public ImageButton(String id, ResourceReference resourceReference)
ResourceReference
. That resource
reference will bind its resource to the current SharedResources.
If you are using non sticky session clustering and the resource reference is pointing to a
Resource
that isn't guaranteed to be on every server, for example a dynamic
image or resources that aren't added with a IInitializer
at application startup.
Then if only that resource is requested from another server, without the rendering of the
page, the image won't be there and will result in a broken link.
