Reset of datascroller back to first page

[rfuser]

Hello,

If anyone is experiancing problems with datascroller not being refreshed back to first page after content of associated dataTable changes, try following:

- Use latest version of RichFaces 3.0.1 (http://repository.jboss.com/maven2/org/richfaces/richfaces/3.0.1/)
- Build latest source of Ajax4jsf (http://anonsvn.jboss.org/repos/ajax4jsf/)

In your code write something like this:

private void resetDatascroller()
{
HtmlDatascroller scroller = ...
scroller.setFirstRow(0);
}

Call this method each time when dataTable content changes.

This works for me.
Bye

Hi,
I don't understand what to write on the right side of

HtmlDatascroller scroller = ...

Hi,

You need to get instance of your data scroller component. Do that by calling findComponent method which is part of the UIViewRoot like this:

HtmlDatascroller scroller = (HtmlDatascroller)FacesContext.getCurrentInstance().getViewRoot().findComponent("scrollerId");

Of course if the scroller is inside some form you need access it through form id:

HtmlDatascroller scroller = (HtmlDatascroller)FacesContext.getCurrentInstance().getViewRoot().findComponent("formId:scrollerId");

Hello,

I forgot to mention that in case when scroller is inside data table you also need to include table ID in your findComponent "path":

HtmlDatascroller scroller = (HtmlDatascroller)FacesContext.getCurrentInstance().getViewRoot().findComponent("formId:dataTableId:scrollerId");

bye
