Internationalization

Internationalization is a central feature of the *FormEngine. During the initialization a Locale is assigned to a form instance that is used for any kind of output issues.

This contains particular:

• Label and tooltip of components
• Label of options in selection lists and trees
• Internationalized value formats for input and output (e.g. date)
• Error messages of validators and converters
• Confirmation messages before Submit
• Text generation of calculators
• Parameters for renderer

Within a form definition, there are various ways to label components or option internationalized. The common way is to declare MessageBundles for a form. It allows the use of the MessageBundles for the form definition as well as the use of various text keys. (e.g. <component ... label-key="select.label" info-key="select.info" > )

In small forms which should be used maybe only into two languages, it is also possible to enter the texts directly in the form definition. A component can be declared not only as an attribute also by sub elements with the required language.

<component ... >
   <label text="Label"/>   <!-- Default-Text -->
   <label lang="de" text="Beschriftung"/>

As a result the form definitions can be formed more compact, because all relevant contents are located in the XML file.
