RE: Force page break to skip immediate next page and continue writing on third page
I eventually did manage to get by this problem. The way out was to
enforce an extent = 0 for the region body when it came to printing page
2. Also to ensure that there was always a page 2 irrespective of whether
the region body overflowed (from page 1 or not) or not was having the
force-page-count = even.

Yes. I had gone through the mailing list as well but was hoping that
this had been fixed since then. Unfortunately that does not seem to be
the case. :-(
Thanks Eric, Jeremias and Barry for all those inputs.

I found this in the mailing list archives, for what it's worth....

Well, as the error message says, FOP doesn't support that, yet. FOP
currently expects that the flow-name of the fo:flow maps to the
region-body in the simple-page-master.
If it were:
<fo:flow flow-name="xsl-region-body">
it would work.
I know this is generally possible, but I guess it is too exotic and
nobody cared to implement that possibility, yet.
Obviously no one has implemented it since then.

I ran the transform just to generate the FO and subsequently tried to
generate the pdf from that fo and found that as long as the header text
was limited and not overflowing into the next page it was doing
fine(i.e. pdf generated) but as soon as the header overflowed from page
1 ('simple') then I ran into the same error as previous...
Error: Flow 'xsl-region-body' does not map to the region-body in
page-master 'blank-page'. FOP presently does not support this.
The FO generated from the transform is below. Plz let me know if there
is something that needs to be corrected in this.

Abhishek,
I don't think you're hitting a limitation of FOP. Eric has a point. It
appears that the FO you're generating is not valid and that's why FOP
shows errors. To debug the situation I suggest you take FOP out of the
picture for the moment and just run your XSLT transformation. Then take
a look at the FO file that is generated and fix your stylesheet as
necessary. As a convenience, FOP offers to run just the XSLT
transformation on the command-line:
fop -xml my.xml -xsl my.xml -foout out.fo
It can be difficult to debug problems if you always run both the XSLT
transformation and the FO layout at the same time.
Good luck!
