Extensions

This project demonstrates how to extend an entity and corresponding screens defined in an application component.

Suppose you have Department entity in your project and you want to add an attribute of this type to the standard User entity defined in the platform (i.e. in com.haulmont.cuba component). Please look at the following project items:

• If you open the ExtUser entity in Studio, you can see that it has User in the Parent class field and the Replace parent checkbox is selected.

• There are two ExtUser views with the same names as used for User in its browser and editor screens. Please notice that they extend base views and add the department attribute.

• The ext-user-browse.xml and ext-user-edit.xml screens extend the corresponding screens from the platform. They have the same identifiers as base screens.

• The message pack of the new screens includes the message packs of base screens. See com/company/sample/web/extuser/messages.properties.

• There is a custom main window: ext-mainwindow.xml, adding a label for displaying department of a current user. In its controller ExtAppMainWindow, the user is reloaded with a view containing department attribute and the department name is set to the label.

Based on CUBA Platform 6.10.1
