"Request scope" clarification need

[Catalin Kormos <ca...@yahoo.com>]

Hi,

I'm almost very new to JSF, i'm trying to use it on a
new project, more exacly, i'm using myfaces-1.0.7; i
think i need some clarifications about the "session
scope", i guess i don't understand well what is all
about. For example, in tlddocs, for tag
x:dataScroller, there is an attribute, "pageIndexVar";
the following is the description "A parameter name,
under which the actual page index is set in request
scope similar to the var parameter"; 

My question is: how can i get the value for that
parameter from the request scope? i realy need the
value to be able to detect the change in the page
index currenly displayed by the data table. Is there
any other possibility to be informed about the change
of the currently displayed page index, for a data
table?

Thanks, i would realy appreciate some help,

Regards,

Catalin

Hi Catalin,

Have you tried asking the session for the value?

FacesContext.getCurrentInstance().getExternalContext().getSessionMap().g 
et('the value specified for pageIndexVar');

should do the trick.

I'm not sure about the data table.

Hope this helps,
