10.15 Web Application does not include Wizard Interface in all supported Languages
When executing your Web function application in different languages, the Wizard generated components do not execute consistently.
Solution
To run your Web function application in multiple languages, you must generate the appropriate components in the required languages. Generally, if you start by generating an interface in the default language, a component will always be found (it may not be in the correct language though). After you have created your default language interface, you only need to create separate menu components for each language as these are the only components which usually include text requiring translation (e.g. menu item descriptions).
Check that the default partition language where you are executing the Web function application is the same as the default partition language in the partition where the Wizard was executed. If they are different, use the Wizard to generate all the components in the default language of your target system.
