Robert Meyer updated FOP-2321:
------------------------------
Attachment: patch.diff
After investigating this issue, it stems from the fact that the RTF code cannot
handle anything other than a simple-page-master reference. This is due to the
limitation of the RTF implementation we have and without adding this feature
will unfortunately remain like that. In the case of the original FO
specification file, the page-sequence is referencing a page-sequence-master
with a repeatable-page-master. The null pointer exception occurs because it
tries to read the flow object after looking up and failing to find a
simple-page-master with the master-reference provided.
I originally created a patch to warn the user if the flow was null and
recommend to changing the FO to using a simple-page-master reference in the
page-sequence-master. A side effect of this though was that it bypassed trying
to read the flow and continued to create the document successfully without it!
As such I've simply removed the warning from the patch to only create the
page-master if the flow is not null which seems to work fine. I'll apply this
patch shortly.
I've created another issue for the missing feature in RTF to support other
page-master types:
