XPages ViewPanel setStartKeys with date value does not work - xpages

Question

i got a simple code sniped to jump to a specific entry in a viewPanel control
var c:com.ibm.xsp.component.xp.XspViewPanel = getComponent("viewPanel1");
var ds:com.ibm.xsp.model.domino.DominoViewData = c.getDataSource();
ds.setStartKeys(MYVALUETOSEARCH);
c.gotoRow(c.getRowIndex());
This works perferct when the sorted column is a string but it did not work when the column is a date.
It seems it is not allowed to pass MYVALUETOSEARCH as NotesDateTime
Any Ideas to solve the problem?
EDIT:
I use Domino 9.0.1 FP7
Here is the complete sample
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:inputText
id="filter">
<xp:dateTimeHelper
id="dateTimeHelper1"></xp:dateTimeHelper>
<xp:this.converter>
<xp:convertDateTime
type="date"></xp:convertDateTime>
</xp:this.converter>
</xp:inputText>
<xp:button
value="Label"
id="button1">
<xp:eventHandler
event="onclick"
submit="true"
refreshMode="partial"
refreshId="viewPanel1">
<xp:this.action><![CDATA[#{javascript:var c:com.ibm.xsp.component.xp.XspViewPanel = getComponent("viewPanel1");
var ds:com.ibm.xsp.model.domino.DominoViewData = c.getDataSource();
var filter = getComponent("filter").getValue();
var dt:NotesDateTime = session.createDateTime(filter);
ds.setStartKeys(dt);
ds.refresh();}]]>
</xp:this.action>
</xp:eventHandler>
</xp:button>
<xp:viewPanel
rows="30"
id="viewPanel1"
viewStyle="width:100%">
<xp:this.facets>
<xp:pager
partialRefresh="true"
layout="Previous Group Next"
xp:key="headerPager"
id="pager1">
</xp:pager>
</xp:this.facets>
<xp:this.data>
<xp:dominoView
var="view1"
viewName="test">
</xp:dominoView>
</xp:this.data>
<xp:viewColumn
columnName="date"
id="viewColumn1">
<xp:this.converter>
<xp:convertDateTime
type="date"></xp:convertDateTime>
</xp:this.converter>
<xp:viewColumnHeader
value="date"
id="viewColumnHeader1">
</xp:viewColumnHeader>
</xp:viewColumn>
</xp:viewPanel>
The view "test" just contains 1 sorted column that contains a date value

Providing NotesDateTime start key for the ViewPanel would work fine if you make sure the key is of NotesDateTime type. Using component value as a key without converter may give you String instead of expected NotesDateTime value.
The following code works in my 9.0.1 environment:
var c:com.ibm.xsp.component.xp.XspViewPanel = getComponent("viewPanel1");
var ds:com.ibm.xsp.model.domino.DominoViewData = c.getDataSource();
var filter = viewScope.get("date");
var dt:NotesDateTime = session.createDateTime(filter);
ds.setStartKeys(dt);
ds.refresh();
