Unfortunately, you can not use Clay this way in a dataTable. A data table is a
UIData component. These types of components implement the flyweight pattern.
One set of component definitions for a column is applied to each row as the
model as it is iterated over. For this to work, the clay component would need
to rebuild the subtree for each row. I'm pretty sure that only one attempt to
find the clay config beans that build the subtree is made. The subtree creates
"first class components" that are added to the component tree under the clay
component (children). A dynamic subtree in a datatable would most likely cause
all kinds of problems with state saving too.
