Xpages get a handle on next rowData or Doc in a repeat - xpages

Question

In my repeat control I want to be able to get a handle on data in the next row in order to modify what data is displayed in my current row (I have move up and down actions, and I don't want to display them if the move is not possible).
It seems I should be able to do this. Probably I cannot from within in the repeat itself, as when it is writing the repeat it will not know the data for the next repeat. But shouldn't there be a fairly easy way to get the next document?
Here is a reduced version of my repeat control:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:repeat
id="repeat1"
var="rowData"
indexVar="repeatIndex"
value="#{view1}"><xp:this.facets>
<xp:text
disableTheme="true"
xp:key="header"
escape="false"
>
<xp:this.value><![CDATA[<table class='lotusTable repeatRowColors' border='0' cellspacing='0' cellpadding='0' width='800px'>
<tr class ='lotusFirst lotusSort scope='col'>
<th class ='loutsFirstCell'></th>
<th class ='loutsFirstCell'>Category</th>
<th class ='lotusCenter'>Move</th>
<th>Task</th>
</tr>
</thead>]]></xp:this.value>
</xp:text>
<xp:text
disableTheme="true"
xp:key="footer"
escape="false"
>
<xp:this.value><![CDATA[</table>]]></xp:this.value>
</xp:text>
</xp:this.facets>
<xp:this.rows><![CDATA[#{javascript:var rows:Integer = viewScope.get("rows");
if (rows == null)
{return 5}
else
{return rows}}]]></xp:this.rows>
<xp:tr id="rowDataContainer">
<xp:td
style="width:55px;min-width:55px;max-width: 55px;">
<xp:text
escape="true"
id="computedField2">
<xp:this.value><![CDATA[#{javascript:rowData.getColumnValue("category");}]]>
</xp:this.value>
</xp:text>
</xp:td>
</xp:tr>
</xp:repeat>
</xp:view>

You can get view's next row within the repeat with
var nextRow = view1.getAllEntries().getNthEntry(repeatIndex + 2);
"view1" is the xp:dominoView assigned to repeat control and "repeatIndex" is the indexVar of xp:repeat.
You can get next row document's UniqueID then with
nextRow ? nextRow.getUniversalID() : ""
and the e.g. Form field with
nextRow ? nextRow.getDocument().getItemValueString("Form") : ""
Accordingly, you get the previous row with
var prevRow = view1.getAllEntries().getNthEntry(repeatIndex);
