My problem is that RichFaces reRender does not work \'under\' the current element in the element tree; only upper elements get rerendered.
Is there any way
reRender works with providing an the id of the target object you want to reRender (inside the same naming container - form most often)id should be a unique string, according to html specreRender allows dynamic value - i.e. reRender="#{myBean.currentItemsToRerender}Based on that I think you should be able to achieve what you want (although it's not entirely clear)
Update:
UIComponent.findComponent(..) has a well-defined algorithm for resolving ids. So for absolute referencing your reRendered id should start with : and then continue through the hierarchy of the naming containers.
