white screen when waiting for response [message #1060946]

Hello,

after switching from RAP 1.5.1 to 2.1 M2 I always got white screens, when doing some action in the application. The application is running on a JBoss AS 7 server. When I start the app locally with jetty I got a nice light grey transparent screen and see an action wheel. Is this possible on war installations too?

thx, Dirk

Hi Dirk,
do you have your own custom theme? It seems that during the migration
from 1.5.1 to 2.1 M2 your theme is not updated with all the needed
properties from RAP 2.0+. Or... in case it is, the theme (CSS) is not
included in the war.
Best,
Ivan

Hello Ivan,

I have activated from the examples the business theme, which looks like as expected...

regards, Dirk

Hi André,
please look at your theme about the following CSS:
....
SystemMessage-DisplayOverlay {
background-color: rgba( 128, 128, 128, 0.3 );
background-image: none;
}
....
Do you have it? If not add it to your theme and try again.
HTH,
Ivan

André,

when a response from the server is delayed, the screen is blocked by an
overlay to prevent further interaction. The look of this overlay can be
changed in the theme, as Ivan explained.

However, you shouldn't usually see this overlay often, unless you have
an unusually long network latency. If you do anyway, you should have a
look at the response times.

Long response times can be caused by time-consuming operations running
directly in the UI thread. Could this be the case in your application?

Regards,
Ralf

Hi again,

solved for me now too, after deleting all temporary files on the jboss server and undeploying the application. I also added the latest example design to the war file.

regards, Dirk
