LiveCycle Data Services 3.1 offers these new features and improvements:
Alignment with Flex 4 and Flash Builder 4
The LiveCycle Data Services 3.1 supports the released versions of Flex 4 and Flash Builder 4.
Extensibility and increased flexibility for model-driven development
The ability to generate and customize model-driven application code is much improved in LiveCycle Data Services 3.1. In addition to generating and customizing client-side ActionScript code and model-driven forms, you can generate and customize server-side Java code. You can also extract and customize the code generation templates for the generated client-side and server-side code.
The Modeler provides new user interface features for code generation. You can choose the types of code to generate, which code generation templates to extract, and where to save the generated code and templates.
LiveCycle Data Services 3.1 provides major improvements in offline data management support, including:
Offline queries using SQLite in AIR clients
Encryption of local data in SQLite
Model-driven development
of offline applications
For more information, see "Occasionally connected clients" and "Model-driven applications" in Using LiveCycle Data Services.
Wider platform support
LiveCycle Data Services 3.1 provides support for additional platforms.
For more information, see the LiveCycle Data Services product page on the Adobe website.
Many fixed issues
About half of the LiveCycle Data Services 3.1 development resources went into fixing bugs and usability issues. See Fixed issues for details.
Known issues and API changes
If you encounter a Hibernate version conflict, you must configure the application server to load the Hibernate classes included with LiveCycle Data Services in the WEB-INF/lib/hibernate*.jar files of the lcds web application.
BLZ-494 - If client is subscribed to multiple destinations over a single polling endpoint and one subscription is invalidated, polling stops.
Data Management Service: The fix for LCDS-876 required a public Java API change. The DataMessage.setUpdateBody method has been renamed as DataMessage.modifyUpdateMessageBody.
FBR-134 - Model-driven development: Using the same entity backed by the same database table in multiple models is not supported.
FBR-317 - Model deployment: When deploying a model to the Model Assembler, you cannot have a an entity property named "id" that is not an identity property. This is due to a bug in the Hibernate libraries used in the Model Assembler persistence layer.
FBR-383 - Model-driven development: When working with RDS, certain types of action queries such as UPDATES or DELETES that result in 0 row counts and upon being successful cause RDS to throw this "RDS: java.sql.SQLException: General error resultset closed". This should be ignored. Also, all DDL statements cause this (for example, ALTER TABLE, etc.). Depending on the database driver used, you may not be allowed to execute queries. Again, the exception may be ignored and the statement will execute.
LCDS-864 - Model Assembler: After an authorization failure, local data change (delete) doesn't roll back if there is only one item in the collection.
LCDS-895 - Modeler: The Modeler does not preserve comments.
LCDS-907 - Modeler: Invalid entity creation: same table defined in multiple schemas creates duplicate fields in entity model.
LCDS-1022 - Model-driven development: Deleting an entity from a model does not delete its classes from its package.
LCDS-1076 - Modeler Expression Builder: Cannot use "up" and "down" keyboard arrow keys to scroll through the list of functions or the function categories.
LCDS-1103 - Model-driven form: Adding a model-driven form in Flash Builder design mode takes a long time and causes a flicker. This does not occur when using a Flex form, or if either type of form is added in source mode.
LCDS-1113 - Model-driven development: Import incorrect package for service when entity package and service package are different.
LCDS-1119 - Model-driven form: Using multiple model-driven forms in same application results in issues with unexpected interactions between the forms.
LCDS-1187 - Data Management Service: Data Management samples use a deprecated API. New versions of fill methods on the Assembler interface methods take a propertySpecifier as an argument, but the samples and a code sample in the documentation use a deprecated fill method defined on the AbstractAssembler class, which does not take a propertySpecifier as an argument: public Collection fill(List fillParameters).
LCDS-1445 - Model-driven form: Model-driven form created against an entity with a datatype column of type float causes rounding of that type based on the numericStepper's stepValue.
LCDS-1488 - Sample applications: The HTTPService sample in the LiveCycle Data Services samples application is not working on JBoss 5.0.
LCDS-1522 - The HTTP channels (HTTPChannel and SecureHTTPChannel) are not compatible with the small messages feature. For this reason we attempt to automatically disable small messages when the HTTP channels are being used. Due to this bug, there are some instances where small messages are not automatically disabled when using the HTTP channels and you could get errors unless you explicitly disable them. For this reason, when using an HTTP channel in your application you should explicitly disable small messages on your HTTP endpoint in the services-config.xml file.
LCDS-1533 - Edge Server: When using the Edge server to communicate with a JMS messaging destination in the application tier, if there is a problem on the JMS end such as the destination can't be found in JNDI, the error is not making it back to the client and the client could go into an endless reconnect loop. This would likely only occur due to a development or deployment time configuration problem but it is good to be aware of this issue if you are having problems using a JMS messaging destination through the Edge Server as it could make the underlying configuration issue more difficult to identify.
LCDS-1537 - Modeler: The Generate Code button in the Modeler generates code based on the saved model, not the in memory (possibly modified) model. It needs to prompt for save before running.
LCDS-1540 - Model-driven development: No error when table creation fails on deploy due to JDBC driver fail to load. RDS view does show an error for same issue.
LCDS-1564 - Client-side data management: autocommit doesn't work properly when the entity has a complex key with an association.
LCDS-1574 - Model-driven development: Using a DB2 database, the CLOB type length is limited to 255 when the column is created through model deployment. This is a bug in Hibernate. The workaround is to create the database table manually. See the following page for more information:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2969
LCDS-1578 - A null pointer exception can be thrown if there is a transient connection failure when using RTMP with LiveCycle Data Services in developer mode.
