RAP 2.1. M1: Flickering on request [message #1024045]

Hi,

We tested our application with the new RAP 2.1 M1.
We experienced some strange behaviour:
When a request takes longer (like more than 3 seconds) all the open Shells (we don't use a maximized shell) dissapear and appear again.
I couldn't reproduce it exactly with a snippet, but there is a "request in progress"-animation displayed rather that hiding all the shells.
In RAP 2.0 there was no such behaviour and in the New and Noteworty for M1
http://eclipse.org/rap/noteworthy/2.1/?build=M1
no additional animation is mentioned (i guess that the dissapearing Shells in our application originate in a problem with this animation)
How can i adapt our application and should i file a bug?

Thanks for your help

Hi Tim,

is it possible to configure this behaviour?

I switched to default theme and the animation is displayed.
We copied the whole business theme with version RAP 1.5. to be indepented of layout-changes in RAP in coming versions.
I checked the default.css and found:

SystemMessage-DisplayOverlay {
background-color: rgba( 128, 128, 128, 0.2 );
background-image: url( resource/widget/rap/display/loading.gif );
}

After inserting this into our business.css the shells didn't dissapear anymore.
The implementation of an animation on long running requests is nice, but it should be configurable in every aspect (time to pass after it is displayed, animation itself).
The question is now: Will these aspects be configurable and is the entry in the *.css the switch to activate the animation? If this is the switch to enable it i would consider this as a bug, because maybe not everyone wants a animation like this but with the dissapearing shells one is forced to.

In that case, the bug is probably in the business theme. You can open
one, but we will fix it in any case.

The theming can configure the color, opacity and animation, as you
discovered. The timeout will likely be configurable, that's the part we
didn't finish. The API already exists internally
(RWT.getClient().getService(
org.eclipse.rap.rwt.internal.client.ConnectionMessages.class );), but
may change until it's made public.

Greetings,
Tim
