Confused with Fop extensions, distinct.

Tue, 16 Apr 2002 07:53:37 -0700


I have tried to read the docs. I had used distinct before but not in an embedded application.

Function not supported. Is my error message.

I have inclued my stack Trace. My includes in my application. and my stylesheet.
Thanks in advance for any help you can give.

<xsl:template match="ClientHistory"> distinct used here.
