What I do is:
<tr:column>
<f:facet name="header">
<tr:outputText value="-Delete-"/>
</f:facet>
<tr:commandLink id="delete" text="Delete" action="#{all.deleteUser}">
<tr:setActionListener from="#{user}" to="#{all.toDelete}"/>
</tr:commandLink>
</tr:column>
in the #{all} bean:
private User toDelete = null; (+set/get)
and
public String deleteUser()
{
this.getUserService().removeUser(toDelete);
return ("all");
}
the user service here is injected w/ spring.
The demo is available here:

Hi,
I'm trying to create a (trinidad) table in which it is possible to
remove a row. Next to each row, a "delete"-button is displayed. However,
each time I push the delete button, a wrong row is deleted (for
instance, when I push the delete button next to the first row, the third
row is removed)! Does anyone have an idea why this may be happening???
Regards,
Henk
