Most of the value bindings in myfaces are readonly. I´m not sure what
the spec says about this but you are right it is better to make those
value bindings read/write.
One way I see is to use a binding for the datatable and get the first
value from there.

Thanks for the info Mathias.
Despite I don't get the ClassCastException anymore, the right page of my
dataTable isn't displayed.
I have initted the attribute value of my bean to new Integer(0). Then, by
displaying its value through the pages scrolling, I see that it keeps its 0
value (normal as I also saw that the setter of the attribute is never called).
I can't imagine that it is the programmer's work to update this attribute value ... no ? And if so, where and how ?
Regards, Clément.

Take a look into the javadoc for UIData. It´s just the integer value of
the zero based row index for the first row of the table. The instance
should be of java.lang.Integer.

Hi,
I also need this possibility, and enjoyed to see that it was possible
to do it. However, what I tried doesn't work. Like Mathias said, I try
to use the "first" property of the dataTable, binding it to a backing
bean attribute. The problem is that I have a ClassCastException when
accessing it :
10:05:55,118 INFO [STDOUT] java.lang.ClassCastException:
fr.edic.cormag.view.datastructure.StockData
10:05:55,118 INFO [STDOUT] at
javax.faces.component.UIData.getFirst(UIData.java:723)
10:05:55,180 INFO [STDOUT] at
org.apache.myfaces.component.html.ext.HtmlDataTable.getFirst(HtmlDataTable.java:324)".
I thought that the type of the backing bean attribute for the "first"
property should be the same as the data row displayed in the dataTable
(in my case : StockData), but it seems not ...
So my question is : what is the type of the backing bean attribute to
bind the "first" property of a dataTable component ?
Thanks,
Clément.

When the action of your button is invoked get the current value of the
first property of the datatable. You can use binding for this. You have to store this value somewhere and by using a value binding for
the first property of the datatable it is possible to provide an inital
value (your stored value) for that:
<x:datatable ... first="#{data.first}" binding="#{data.datatable}">
</x:datatable>

I have a page displaying data using both the x:dataTable and
x:dataScroller tags. I'd like to know if it is possible when I visit
the page that it "jump" or remember to goto a particular page, say
page 2 instead of page 1.
For example, I have 100 items to display with a pagesize of 10 (i.e. rows =
10). That would give me 10 pages to scroll through (100 / 10 = 10). From
this page a user may click on an item in order to the view another
page with another table displaying details. From the details page
they'd like to go back to the summary page and return to viewing the
same page there were on. The users cannot use the browser's back
button. The back function is current a h:commandLink button tied to a
navigation-rule that points to the summary page. When they click on
it they go back but the summary dataTable jumps back to the first
page.
I am using the nightly build from 31-Jul-2005.
