first page puzzle

first page puzzle

[Alan Bowen]

The following code

	\setuphead[chapter][page=yes]	
	\setuppagenumbering[alternative=doublesided]
	\setuppagenumbering[location={header, middle},state=nomarking]
	\installpagebreakhandler{last}{} 	

	\definehead[Item][title]
	\setupsectionblock[Item][number=no,page=right]
	\setuphead[Item][after={\blank[2*big]},alternative=middle,style={\tfa 
\rm}]

	\setuphead[Item][header=high,footer={}]
	\setupheadertexts[text]
		[{\sc\ItemTitle}]
		[\pagenumber]
		[\pagenumber]
		[{\it xxxxx}]

produces no header or footer on the first page, just as I want, in a  
multi-page document. What I am not seeing is why the same code  
produces a header (“ItemTitle....pagenumber”) when the document is  
only one page in length.

I realize that I can insert \setupheader[state=high] in the source  
file of my single-page documents to get what I want, but that would  
still leave me puzzled.

Any suggestions/explanations would be much appreciated.

this is related to tex's way of breaking pages; when settings change 
while tex has not yet broken a page, they get lost

  bla bla (not enough for a page)

  \setupheadertexts[x]

  bla bla 

versus:

  bla bla (not enough for a page)

  \page \setupheadertexts[x]

  bla bla

i try as good as i can to handle this but esp in border cases a user has 
to force a break before such settings that affect the 'current' of 
'next' page; it's just a matter of where/when (settings are expanded. 
not delayed)

here the problem is in:

    \installpagebreakhandler{last}{}    

if you change this to issue a (one) page break, it will probably work ok

Thanks, Hans. That is very helpful. I will do some experimenting with  
\installpagebreakhandler.

Best, Alan
