In a template I use Tools.Outline.Numbering to create numbering for headings 
by associating different styles with different levels of the outline.

However, these style assignments are 'forgotten' in the template itself and in 
any daughter documents, if the template doesn't actually contain, in its 
boilerplate text, any instances of those heading levels.

This issue has been experienced by several other users on a range of different 
platforms and versions - several threads in the users list on the topic, but I 
couldn't find a reference to it in the zilla database - apologies if I missed 
it. For me I know the issue occurs on at least OOo 1.1Beta, 1.0.1, and 1.0.2

This issue may share common cause in part with a distinct outline numbering 
problem in templates which arises when a numbering style (with an outline 
structure) is used to provide numbering in a paragraph style. The Xreference 
is issue: 12912 - the template attached there will demonstrate the problem as 
I've repeatedly defined the outline numbering style associations, but since 
the template only has level 1 headings in its boilerplate text, this is the 
only element of the outline numbering retained in any daughter documents 
created from it.

Kind Regards
