some background-colors in tablecells not shown

[Tobias . Soloschenko]

Hello,

i've got the problem that for example the hex-color-code #f3f3f3 is not shown
as background-color in table-cells. I'm using it similar this way:

<fo:table-cell>
        <xsl:if test="$bgcolor!=''">
                <xsl:attribute name="background-color"><xsl:value-of select="$bgcolor"/></xsl:attribute>
        </xsl:if>
        <!-- I've printed the color value with a block to check it: -->
        <fo:block><xsl:value-of select="$bgcolor"/></fo:block>
</fo:table-cell>

I'm using fop 0.20.5 (now ;) ) and java 1.3 other colors like #339933 and #efefef are shown.
what could that be?

there are no errors during the compilation and no warning about background-color properties.
I'm using the avalon-logging in debug mode.

kind regards
