Pavel Molchanov commented on FOP-2182:
--------------------------------------

Attempt to access property pageSeq.getMainFlow() triggers NullPointerException:

{code}
                    this.pagemaster = master.getNextSimplePageMaster(
                            false, false, false, false, 
pageSeq.getMainFlow().getFlowName());
{code}

pageSeq.getMainFlow() is 'null' at this point. Actually, flows are not parsed 
at this point due to the parser logic and can't be used in internal calls.

Code in 1.0 was different. master.getNextSimplePageMaster didn't require flow 
name parameter

{code}
                    this.pagemaster = master.getNextSimplePageMaster(
                            false, false, false, false);
{code}

RTF transformation is completely broken because of this bug.
