Command Link as a row of a datatable in JSF

Question

Hi All,
I am new to JSF. I have a Datatable with n number of rows.
I would like to have a command Link in each of the rows, so that when i click the command link i should get the data of the entire row in my edit page.
Can anyone suggest how can i achieve this.

Hi,
Do following:
1- add a datatable in your page and fill it with data comes from database(Assume u have no problem with datatable)
2- add a column as commandLink in data table. e.g.
<h:column>
<f:facet name="header">
<h:outputText value="name" />
</f:facet>
<t:commandLink action="editObject" immediate="true" >
<h:outputText value="#{theobject.name}" />
<t:updateActionListener property="#{objectForm.id}" value="#{objectDto.id}" />
</t:commandLink>
</h:column>
in this code:
"name" is header of column,
"editObject" is defined in navigation rule to navigate to edit page, lets say object form.
"theobject.name" the value that mouse gets finger over it!
"objectForm.id" the pointer to an "id setter" of a managed bean (named objectForm) defined in faces-config.xml. In this setter you can load corresponding data from database
"objectDto.id" the pointer to an "id getter" of a managed bean (named objectDto) defined in faces-config.xml. this getter return the id of the entity row you clicked on.
3- Clearly, you need to defined all managed beans, and dont forget to have a customized setter for id of objectForm (setId) to load the entity from database and fill all editable properties(as you like) in this function (setId).
4- you need a JSF page to redirect to it for editing properties and feed by objectForm
5- Thats it :)
