dataSrcoller, how to send page number to backing bean

[dkane]

Hello.

Trying to bind datascroller page index to backing bean.

<rich:datascroller for="userTbl" pageIndexVar="pageIndex">
 <a:actionparam name="pIndex" value="#{pageIndex}" assignTo="#{userAdmin.pageIndex}"/>
</rich:datascroller>

Backing component :

int pageIndex;

 public String getPageIndex()
 {
 return String.valueOf(pageIndex);
 }

 public void setPageIndex(String p)
 {
 log.info("Page index set to "+p,null);
 try
 {
 this.pageIndex=Integer.valueOf(p);
 }
 catch(Exception ex)
 {
 this.pageIndex=1 ;
 }

 }

When I switch pages, the log message is always "Page index set to null".
Tried to access pageIndex as integer not string, the result was "must be a number".

What is the correct way to get page index ?
Thanks

You are welcome :)
The problem of saving-restoring the selected number in dataScroller is important for my current project.
When user leaves page with dataTable & dataScroller and then gets back, he must see the same page and portion of data. But so far I am unable to bind dataScroller position to backing bean. It resets to first page upon rerendering.
Looking forward to new version. Thank you.

I've just ran into the same issue. Thanks for the post.

Just tested 3.1.3.CR4 , see code in the first message of this topic.
Now result is not null . But setter's logging always shows me the previous value of datascroller.
I.e. when I click [2] on datascroller, message from logger is "Page index set to 1". After that I click [1] and message is "Page index set to 2", and so on.

It works just as you defined. Look, pageIndexVar - keeps current page index. So after you hit the button - it stores under the property you need. :) No magic.

To get actual pageIndex from server side - use binding.

Is this bug also the reason why my datascroller doesn'T save the current page when i leave to another page, and then switch back to my page with my datascroller?

Could you please let me know by sample code how to use the binding parameter in rich:dataScroller.
