We ran into some interesting issue like that when we first cut over to spark
using the CSS files shortly after it was released. Some of the components came
up blank like they were not using their default skin files. So we either used
our custom skins or made sure they were assigned properly to components in a
module. It was made worse when I would include a sizeable CSS file in the main
application and any CSS in the main application that wasn't used it tossed...
which meant the module couldn't use that style. Sooo for us it meant....
1. Make sure you have a skin (custom or default) assigned for the trouble
makers. Can assign them in CSS.
2. Any modules not able to load the CSS styles, you can add an empty component
class in your main application to make sure it doesn't toss out those styles.
Like in a script section for your application.
<fx:Script>
import mx.controls.DateField;
import spark.components.SomeComponent;
private var cssWorkAround:Array = [DateField, SomeComponent];
</fx:Script>

Subject: Odd issue with unused namespaces in style blocks
Hi,
Run into a very odd Flex issue today.
Some time ago in a large application we had cleaned up all of the styles and
moved most to a central location, however a few style blocks were left about
with local styles still containing the spark namespaces.
<fx:Style>
@namespace s "library://ns.adobe.com/flex/spark";
.hoverStyle {
symbolColor: #1E78D2;
rollOverColor: #EDF5FF;
color: #1E78D2;
}
</fx:Style>
Using the halo theme the application worked correctly but using the spark theme
sometimes and seeming randomly item renderers would show up totally blank.
Managed to finally find a sequence of steps that causes the issue to happen
every time and it seem the fix to this issue was to remove the unused
namespaces!
<fx:Style>
.hoverStyle {
symbolColor: #1E78D2;
rollOverColor: #EDF5FF;
color: #1E78D2;
}
</fx:Style>
Anyone run into an issue like this or have any idea to why having an unused
namespace would cause item renders to randomly show up blank?
I've not be able to reproduce the issue in a small sample of code but thought I
should email the list just in case anyone run into this issue or knows why this
might occur.
Thanks,
Justin
