XSLTC and external functions

[Perez Carmona, David]

Hi all,

I have this Java class

public class Tbl {
  public static Number getAncho(Number anchoCols, Number numCols);
  ....
}

and this stylesheet:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
        xmlns:tbl="xalan://fcc.ima.pdf.Tbl">

        <xsl:template match="a">
                <xsl:variable name="v-anchos">
                        <xsl:for-each select="vista">
                                <ancho><xsl:value-of 
select="tbl:getAncho(sum(columnado/columna/@ancho), 
count(columnado/columna))"/></ancho>
                        </xsl:for-each>
                </xsl:variable>
            .....
        </xsl:template>

</xsl:stylesheet>

Under the interpretative Xalan, I can call this extension function ok, but 
under XSLTC it fails, this is the message I get:

javax.xml.transform.TransformerException: Cannot conver the argument/return 
value in the method call  'fcc.ima.pdf.Tbl.getAncho(real, int)'

Is this a bug?  Is XSTLC incompatible with Xalan-Java Interpretive processor?.  
I've read the doc and this can be done with both.

I'm using Xalan 2.6.0, Java 1.4.2 and used the endorsed mechanism.

Any hint will be greatly appreciated.

Regards,
     David
