Hi Manfred, thanks for your reply,
I'm afraid that i don't realy understand; adding an
action listener to my scroll buttons, what this means
exactly? i tryied using <f:actionListener>...like
this:
<f:facet name="first" >
<h:graphicImage
url="../images/datascroller/arrow-first.jpg"
border="0" />
<f:actionListener
type="ro.citrusmedia.lims.web.ui.util.WebTableModel"/>
</f:facet>
but it trows the following exception:
org.apache.jasper.JasperException: Component _id53 is
no ActionSource
And what about the page indexes? the user can jump to
a specific page using also the links to each page
(1,2,3,...n), not just the navigation buttons.
When using the viewRoot's findComponent, i have to
know the name (id) of the dataTable...which i don't
(from my backend bean).
