How to use 'white-space' property in fop xsl-fo?

I am using FOP 2.2 in order to generate pdf file from xml documents. FOP documentation is here http://xmlgraphics.apache.org/fop/

The pdf document is generated fine. However, I keep on getting this ERROR message.

    ERROR: Invalid property value encountered in white-space="pre-wrap": org.apache.fop.fo.expr.PropertyException: null:118:-1: No conversion defined pre-wrap; property:'white-space' (See position 119:-1)

xsl template has the below code:

<xsl:attribute name="style">
    <xsl:text>white-space: pre-wrap;</xsl:text>
</xsl:attribute>

(I guess you are converting HTML to XSL-FO using XSLT, as style is not a valid FO attribute)

The error message is telling you that pre-wrap is not a valid value for the property white-space; the only allowed values are normal, pre and nowrap.

However, in XSL-FO white-space is just a "shorthand property" to quickly control a set of whitespace-related properties, so you should be able to achieve the desired result directly setting those properties instead:

linefeed-treatment="preserve" 
white-space-collapse="false" 
white-space-treatment="preserve"
