Trent,
What I do is wrap the domain object in a web-tier object. The web-tier
object has two properties: the domain object and a "selected" boolean
property. Then I have a column in my dataTable like so:
<h:column>
<f:facet name="header"><h:outputText value="Selected"/></f:facet>
<t:selectBooleanCheckbox value="#{data.selected}"/>
</h:column>
When I need to do processing, I grab the list of web-tier objects and
check to see which ones are selected.

Hi there,
When interacting with the DataTable component I have to define a
boolean field on the domain object that represents a row in the table
to allow multiple checkbox selection. Is this to right way to proceed
with this development?
I could for example have a domain object called 'Student' that has
been delivered to me by others in an organisation. I do no control
the development of this object, but to interact with it through a
multiple select table I have to define a UI only used field on the
above object. If on the other hand I settled for single radio button
selects on the table then I could use the getter methods on the UI
component to identify which object the user is interacting with.
I am new to JSF but to me this seems like a cross over of layers. To
me the domain object should not have to define this field. I was
looking at the example under the trinidad/ADF project and there seems
to be a table component that would allow me to gain a list of the rows
that were checked.
Is there anything I have over looked within the core myfaces API
project and/or tomahawk projects? How do other navigate through this
issue? Do people end up creating wrappers for the data and then
display them within the DataTable instance?
Many thanks
Trent
