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 y...

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 nest...

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 applicati...

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 wor...

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 laye...

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 t...

The following NullPointerException happens when I configuredestinations with bidirectional one-many associations more than onelevel deep. Example: Company, one-to-many Vendors, one-to-many ItemsItems, many-to-one VendorThe recursive subscription mechanism gets stuck in the Vendorassociation of Item ...

We really appreciate your reply. Your goal sounds very closeto what we have in mind. We operate in the SMB market. There are many levels ofprofitability and lack thereof which our customers cycle through asthey grow their businesses. It takes several iterations of thisbefore they become well establi...

I went into the category filters as you suggested, and turnedan immense number of them on. Now our stack trace is coming out. Wedid not realize that the category filters would override debuglogging being on. Thank you!

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 informatio...
