365 Adopt the Autoform AutoFormBrandOfCar and rename it to ManageBrand
366 Rename the Class action that brings that form up to have the same name as the form
367 Delete the 2 actions that now show errors due to use of vCurrent_<oldname>
368 Delete all the viewModelColumns except the Name
369 Make sure you understand the opt-in-opt-out for actions
370 Add a image - BrandImage :Blob to class BrandOfCar
371 Add a column that shows BrandImage in ManageBrand view
372 Remove the presentation from the BrandImage column
373 Start the application - upload images to the different brands
374 Add a new ViewModel to seek for BrandOfCar, name it BandSeeker, use the UIFirst to get a copy of SeekerAutoForm-logic
375 Set sortorder on Global Action BrandOfCar, make sure you understand how Action order is handled in menus
376 Drop all the autoforms from the model, note that a lot of actions and viewmodels are now removed from the app
377 Note that that the logic to jump on first click is in effect whenever there is only 1 available navigating action
378 Right click the the BrandOfCar class and check the UsedBy list - find out where BrandOfCar is used and add the BrandImage to these places
379 Make sure you try a few of the ways to find the proper expression for showing the BrandImage from the different contextes, "Add Column", "Add column from model", "manual expression typing"
380 Fix up the NewCar action that does not have a view (since it pointed to an AutoForm that we dropped) - make it show view ProperCarView
381 Add a SingleLinkWithSetter/Picker/Combobox in ProperCarView to set the BrandOfCar link, call the column BrandOfCarForAdmin
382 Note the access issues with ProperCarView, anyone can set the BrandOfCar
383 Fix the ReadOnly expression to only allow admin to change the BrandOfCar
384 Run the app; Check with your two users - a and b - where a is admin and tb is not - verify that you understand the readonly expression
385 Go back to the app - and make the BrandOfCarForAdmin column invisible for anyone not being admin - do this by checking the FollowEnable box behind the VisibleExpression
386 Then we discover that the RegistrationNumber can be changed by anyone... - Fix this by first setting the accessGroup IsAdministrator on the action NewCar
387 Move the readOnly expression from combobox BrandOfCarForAdmin to the readOnly expression for the whole ProperCarView
