white space with word wrapping

Hope someone will help!!!

The following is not doing the word wrapping.  When I
pass <cellValue> without the space translation then
the word wrapping take place....

Thanks
Jay

<fo:table-cell padding="0.6pt" border="0.5pt solid
black" column-number="1">
		      					<fo:block background-color="#FFFFCC"
color="black" font-size="10pt" text-align="left"
font-family="sans-serif">
  <xsl:variable name="cellValue"
select="translate(cell1,' ','&#160;')"/>
	        					<xsl:call-template name="text_wrapper">	
<xsl:with-param name="Text" select="$cellValue"/>
</xsl:call-template> 
		        				</fo:block>		        			</fo:table-cell>


<xsl:template name="text_wrapper">
<xsl:param name="Text"/>
<xsl:choose>
<xsl:when test="string-length($Text)">	    
<xsl:value-of select="substring($Text,1,30)"/>
				      <xsl:call-template name="wrapper_helper">
<xsl:with-param name="Text"
select="substring($Text,31)"/>				</xsl:call-template>
</xsl:when>
<xsl:otherwise>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
				
<xsl:template name="wrapper_helper">
<xsl:param name="Text"/>
<xsl:value-of select="substring($Text,1,30)"/>   
<xsl:call-template name="text_wrapper">
<xsl:with-param name="Text"
select="substring($Text,31)"/>
</xsl:call-template>
</xsl:template>
