log settings would beappreciated.

Page 1085 of the 1240 page Application Development manualdiscusses configuring data services. AMFPHP is a clone of Flash Remoting. Flash Remoting is notthe same as FDS, and FDS is not a drop-in replacement.In short, Flash Remoting only manages function calls tovarious server-side programs, and you do the rest. FDS does notsupport certain Flash Remoting functionality, but provides manyother features which are way beyond the scope of Flash Remotingsuch as RTMP, publish/subscribe messaging, conflic...

We understand that FDS supports lazy associations, but thedocumentation is unclear about whether it's necessary and in whatmanner to partially initialize an array which is not empty but inthe "lazy" state, as opposed to the fully initialized state, andthe empty state.We are using the Java adapter, so our application isresponsible for how data comes out of the DAO layer.Any information would be appreciated - thank you.

I am evaluating Flex, after having been accustomed to FlashRemoting. We are used to Flash remoting being able to make calls toEJB's via JNDI. Adobe, please include JNDI support in the nextrelease of FDS so we can reuse our existing middle tier softwareand avoid writing another layer just to translate between onemethod call and another. Thank you for your consideration.
