Hi Mathieu,
Now it starts to be a problem for the more experienced users or developers. I
can see prevLM, which is the layout manager of an old element, is null. The old
element is a KnuthInlineBox with position = null, maybe a footnote element, but
I'm not sure.
I guess, it's somehow related to linebreaking, since setting hyphenation to
false avoids the problem.
As far as I can see, you have two options at the moment. Either disable
hyphenation for the block containing the anchor or wait for the cavalry to
arrive.
<fo:block space-before.optimum="1em" space-before.minimum="0.8em"
space-before.maximum="1.2em" hyphenate="false">
The <fo:inline font-weight="bold">
<fo:inline id="example.anchor.1"/>anchor</fo:inline> element is
empty and contributes
nothing to the flow of the content in which it occurs. It is only useful
as a target.
</fo:block>
Regards,
Georg Datterl

Hi there,
