Page Break "<yahp:pb />" breaks the conversion process #34

Hi,

YaHP-Converter has been working like a charm for quite sometime. Now that when I try to enhance the PDF (include page breaks in markup using "yahp:pb"), the converter fails with the below exception stacktrace,

Exception in thread "main" org.allcolor.yahp.converter.IHtmlToPdfTransformer$CConvertException: ERROR: An unhandled exception occured: null at org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer.transform(CHtmlToPdfFlyingSaucerTransformer.java:791) at org.allcolor.yahp.converter.CYaHPConverter.convertToPdf(CYaHPConverter.java:172) at PDFGenerator.generatePDFFile(PDFGenerator.java:70) at PDFGenerator.main(PDFGenerator.java:25) Caused by: java.lang.NullPointerException at org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer.transform(CHtmlToPdfFlyingSaucerTransformer.java:652) ... 3 more Destroying YAHP ClassLoader Tree

I've tried adding the page-break tag at multiple places but every time I get back the above exception stacktrace. I'm using the latest library (yahp-v1.3). Please suggest. Thanks.

Hi,

Maybe your html is invalid... at the line 652, yahp try to access the

of the page... as it is a nullpointer, seems the body is missing... that could mean you put the page break outside the body, which is invalid.

Thank you, this 'meta' tag was causing the issue,
