J2.5 talk:Developing a MVC Component/Basic backend

Items to be adding/changed on this page:

Note that if using core J! javascript in a form, id="adminForm" must also be included.

Shouldn't references to $db->getDBO() be changed to $db->getDbo() ?

And what is this comment referring to? "The _populateState method is, by default, automatically called when a state is read by the getState method."

Admin Forms in J2.5

Aparently, for the JToolbar Icons to work properly in J2.5, the form elements need the id "adminForm" to be assigned to them. I changed this in admin/views/helloworlds/tmpl/default.php. However, it also needs to be changed in the packages...

JController::display

The function declaration has been changed from

public function display($cachable=false)

TO

public function display($cachable=false,$urlparams=false)

How to access backend component & task icons not displaying

The tutorial is unclear on how to access the backend component. I did not find it accessible via the administrator UI; however I could run the component with:

http://localhost/joomla/administrator/index.php?option=com_helloworld

However, underneath the menu bar (Site, Users, Menu...), there is an empty toolbar without any task icons (e.g. Save, Save and Close, Close...). So I can "check" id 1 (Hello World!) and/or id2 (Good bye World!), but then cannot "Save" since there are no task icons.

Is this backend supposed to configure the "Required Settings" options when Editing a Menu Item? i.e. when I add a Menu Item and select "Menu Type", is the purpose of this backend component to specify what options I have in the "Required Settings" drop-down box?

I have identified (hopefully) some outstanding obstacles to getting this backend component to function in 2.5; I hope someone knowledgeable can address these issues so Part 07 becomes a more effective tutorial.
