Subject Antwort: Re: Re: Re: Customizing scroller by using t:dataTable with t:dataScroller
Date Tue, 02 Feb 2010 10:14:54 GMT
Hi,
Thanks, for the actionListener tip in the t:commandSortHeader.
The only question I have: where do you get the uidata in the 
actionListener from?
Because the only uidata I have stored is from the HTMLDataTable, and this 
index (by using getFirst()) is again, the index of the whole unsorted 
collection.
Is there any other binding necessary, from where I get another uidata with 
the info of the first sorted element of the collection?
thanks,
Klaus

Re: Re: Re: Customizing scroller by using t:dataTable with t:dataScroller






Take a look at the tomahawk example
http://example.irian.at/example-simple-2010012702/pagedSortTable.jsf

you can use the binding attribute of the t:dataTable to get a reference to
the component in your managed bean like this: binding="#{myBean.uidata}".
Then you can use UIData.getFirst() to get the index of the first element 
on
the page, but I guess you already know that.

Futhermore you can set an actionListener on the t:commandSortHeader:
actionListener="#{myBean.actionListener}" with the method in the managed
bean:

    public void actionListener(ActionEvent e)
    {
        int first = uidata.getFirst();
        List<SimpleCar> list = (List<SimpleCar>) uidata.getValue();
        SimpleCar firstItemOnPage = list.get(first);
    }

Now you have your first displayed item on the page.

I hope this helps!

Regards,
Jakob
