Mendix AttributeLock

Mendix AttributeLock is a Java action that helps enforce control over attribute and association changes by verifying if modifications are allowed before committing them.

• None

• Validate if attribute or association changes are permitted before committing.

1. Add the Java Action: Place the Java action in a before commit event of the entity. Ensure the return value of the action is returned within the event handler.

2. Add an AllowedToChange Attribute: Add an attribute named AllowedToChange to the entity you wish to monitor for changes.

3. Specify Allowed Changes: Before committing the object, populate the AllowedToChange attribute with the names of attributes and associations that are permitted to change, separated by a semicolon (;).

4. Format for Attributes: Attribute names should be entered exactly as they are defined.

5. Format for Associations: Association names must be prefixed with the module name followed by a dot (.).

6. Wildcard for All Changes: If all attributes and associations are allowed to change, you can use an asterisk (*) in the AllowedToChange attribute.

If you want to allow changes to the attribute FirstName and the association Customer_Order in the Data module, set the AllowedToChange value to: 'FirstName;Data.Customer_Order'
