Info

The information you enter in this panel is stored in a resource bundle for the entity object. This means that if you want to translate your application, you have to go through numerous resource bundles, created for all your entity and view objects (which also support control hints) and make language-specific copies of all those bundles. Internationalizing Control Hints. Explained in ADF Developers Guide. http://download.oracle.com/docs/html/B25947_01/bcentities005.htm#sm01 40 This can be a tedious job when you have many ADF Business Components. When using JHeadstart, you have an easier and faster alternative. By default, JHeadstart will copy the values for Label Text, and Tooltip Text to the corresponding item properties (Prompt in Form Layout and Hint Text) in the JHeadstart Application Definition file. Then, when you generate your application with the servicelevel property Generate NLS-enabled prompts and tabs checked, all translatable strings, including labels and tooltip/hint texts, are stored in one centralized resource bundle, or database table. One centralized bundle is much easier to manage and translate, and when you use the database table as the store for translatable strings, JHeadstart even offers an in-page editor to translate your application. See chapter 11 ”Internationalization” for more information. Now, if for whatever reason you want to use the business component resource bundles for translating labels and tool tips, instead of the JHeadstart resource bundle or database table, then you can do so by switching a JHeadstart preference. Go to the JDeveloper Tools menu and choose “Preferences…” At the left side click “ JHeadstart Settings” and the panel displayed below appears. If you check the checkbox “Bind Item prompt to ADF BC Control Hint “Label Text”, JHeadstart will no longer copy the Label value over to the Application Definition. Instead, it will set the Label property of the item to an EL expression that references the label as defined in the Control Hints panel. 3 - 10 Creating Business Components JHeadstart Developer's Guide
3.2.6. Implementing Business Rules ADF Business Components has extensive support for implementing business rules, both declaratively using so-called validators, as well programmatically in the Entity Object implementation classes. The JHeadstart Team has written a comprehensive white paper on implementing business rules in ADF Business Components. This white paper can be downloaded from OTN, and includes a classification of business rules, and a structured approach to implementing each type of business rule. Implementing Business Rules in ADF BC. White paper on OTN. http://www.oracle.com/technology/products/jdev/collateral/papers/1013 1/businessrulesinadfbctechnicalwp.pdf 3.2.6.1. Adding Business Rules to the beforeCommit() method If your business rule logic in the entity object beforeCommit() method can throw an exception you must set the jbo.txn.handleafterpostexc property to true in your application module configuration. By doing so the framework automatically handles rolling back the in memory state of the other entity objects that may have already successfully posted to the database (but not yet been committed) during the current commit cycle. However, there is a known issue (bug 4606787) which causes the jbo.txn.handleafterpostexc = true setting to conflict with custom activation/passivations of the ADF Business Components state. When such a conflict occurs, the following exception will be thrown: JBO-25033: Activating state from Database at id xx failed. JHeadstart uses custom activation/passivation in the JhsPageLifecycle class to restore rows already removed from ADF Business Components when the final database commit fails because of referential integrity constraint violations. This means you cannot set jbo.txn.handleafterpostexc to true, and if you nevertheless do so, you will get the JBO-25033 error. Fortunately, JHeadstart provides functionality to work around this bug. Instead of setting the jbo.txn.handleafterpostexc property to true, you need to check the group-level checkbox Always Passivate State Before Commit? in the Application Definition Editor. Note that this setting is only visible in expert mode. JHeadstart Developer's Guide Creating ADF Business Components 3 - 11
