set properties of bean managed by dataTable tag

[Jan Bols <ja...@ivpv.ugent.be>]

I have a jsf-page containing the following:
<f:view>
	<h:dataTable var="contact" value="#{allContacts.contactList}">	
	    <h:outputText value="#{contact.firstname}" />
	</h:dataTable>
</f:view>

The allContacts bean is a managed bean and is specified in the web.xml  
file:
<faces-config>
	<managed-bean>
		<managed-bean-name>allContacts</managed-bean-name>
		<managed-bean-class>MyContacts</managed-bean-class>
		<managed-bean-scope>session</managed-bean-scope>
	</managed-bean>
</faces-config>


The allContacts bean contains a list contactList containing contact-beans.  
The contact bean contains a property called myConnection that holds the  
connection to the database.

I want to set that connection property from within the jsf-page or the  
web.xml file but how do I do that? In jstl this can be done with <c:set>  
or in jsp with <jsp:setProperty> but how do I do this in jsf?

Thanks
Jan

That's not what I meant. I want to set the database connection property of  
each Contact bean to a Connection object that is stored in sessionScope.  
The Contact beans are stored in an ArrayList called contactList of the  
allContacts bean. By using the <h:dataTable> I get a reference to each  
contact bean stored in the contactList of my managed bean allContacts. So  
I have a reference to each contact bean and now I want to set the database  
connection property of each contact bean to the Connection object stored  
in sessionScope.

First I though of specifying this in <faces-config> in the web.xml file  
but I can't because the number of Contact beans stored in the contactList  
of the allContacts managed bean aren't known in advance. This means I  
can't make each Contact bean of the contactList a managed bean.

You can set the property using an <h:inputText /> inside your datatable. As 
your datatable interates over the rows in the contactList, you can edit each 
contact bean independently.
 <f:view>
<h:dataTable var="contact" value="#{allContacts.contactList}">
 <h:column>
<h:outputText value="#{contact.firstname}" />
 </h:column>
 <h:column>
<h:inputText value="#{contact.myConnection}"/>
 </h:column>
</h:dataTable>
</f:view>
 Don't forget to define your datatable columns.
