" WARNING: Page subsequences exhausted. Using previous subsequence. "

Hi All,

   Trying to product PDF file, I get this message in the output: 
 
    " WARNING: Page subsequences exhausted. Using previous subsequence. "

   and it dipends on break-after property. 

   It works but how can I resolve this warning?

   I use break-after property in blocks. Here is my XSL:


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" >
<xsl:template match="/">
   <fo:root >
        <fo:layout-master-set>
			
              <fo:simple-page-master master-name="first" >
	   <fo:region-body   />
              </fo:simple-page-master>
		
              <fo:page-sequence-master master-name="basicP" >
	   <fo:repeatable-page-master-alternatives>
	        <fo:conditional-page-master-reference master-name="first" page-position="first" />
                   </fo:repeatable-page-master-alternatives>
              </fo:page-sequence-master>
		
        </fo:layout-master-set>
		
        <fo:page-sequence master-name="basicP">
			
             <fo:flow flow-name="xsl-region-body">
			
	   <fo:block break-after="page"  span="all" >
	         <fo:external-graphic src="file:image1.gif"  />
	   </fo:block>

                  <fo:block break-after="page"  span="all" >
	         <fo:external-graphic src="file:image2.gif"  />
	   </fo:block>

             </fo:flow>
		
        </fo:page-sequence>
	
    </fo:root> 

</xsl:template>


-Vale.
