Hi Jan,
Remember: You should not do bussiness logik in the presentation layer. Thatīs
why it is and will be not possible that way.
Try to use a managed bean which initializes and holds your contact list.
Provide a getContacts() method in that bean which returns the initialized
contact beans. While initializing the contacts you take the connection and call
the setConnection method for each contact.
Example:
<h:datatable value="#{data.contacts}" var="contact">
<h:column>
...
<h:outputText value="#{contract.name}" />
</h:column>
...
</h:datatable
Ps: do you load every contact through a separate database query? If so try
loading the contacts in a single database call. It will increase performance a
lot.
