    <p>I've searched and searched and can't find an answer. Actually all the things I've been reading seem to point to the fact that I've done it correctly, but it's just not working.</p> <p>I'm working on a web mapping application. I want to create a SelectionManager class that would be available to all my mxml files (widgets). The point is that I have multiple widgets that will be selecting stuff from the map and instead of sending events back and forth between widgets, I'd rather have one single class that holds all the information.</p> <p>Right now, I've tried something like this :</p> <pre><code>package SomePackage.utils { public class SelectionManager { public static var _selectionSets:ArrayCollection = new ArrayCollection(); public static var _currentSelectionSet:Object; (Many static functions... ex: AddToCurrentSelectionSet, removeFromCurrentSelectionSet, CreateNewSelectionSet, etc.) } } </code></pre> <p>The _selectionSets is an arrayCollection of objects. The _currentSelectionSet holds one of the objects in the _selectionSets arrayCollection. For example, I will have a BufferSelectionSet and a QuerySelectionSet. When I open the Buffer Widget, I want the _currentSelectionSet to hold the appropriate selectionSet from the _selectionSets Array Collection. This way, anytime I click on something when the Bufferwidget is opened, it will be added to the appropriate selection set.</p> <p>Right now, both my widgets import the SelectionManager class but do not instanciate it. What happens is that both my widgets seem to hold a different SelectionManager while I was expecting them to have the same SelectionManager, with the same static vars.</p> <p>For example, if I set the currentSelectionSet from within my Buffer Widget, i will see that it is set to the Object in the ArrayCollection. But if I look at the currentSelectionSet from my Query Widget, it will be null.</p> <p>I'm not sure if i'm being clear enough, I can give more details if necessary. Like I said, I've looked and looked with no success. Furthermore, I'm not a beginner at Flex and AS 3.0 and have quite a bit of experience in other programming language. I'm just completely stumped on this, maybe it's just been a long day.</p> <p>Thanks for any help.</p> <p>Added Information : </p> <p>MY widgets are in a package parallel to the utils package, i.e.: SomePackage.Widgets</p>

    1. COShow how you are setting the _currentSelectionSet from the widgets.

    2. COI'm setting it through a static function named SetcurrentSelectionSet(SetName:String). The objects in the _selectionSets ArrayCollection have a Name property and a Set property containing. The function loops through all the sets in the SelectionSets and compares names, when it finds one it does something like _currentSelectionSet = _selectionSets[i]

    3. COI don't have the code with me at the moment, so I can't be more precise. But it is set correctly for the widget that set it that is. The other widgets just see a null value

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.
