I am using PrimeFaces 5.2 and at a place in my web app. I am displaying a data table is which corresponding to each row. I am giving an edit link (<p:commandLink>) to edit the the fields of corresponding entity on next page but the link is not working at all. Here is the XHTML content.
<p:dataTable id="tickets" var="ticket"
value="#{ticketController.ticketModels}" paginator="true" rows="10"
filteredValue="#{ticketController.filteredTickets}">
<p:column headerText="Ticket Id" sortBy="#{ticket.ticketId}">
<p:commandLink action="viewDetailedTicket">
<h:outputText value=" #{ticket.ticketId}"></h:outputText>
</p:commandLink>
</p:column>
<p:column headerText="Summary" filterBy="#{ticket.summary}"
filterMatchMode="contains" sortBy="#{ticket.summary}">
<h:outputText value="#{ticket.summary}" />
</p:column>
<p:column headerText="Priority">
<h:outputText value="#{ticket.priority}" />
</p:column>
.
...............................
</p:dataTable>
The following is my backing bean:
#ManagedBean
public class TicketController {
#ManagedProperty(value = "#{ticketpojo}")
private Ticket ticket;
private TicketDao tDao;
private TicketModel ticketModel;
public TicketModel getTicketModel() {
return ticketModel;
}
public void setTicketModel(TicketModel ticketModel) {
this.ticketModel = ticketModel;
}
public TicketController() {
tDao = new TicketDao();
}
public String viewDetailedTicket() {
ticketModel = tDao.getTicket(ticketId);
return "viewDetailedTicket";
}
}
When I hover, over the link , the tooltip at the bottom of the browser shows http://localhost:8080/JSF_1/view/viewTicket.xhtml# , a '#' is appended to the end of the current page URL. When clicked it remains on the same page.
I have tried putting the link outside the data-table that also didn't work .

A commandLink or any action that you'd like to do with JSF/primefaces must be inside a form. Otherwise no HTTP Post can be performed. I suggest to use one form for the whole datatable. Otherwise there will be a lot of forms for the multiple rows.
