Perhaps you should modify the values on
the model through the list’s dataProviders editField or replaceItemAt,
since the changes made to the model directly won’t be reflected to the
list?
You could set the list’s dataprovider
once more after you modify the list directly, this might help too.
So something like this:
<mx:List id=”myList”
dataProvider="{sectionModel.region}"
labelField="revenue"/>
function
processCurrentItems()
{
myList.dataProvider.replaceItemAt(0,13);
myList.dataProvider.replaceItemAt(1,14);
myList.dataProvider.replaceItemAt(2,15);
myList.dataProvider.replaceItemAt(3,16);
}
OR
<mx:List id=”myList”
dataProvider="{sectionModel.region}"
labelField="revenue"/>
function
processCurrentItems()
{
sectionModel.region[0].revenue = 13;
sectionModel.region[1].revenue = 14;
sectionModel.region[2].revenue =
15;
sectionModel.region[3].revenue = 16;
myList.dataProvider = sectionModel;
}

Subject: [flexcoders] An
interesting problem with models....
A model, remoteobject, and a list walk into a bar, and the bartender
... j/k
I got a weird problem that I've narrowed down into
a simple
reproduceable test case.
Got a simple model:
<mx:Model
id="sectionModel">
<region
revenue="1"/>
<region
revenue="2"/>
<region
revenue="3"/>
<region
revenue="4"/>
</mx:Model>
And I got a function that just hard code updates
the values:
function processCurrentItems()
{
sectionModel.region[0].revenue = 13;
sectionModel.region[1].revenue = 14;
sectionModel.region[2].revenue =
15;
sectionModel.region[3].revenue = 16;
}
And then these two components displaying data:
<mx:List dataProvider="{sectionModel.region}"
labelField="revenue"/>
<mx:Label
text="{sectionModel.region[0].revenue}"/>
Now the list should show 13,14,15,16 after the
above function is called,
and it does if called from the Application
initialize call. But, if it's
called as a result from a remoteObject call, the
model is updated, but
the List doesn't the change, however the Label
does.
Attached is a working sample.
It turns out the List is updating in the
remoteobject case, but the
display only updates if you move your mouse over
each individual item.
Though why it works fine if the same code is
executed as a result of an
initialize call is beyond me.
In the actual problem that I have - instead of a
list I have a PieChart,
and its display does not update even though the
model is updated (though
to complicate things the exact same code works on
another machine).
Any ideas? Some caching thing?
