need help editing a row of data.
I have a dataTable that has a list of users:
[
]
When I click this link, I get sent to
com.baselogic.tro.user.impl.UserActionListener.processAction:
public void processAction(ActionEvent anEvent)
throws AbortProcessingException {
log.info("++");
log.info("processAction(ActionEvent anEvent)");
log.info("++");
User tmpUserBean = null;
UIComponent tmpComponent = anEvent.getComponent();
while (null != tmpComponent && !(tmpComponent instanceof UIData)) {
log.info
("---while--");
tmpComponent = tmpComponent.getParent();
}
if (tmpComponent != null && (tmpComponent instanceof UIData)) {
Object tmpRowData = ((UIData) tmpComponent).getRowData();
if (tmpRowData instanceof User) {
tmpUserBean = (User) tmpRowData;
//TODO Implementation of your method
log.info
("++");
log.info("tmpUserBean.toString(): " + tmpUserBean.toString
());
log.info
("++");
}
}
//TODO Exception Handling if UIData not found or tmpRowBean of wrong
type
tmpUserBean prints the row I was expecting, but now I do not know how to get
tmpUserBean in the request and sent back to userDetail.xhtml

Note that the h:commandLink tag can take an actionListener *attribute* as an alternative to using an f:actionListener child. The attribute form is an EL expression, ie can point to a method on your normal backing bean, which I find far more useful than an independent ActionListener class. Regards, Simon
Re: need help editing a row of data.
i display a table of users on listUsers.xhtml Then I want to click the username link and open the selected user in that row on editUser.xhtml so I can edit that user.

Re: need help editing a row of data.
I also tried this:
http://wiki.apache.org/myfaces/ExecutingMethodsFromLinkButtonParameters
then I have this method:
public String prepareForEdit(){
log.info
("++");
log.info
("++");
log.info
("++");
log.info
("++");
log.info("UserBackingBean.prepareForEdit(String)");
log.info("UserBackingBean.user.username(): " + user.getUsername());
String outcome = Constants.FAILURE;
try {
user = manager.getUser(user.getUsername());
log.info
("++");
log.info("user.toString(): " + user.toString());
log.info
("++");
outcome = Constants.EDIT;
} catch (Exception e) {
outcome = Constants.FAILURE;
FacesContext.getCurrentInstance().addMessage(null,
new FacesMessage(e.getMessage()));
e.printStackTrace();
return(null);
}
return outcome;
}
but then when I get redirected to the editUser.xhtml page, the form is
blank.
I even added:
as all the mangedBean's are request scope but I can't seem to populate the
editUser form with data.

What do you mean by "sent back to userDetail.xhtml"?
Note that the h:commandLink tag can take an actionListener *attribute*
as an alternative to using an f:actionListener child. The attribute form
is an EL expression, ie can point to a method on your normal backing
bean, which I find far more useful than an independent ActionListener
class.

Re: need help editing a row of data.
Solution to this issue (using t:updateActionListener and t:saveState)
posted on the previous thread "t:datatable with commandLink and
parameter "
