h:dataTable loses selected row styleClass after submit

In 开发者_如何学运维my dataTable when a row is clicked it gets marked with some color. But then this mark disappears because submit occurs. But i re-render only some other part of the page and not the table, so why does it occur? How can i fix this? The code:

You can use firefox and "firebug" plugin to inspect the element in real time to find out what's going on. It could be that something about your update is breaking the inheritance of the style...
