I haven't gone back to the spec or the code, but assuming 1) that an only page is also both first and last, and 2) that isOnlyPage tells the truth about the page being tested, the problem seems to be with the
if (isOnlyPage) {...} test. Shouldn't it be if (isOnlyPage) { if ( ! ( pagePosition == EN_ONLY || pagePosition == EN_FIRST || pagePosition == EN_LAST ) ) { return false; }
--- Comment #7 from Dave Gerdt <[EMAIL PROTECTED]> 2008-07-08 13:59:23 PST --- Looking for a solution to this first page/last page problem I found a potential solution written by Ken Holman [1]. I assumed because he used it (and he seems to know a little about the subject ;) ) I had found my solution. (I hadn't discovered this bug yet...) However, the solution he provides doesn't work with FOP because as Simon points out above "ConditionalPageMasterReference.isValid(isOddPage, isFirstPage, isLastPage,isBlankPage) ... says explicitly that a conditional pagemaster reference with page-position="last" is not valid for a first page." Looking at the spec [2][3] I can't see any reason why that should be the case, though I'm no expert in the spec, to be sure. Can one of the devs comment on this? As a fix, I reordered the if statement in ConditionalPageMasterReference.isValid so that the block for isLastPage comes before the block for isFirstPage and removed 'return false' when pagePosition == EN_FIRST in the isLastPage block (see code below). This appears to fix the problem, at least for Ken's test file. Anyone see where this might blow up in my face somewhere else? I ran the test suite and everything seemed to come out fine. The test case is attached.
