[Typo3] pdf_generator + Typo3.8 = Problem

[Bernhard Welzel]

Hello,

i´m trying to get pdf_generator to work - after spending a full working 
day, i checked:

- htmldoc is working perfectly. if i capture the output of gen_pdf.php 
tsfe->content, i have a perfect pdf document

as soon as i try to download the pdf, its just empty - but contains 
correct number of pages!

can *please* somebody help? i don´t know where to look, and i need this 
function (as it was working with 3.7 and i upgraded allready some time ago!)


my setup - nothing else declared:

config.metaCharset = iso-8859-1
config.removeDefaultJS = 1
config.no_cache=1

pdf_generator = PAGE
pdf_generator {
   typeNum = {$extension.pdf_generator.typeNum}
   config.pageGenScript = EXT:pdf_generator/gen_pdf.php
   config.doctype = none
   config.xhtml_cleaning = 0
   30 = CONTENT
   30 < styles.content.get
}

P = PAGE
P {
   typeNum = 0
   config.doctype = none
   config.xhtml_cleaning = 0
   30 = CONTENT
   30 < styles.content.get

110 = TEXT
110.value = printable version
110.postUserFunc = tx_pdfgenerator->makePdfLink
100.postUserFunc.target = _blank

}

- no other ext loaded besides:
