    <p>you can instantiate objects without assigning them to a variable ... instead of storing a reference to an object in a variable, you can directly pass it to a function, as argument, or you can pass some other object as a parameter to the constructor, that'll allow the object to register it self elsewhere ... for example, this code will work perfectly:</p> <pre><code>(new URLLoader(new URLRequest("someURL"))).addEventListener(Event.COMPLETE, someEventHandler); </code></pre> <p>this code instantiates 2 objects, none of which is stored into a variable ...</p> <p>so instantiation has nothing to do with variables at all, which is, why the "first step" is not a part of an instantiation process ... instantiation of an object is <code>new SomeClass(someParam_1,...someParam_n)</code> ...</p> <p>and as Epskampie pointed out, the "third step" is also not a part of instantiation, because it only works with <code>DisplayObject</code>s ... it is not "instantiating on the stage", it is "putting them on the display list" ... also, most of the time, you put them into (grand)children of the stage, rather than the stage itself ... you may also simply decide not to put a <code>DisplayObject</code> on the display list (there are several scenarios, where that makes sense) ...</p> <p>so yeah, i would not talk about "layers" ... what you describe is a possible approach of creating a <code>DisplayObject</code> on the display list, that consists of 3 "steps" (the first being optional), but not "layers" ... and there is no analogy to MVC ... flash <code>DisplayObject</code>s are the base for creating a view ... MVC in ActionScript works pretty much as in any other language ... you create model, controller and view objects as you would in any other language ... instantiation is the same for all, but for the latter, it requires an extra step, to display them ...</p> <p>hope that helps ...</p> <p>greetz</p> <p>back2dos</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
