Internationalizing business objects

Make fields multilingual – mark String attributes, language table and disabling.

HOW-TO DEVELOPER UPDATED: JUL 2026 APPLIES TO NUCLOS 4.2026.X

On this page

In Nuclos not whole business objects but individual fields are internationalized. A BO counts as internationalized as soon as at least one field is declared multilingual.

Language table

For an internationalized BO Nuclos creates a dedicated language table and joins it with the BO table at runtime – depending on the data language chosen at login, the matching content is always shown.

Making an attribute multilingual

Path: Configuration → Business object. Only String data types can be internationalized:

Data type	Java type
Text	java.lang.String
Memo	java.lang.String
Text (large object)	java.lang.String

Tick the multilingual checkbox. Only fields marked this way go into the language table.

Disabling

If the flag is removed later, the field and its content are deleted from the language table – only the primary language values remain in the BO table.
