Hi,

you can inject the create action and then define a beforeActionPerformedHandler like this:


class CustomerBrowse extends AbstractLookup {

    @Inject
    CollectionDatasource<Customer, UUID> customerDs;

    @Named("customerTable.create")
    CreateAction createAction;

    @Override
    void init(Map<String, Object> params) {

        createAction.setBeforeActionPerformedHandler(new Action.BeforeActionPerformedHandler() {
            @Override
            boolean beforeActionPerformed() {
                return customerDs.size() < 2;
            }
        });
    }
}

Bye
