What is an overlay?

An overlay is a window placed over the UI – e.g. for pop-ups or notifications, without disturbing the main content.

Configuration

In the object generator under display of the generated object, choose the matching constellation.

Overlay constellation in the object generator.

Layout design

For a dialog the minimum size is evaluated – best to use fixed values and let one row fill the remaining space.

Important

After adjusting the layout, save the object generator again – this analyses the layout and remembers the minimum size.

Server rule order

Before opening, the object generator rule runs. On OK in the overlay a combined insert/update rule must exist for the overlay object:

@Rule(name="VerfahrenErstellen", description="VerfahrenErstellen")
public class VerfahrenErstellen implements InsertRule, UpdateRule {
    public void update(UpdateContext context) throws BusinessException {

        insertVerfahren(context, context.getBusinessObject(ObjektgeneratorVerfahren.class));

    }


    public void insert(InsertContext context) throws BusinessException {

        insertVerfahren(context, context.getBusinessObject(ObjektgeneratorVerfahren.class));

    }
