list-item formatting in 0.92
The formatting of list-item has seemed to have changed
from 0.20.5 to 0.92. I have a list item (code
contained below) that is rending as follows in 0.92:
---------------------
|item-body (block 1)|
---------------------
------------
|item-label|
------------
---------------------
|item-body (block 2)|
---------------------
Here is what I am expecting and how 0.20.5 seemed to
work (unless something else in the port is causing
this changed behavior):
------------ ---------------------
|item-label| |item-body (block 1)|
------------ ---------------------
---------------------
|item-body (block 2)|
---------------------
How can I get my desired behavior in 0.92?
Regards,
Dave

Re: list-item formatting in 0.92

David,
the reason for the problem is a vertical overflow in the static-content.
Log output:
WARNING: static-content overflows the available area. (fo:static-content, "Header1, Header2")
It's always a good idea to look at warnings on the log even if they may
seem unrelated. You can also see now why just posting a snippet is
sometimes not enough. Always post complete examples because the actual
problem could lie elsewhere. So, if you increase the extent for
region-before, the problem vanishes. There's no real bug. It could be
said however, that some of the code in StaticContentLayoutManager and
ListItemLayoutManager could probably be improved a little to avoid these
somewhat strange results.
Some technical background for those interested as to why the problem
manifested itself as it did:
Since the content in static-content overflows, it is broken into two
parts by the breaker (same code as for page breaking). The
StaticContentLayoutManager renders the second part right under the first.
Since the breakpoint is between the block 1 and block 2 in the item-body,
the block 2 is rendered as part of the second part. It could be said
that the StaticContent should probably not render the generated parts
but rather the whole sequence in case of an overflow. Furthermore, we
could try to find out why the ListItemLayoutManager did not combine
block 1 and block2 as the element list from the label should not allow
breaking these two apart (because of the image's height).

Confirmed here. Just ran this through FOP Trunk and the area tree
seems to be a bit off...
At first, I thought it had something to do with lists in static-
content, but then discovered that if you replace the graphic in the
label with plain text, all seems fine (?)
Cheers,
Andreas

Jeremias,
I think the three enclosed files demonstrate what I am
seeing. Please place them in the same directory and
run the following command:
fop -xml Test.xml -xsl Test.xsl -pdf Test.pdf
You will see the behavior that I described earlier (I
hope). Namely:
---------------------
|item-body (block 1)|
---------------------
------------
|item-label|
------------
---------------------
|item-body (block 2)|
---------------------
Interestingly, if you change the "change-me" variable
from '1.56in' to '1.57in', I think you will see the
following behavior:
---------------------
|item-body (block 1)|
---------------------
------------ ---------------------
|item-label| |item-body (block 2)|
------------ ---------------------
Is that what you would expect? I would expect the
following:
------------ ---------------------
|item-label| |item-body (block 1)|
------------ ---------------------
---------------------
|item-body (block 2)|
---------------------
Is there a way to get my expected behavior?
Thanks again for your assistance.
Regards,
Dave

It could, yes, especially since I can't reproduce it. Maybe if you have
a full, scaled-down FO file that demonstrates it. Maybe your snippet is
just not enough to demonstrate what's going on.

Hmm, I don't see the effect you describe. The snippet renders as I would
expect.
