duplicate items in Document after saving in a bean - xpages

Question

I experience strange but reproduceable behaviour with an XPage which saves its values through a java bean. After copyAllItems to an document there are two richtext items in the document. First is empty, second is filled as expected.
This is my Xpage:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core"
xmlns:xc="http://www.ibm.com/xsp/custom">
<xp:this.data>
<xp:dominoDocument var="docDataSource" formName="test"></xp:dominoDocument>
</xp:this.data>
<xp:div id="test">
<xp:fileUpload id="fileUpload1" value="#{docDataSource.test}"></xp:fileUpload>
</xp:div>
<xp:button value="Label" id="button1">
<xp:eventHandler event="onclick" submit="true"
refreshMode="partial" refreshId="test">
<xp:this.action><![CDATA[#{javascript:registration.testCopyAllItems(docDataSource);}]]></xp:this.action>
</xp:eventHandler>
</xp:button>
This is my java bean method:
public void testCopyAllItems(DominoDocument docDataSource) throws NotesException{
Document docUser = database.createDocument(); // <- get any database
docDataSource.getDocument(true).copyAllItems(docUser, true);
docUser.save();
}
This is the result in the document:
Does anyone have a hint on what could cause the trouble?

This seems to be a "normal" behaviour and I have seen it a lot working with RichtText fields. It shouldn't matter. Notes can deal with a RichText field constisting of more than one item.
As a workaround,
delete the RichText field after copyAllItems() with removeItem() and
copy it with copyItem() separately.
This should result in one item only.
