Can any one please help me solving this issue . i know this is a known problem but if any one has a work around for it please let me know.

1. Use <f:setPropertyActionListener> in the link in the table. Thus you set the current entity in a managed bean
2. in the modal panel simply output the value of the currently selected item. For example #{yourBean.current.name} (you have set current on the previous step)
3. The link better be <a4j:commandLink> (or button), so that you can reRender the modal panel in order to obtain the new data
