I found a solution deep in my magic box ;)
put a value-binding attribute on the outputTexts in your dataTable,
just like this:
<h:outputText value="#{entry.subject}"
binding="#{eventsList.specializedOutputText}" />
in eventsList.specializedOutputText,
create a new Instance of SpecializedOutputText and return this.
class SpecializedOutputText should look like the following:
public class SpecializedOutputText extends HtmlOutputText
{
private static Log log =
LogFactory.getLog(SpecializedOutputText.class);
public void encodeEnd(FacesContext context) throws IOException
{
String username =
CalendarFactoryFinder.getGUIContextFactory().getGUIContext().getUserName();
if(username!=null)
{
UIComponent grandParent = null;
if(getParent()!=null &&
(grandParent=getParent().getParent())!=null
&& grandParent instanceof HtmlDataTable)
{
HtmlDataTable table = (HtmlDataTable) grandParent;
Object data = table.getRowData();
if(data instanceof CalendarEntry)
{
CalendarEntry entry = (CalendarEntry) data;
if(entry.contains(username))
{
this.setStyleClass("subject_Column_Private");
}
else
{
this.setStyleClass("subject_Column");
}
}
}
}
else
{
log.error("Could not retrieve username");
}
super.encodeEnd(context);
}
}
HTH!

Martin

hi, i know this is proably not a solution if richard manages to finish
the component, but is all ropes tear you could allways do it in plain
old javaScript in an onLoad function.
it would probably be the fastest, but if you have time, i would
wait for
the component to do the work for you ;)
