Re: Dynamic clay in a datatable
Finally I found a solution! Thanks Gary to point me on the right way.
In resume, it consists in duplicate the clay component for every
distinct jsfid (every clay page template), and setting the rendered
property accordingly.
To achieve it the more easy way I found is to create a new jsf component
that adds 1 child for page setting the rendered attribute with a value
expression.
Thanks.

Could you try first this more direct way and see what happens?
t:dataTable value=#{home.banners} var=c
t:column
clay:clay id=prueba jsfid=#{c.jsfid}/clay:clay
/t:column
/t:dataTable
Not sure that the symbol tag is being evaluated in time to be
available for the clay component.
I have not used clay's jsp tags but have done something like this
before with html templates.

And WDynamicClay is an xml component definition:
component jsfid=WDynamicClay extends=clay
attributes
set name=clayJsfid value=@page/
/attributes
/component
The managedBeanName's attribute jsfid returns a different clay html
template but always the last template is rendered.
I tried other alternatives but always with identical result:
- Using a ShapeValidator
- Create a JSF component that adds a clay component
- Extending the Clay component
Thanks in advance.

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.
