The tl:ListModelBuilder is a tl:ModelBuilder used for components that represent a set of objects (tl:TableComponent, tl:GridComponent, ...).

The method

Object getModel(Object businessModel, LayoutComponent aComponent);

in the ModelBuilder is to be called in the ListModelBuilder on

Collection<?> getModel(Object businessModel, LayoutComponent aComponent);

should be changed.

Code migration

• In tl:ListModelBuilder, the return type of getModel(Object, LayoutComponent) needs to be changed from Object to Collection<?> (or something more concrete).
• In tl:TableComponent, ListModelBuilders must now be configured. If a tl:ModelBuilder is configured that is not a ListModelBuilder, the login will fail with a ClassCastException.

Test

Refactoring. No additional test.
