[ovirt-devel] popup dialog

[Vojtech Szocs]

Hi,

forgot to mention, one more thing needs to be done:

  // in PresenterModule
  bindPresenterWidget(TemplateBackupPopupPresenterWidget.class,
    TemplateBackupPopupPresenterWidget.ViewDef.class,
    TemplateBackupPopupView.class);

(Above binds popup PresenterWidget/View within GIN DI context.)

Regards,
Vojtech
