RE: [flexcoders] Re: Item Renderer Not Updating
Set some selected props to true before assigning the dp to see if it is
picking it up.

I went and created a component as the itemRenderer, like this:
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml width=100%
height=20
mx:CheckBox id=myCheckBox
selectedField=selected
label={data.label}
x=0 y=0
height=20 width=100%/
/mx:Canvas
As you can see I've set the selectedField property to selected, but
that still doesn't seem to effect anything. If some of the CheckBoxes
are selected, and the user does the correct gesture, I have a loop
that sets the 'selected' property of the model to false. I expect
that to deselect all of the CheckBoxes. Yea not happening.

The ResourceModel and ResourceItemModel classes are [Bindable]. Is
that what you're talking about?
Also, I was thinking that the 'selected' property of ResourceItemModel
is not used for the 'selected' property of the CheckBox in the
itemRenderer. The 'label' property of the model seems to work, but is
'selected' not the appropriate variable to use? Should it be
something like 'data' perhapse?

Ok, next thing to see is if collectionChange events fire when the values
are reset to false.

I need to correct my previous post with some changes I've made.
I changed the model property to 'isSelected', and am binding that to
the 'selected' property of the CheckBox like so:
mx:CheckBox id=myCheckBox
selected={data.isSelected}
label={data.label}
x=0 y=0
height=20 width=100%/
Now if I set some of the values to true in the command class listed
below, it picks it up. So that is working, but if do the user gesture
that is suppose to reset all values to false, that doesn't happen
(even though the model is set correctly).
Thanks for the help!

I did the following in my command class:
for (var i:uint = 0; i data.result.length; i++) {
// Get the current result and create a ResourceItemModel from it
userSummaryVO = UserSummaryVO(data.result[i]);
item = new ResourceItemModel();
item.firstName = userSummaryVO.firstName;
item.lastName = userSummaryVO.lastName;
item.username = userSummaryVO.username;
item.selected = true;
// Add the item to the model
__model.userSummaries.addItem(item);
}
