Any Seam example using RichFace binding attribute?
Hello,
I have this issue for many days. Most of codes are from Richfaces demo. But I need to combine Seam and Richface. It seems that I have to use binding attribute. But I always got error message. I wonder if anyone can help me out? Thanks.
I got below error message:
javax.el.ELException: /conversation.xhtml @22,64 binding="#{dataTableScrollerBean.table}": java.lang.IllegalArgumentException: argument type mismatch
Here is my code:
RichFaces codes
<rich:scrollableDataTable rowKeyVar="rkv" frozenColCount="1" height="400px"

sortOrder="#{dataTableScrollerBean.order}"
