Hi,

You should bind 'sortOrder' attribute to the model and and command links to headers, please take a look: http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=dataTable&sample=tableSorting&skin=blueSky

Hi

that example doesn't work correct.

The 'commandLink' in that, works not correct

[nbelaevski]

Hi,

I'm not getting what is the problem with the demo. Can you please add more details about command link that works incorrectly?

Hello Nick

I run the same demo on my server, but i can't see the columns sorted.

I have tried other examples, but the effect is the same.

I seems that the command,(from commandLink) to render the 'datatable' new,

has no effect.

Another problem is,that in the commandLink, the 'setPropertyActionListener target=... value=....'

does not put anything in my Bean.

( A direct call, how #{ dataManager.setValue(3) }, puts the correct value in the bean )

hi.thanks.my problem has been solved.the program need add like this:

public void sortByCapitals() {

        statesOrder = SortOrder.unsorted;

        timeZonesOrder = SortOrder.unsorted;

        if (capitalsOrder.equals(SortOrder.ascending)) {

            setCapitalsOrder(SortOrder.descending);

        } else {

            setCapitalsOrder(SortOrder.ascending);

        }

    }
