Problem with Developing Custom UI toolbar component using JSF

I am Working on developing the custom toolbar component using JSF
Which includes crude operation like ADD Delete etc, and Navigation controls like
Next and Pre.All the operation is working fine to me with single grid in single JSP page
But when I incorporate multiple grids with multiple toolbar .I could not able to achive the toolbar operation binding to specific bean which will be specified as an attribute in the custom tag . I need suggestion to overcome this problem or link to locate the code samples if availabe so that I can simulate the same .
