Setting org.icefaces.blockUIOnSubmit to true tells ICEfaces that the user interface (UI) should block any subsequent requests until the current request has been processed. This is provided to help prevent double-submits in applications that require this feature.
<context-param>
<param-name>org.icefaces.blockUIOnSubmit</param-name>
<param-value>true</param-value>
</context-param>
This feature can also be controlled on a per-page basis using the <ice:config> tag and setting the desired attribute.
<icecore:config blockUIOnSubmit="true"/>See the documentation on the <ice:config> tag for additional information.
While the UI is blocked there is also a transparent overlay rendered. This overlay has a CSS class assigned so that it can be styled in concordance with the rest of the application. By default the CSS styles are as follows:
.ice-blockui-overlay {
position: absolute;
background-color: white;
z-index: 28000;
opacity: 0.22;
filter: alpha(opacity = 22);
}Providing a stylesheet with new definitions for ice-blockui-overlay CSS class should be enough to override the default styling.
