Re: [flexcoders] invalidateList or itemUpdated?
Ok. I finally solved it by defining a bindable global variable in the
application and adding the following to the mxml of the item:
borderColor={app.strongNodes.contains(data) ? COLOR_STRONG_NODE :
COLOR_DEFAULT_NODE}
Cheers,
D.

Hi,
Did this solution work? I have done something similar for changing the
border colors of the nodes of a graph but it does not work. I had an array
as a globally scoped variable, and in the item renderer, if the item is in
the array, then the border should be of one color, otherwise another. I
made a local variable in the item bound to the array. However, when I
change the array using the methods, it does not seem to trigger a refresh
in the item renderers.
I also tried to register for the PropertyChange event but it does not seem
that it is ever raised.
Thank you for the help.

Hi,
I have an item renderer which checks an application scoped variable to
determine whether to show a display object. When that variable
changes, I need to make sure all the item renderers for the listbase
object (datagrid) i am using are refreshed. What is the best way to do
this?
the pseudocode for my item renderer would be something like:
if (Application.application.foo) {
showButton = true;
} else {
showButton = false;
}
then in the Application, I need to somehow update the renderers:
foo.val = true;
what do i do here to get the item renderers to update?
thanks!
