So I've been wanting to use a Date View for a while, but I've not had the time I need to sit down and puzzle it out. And (soap box here) the examples given are pretty complex. I do have a sample based on Brad's work that I will be posting. But as I get that together, here is a tidbit.
When you use a Data View, you are only given the option of selecting a Domino View. I wanted to see if you could do it with a collection. It turns out you can. What I did was this (in my odd discovery process) I created a DataTable based on a NotesViewEntryCollection of all entries in a view. I copied the <xp:this.value> node from it and replaced the <xp:this.data><xp:dominoView ...> nodes in the dataView. And the page renders. I've only put a pager in to see if it's got full functionality, and that's working, so I suspect that various other things will as well.
Here is the entire XPage. It should work for you just changing the view name and the field you get. Plus, it's a start to using the Data View if you've not started yet :)
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core" xmlns:xe="http://www.ibm.com/xsp/coreex">
<xe:dataView
id="dataView1"
var="rowData"><xp:this.facets>
<xp:pager
layout="Previous Group Next"
partialRefresh="true"
id="pager1"
xp:key="pagerTopLeft">
</xp:pager></xp:this.facets>
<xp:this.value><![CDATA[#{javascript:var nView:NotesView=database.getView('Name');
var nVEC:NotesViewEntryCollection=nView.getAllEntries();
return nVEC;}]]></xp:this.value>
<xe:this.summaryColumn>
<xe:viewSummaryColumn value="#{javascript:rowData.getDocument().getItemValueString('Subject');}"></xe:viewSummaryColumn>
</xe:this.summaryColumn>
</xe:dataView></xp:view>
Cheers,
Brian

Great tip! I've used this with arrays of JavaScript objects as well (as a way to minimize overhead when refreshing). The Data View is an incredibly flexible control.

@Brad - Thanks Dude! I'm a fan of yours - and so it's an honour to see you commenting here.
Can/will you post an example of using JS Objects? Like so much of what you do, I'd like to adopt it.

Below is a working example (it looks like it's stripping out the reference to the SSJS script library, but I think everything else is in tact).
Basically, I set up a script library function to walk a view and build an array of objects with data to display. The data view page includes the script library and gets the data by setting the "var" property to: return getData(); (there's no "data" property to set, because it's not using a view data source). Each data object has a Name, City, and Country property. I set the Name as the summary column and the other two as extra columns.
I've used this in combination with a scope variable to check whether I should re-build the data or just leave it as is, so it's not refreshing as much. I don't have benchmarks on it, but it makes sense to me conceptually.
[Data View XPage]
<xp:view xmlns:xp="http://www.ibm.com/xsp/core" xmlns:xe="http://www.ibm.com/xsp/coreex">
<xp:this.resources>
</xp:this.resources>
<xe:dataView id="dataView1" var="dvRow" value="#{javascript:return getData();}">
<xe:this.summaryColumn>
<xe:viewSummaryColumn value="#{javascript:return dvRow.Name;}">
</xe:viewSummaryColumn>
</xe:this.summaryColumn>
<xe:this.extraColumns>
<xe:viewExtraColumn value="#{javascript:return dvRow.City;}" columnTitle="City">
</xe:viewExtraColumn>
<xe:viewExtraColumn columnTitle="Country" value="#{javascript:return dvRow.Country;}">
</xe:viewExtraColumn>
</xe:this.extraColumns>
</xe:dataView>
</xp:view>
[Script Library Function]
function getData() {
var data = [];
var vw:NotesView = database.getView('ByName-First');
var nav:NotesViewNavigator = vw.createViewNav();
var ve:NotesViewEntry = nav.getFirst();
while (ve != null) {
var columnValues = ve.getColumnValues();
var thisRow = {};
thisRow.Name = columnValues.elementAt(0) + ' ' + columnValues.elementAt(1);
thisRow.City = columnValues.elementAt(3);
thisRow.Country = columnValues.elementAt(6);
data.push(thisRow);
var tmpentry = nav.getNext();
ve.recycle();
ve = tmpentry;
}
return data;
}
