Bug with rich text input and partiel refresh?

We are experiencing another issue. This time it is related to working with a rich text field.

Here is how to reproduce it

1/ create a simple form “document” containing a unique “Body” rich text field.

2/ create the following XPAGE

<?xml version="1.0" encoding="UTF-8"?>

<xp:view xmlns:xp=“http://www.ibm.com/xsp/core”>

<xp:this.data>

	<xp:dominoDocument var="mydoc" formName="document" computeWithForm="onsave"/>

</xp:this.data>



<xp:button value="Save" id="button1">

	<xp:eventHandler event="onclick" submit="true" refreshMode="complete">

		<xp:this.action>

			<xp:saveDocument/>

		</xp:this.action>

	</xp:eventHandler>

</xp:button>



<xp:button id="toRefresh" value="Partial refresh">

	<xp:eventHandler event="onclick" submit="true" refreshMode="partial" refreshId="toRefresh">

		<xp:this.action>

			<!--  Saving on the doc on partial refresh make the bug go away... -->

			<!-- <xp:saveDocument/> -->

		</xp:this.action>

	</xp:eventHandler>

</xp:button>



<xp:inputRichText id="BodyField" value="#{mydoc.Body}" />

</xp:view>

3/ to trigger the bug:

- open XPage

- click the "Partial refresh" button

- click the "Save" button

- with your Notes client, check the document. Body starts with special characters ("content type......")

Am i doing something wrong?

Thanks.
