I try to combine multiple PDF documents into one single PDF file using plugins.pdf\_output.combinePDFDocuments(), but the generated PDF file doesn’t contain any data.  
This is the way I try to do this:

```auto
	var vFiles = new Array('C:\Documents and Settings\karel\.servoy\PDFS\220409160107.pdf', 'C:\Documents and Settings\karel\.servoy\PDFS\220409160112.pdf','C:\Documents and Settings\karel\.servoy\PDFS\220409160120.pdf')
        var vCombinePDF = plugins.pdf_output.combinePDFDocuments(vFiles);

	//get folder location
	var vHome = plugins.it2be_tools.client().userHome
	var vSeparator = plugins.it2be_tools.client().fileSeparator
	var vFileFolder = vHome + vSeparator + '.servoy' + vSeparator + 'PDFS'
	var vDateTime = utils.dateFormat(new Date(), 'ddMMyyHHmmss')
	var vFileName = 'Combine_' + vDateTime + '.pdf'
	var vFullPath = vFileFolder + vSeparator + vFileName
	var vResult = plugins.file.writeFile(vFullPath, vCombinePDF)

```

plugins.file.writeFile returns true and creates a PDF file, but this file does not contain data.  
Anybody knows what goes wrong here?

each element of the array should be of type byte , so not the path but the content

Thank you Laurian! It’s works perfectly now.
