"Canvas does not allow drawing" on requesting PDF from webtier

edited October 2005 in Server
I'm writing an ASP.NET application using the webtier to create Report
Builder reports.I'm using the webtier COM sample from this newsgroups.

I managed to get the parameters from my ASP.NET webform to the report
server, the report is created as expected. I'm using the rsWebAdapterPDF to
create a print button, the report server is using the ppPDFDevice unit. But
when I click this button I get an error "Canvas does not allow drawing".

The PDF is created in the cache folder (see below) but Adobe Reader is
unable to open the document because it's an empty PDF. The report itself
was created fine. When I take the URL to create the report and change the
"content=pdf" part to "content=viewer" I get my report back as expected, so
my URL resolves OK.

I'm using Delphi 2005 ASP.NET for the web part and Delphi 2005 Win32 for
the COM DLL and the report server. Report Builder version is 9.02.

Am I missing something?

Marcel van Beuzekom
