Hmmm, alright I think I narrowed down the
problem and with coffee this morning I’m a bit clearer on the problem
here.
The binding is working fine (the class is bindable, so properties don’t
need to be – using Cairngorm 2) because I’ve tested the exact same
thing with a label/string and the same ICV/datagrid and it works….but my
chart won’t update. To make it real simple, I’ve got a basic
example:
<mx:DataGrid id="HourGrid"
dataProvider="{model.hourData}" width="100%"
height="100%">
<mx:columns>
<mx:Array>
<mx:DataGridColumn dataField="name"
headerText="Hour"/>
<mx:DataGridColumn dataField="revenue"
headerText="Revenue" labelFunction="dataGridCurrencyFormat"
textAlign="right"/>
</mx:Array>
</mx:columns>
</mx:DataGrid
<mx:LineChart id="salesChart"
dataProvider="{model.hourData}" showDataTips="true"
width="100%" height="100%"
dataTipFunction="formatDataTipTotals">
<mx:horizontalAxis>
<mx:CategoryAxis dataProvider="{model.hourData}"
categoryField="name" name="Hour"/>
</mx:horizontalAxis>
<mx:verticalAxis>
<mx:LinearAxis minimum="0" maximum="1500"
labelFunction="currencyFormat" name="Revenue"/>
</mx:verticalAxis>
<mx:series>
<mx:Array>
<mx:LineSeries
lineSegmentRenderer="mx.charts.renderers.LineRenderer" id="current"
yField="revenue" showDataEffect="{interpolate}" >
<mx:lineStroke>
<mx:Stroke color="#000000" weight="3"/>
</mx:lineStroke>
</mx:LineSeries>
</mx:Array>
</mx:series>
</mx:LineChart>
I’ve even removed everything from the LineChart besides the
horizontalAxis (removed dataTipFunctions,verticalaxis, etc…) making it a
5 lines of code chart and it doesn’t update even the horizontalAxis.
These are right next to each other in code as shown above.
As you can see my datagrid comes out fine, but my chart doesn’t update
and stays empty....
Ideas?

Cairngorm Model binding problem
You also need to put [Bindable]
in your ModelLocator class.

public var ICV: ICollectionView;

Cairngorm Model binding problem
Alright,
I’m attempting to move my little dashboard to Cairngorm and it’s
going alright but now I’ve got a real basic problem and it’s
stumping me – I know it’s something little but I’m stuck. In
my ModelLocator instance I have an ICollectionView. Service gets called by
event/delegates and the command responder is setting the model.ICV
correctly….but my chart which uses dataProvider=”{model.ICV}”
isn’t updating. Now, since I made in my chart component:
[Bindable]
public var
model : ModelLocator = ModelLocator.getInstance();
<mx:LineChart id="salesChart"
dataProvider="{model.ICV}"….
And in my ModelLocator file:
public var ICV: ICollectionView;
I’m assuming the problem is somewhere in the binding – do I need to
broadcast an update event to the Chart….that doesn’t sound right
though, anytime an ICV changes I shouldn’t have to do that right? Bah,
having a headache isn’t helping….anyone got any ideas where I went
wrong?
