Hello,

I have been fighting a little bit to create a layout for exam
(http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=exam)

So far I have a *small* layout with two styles, one for questions and
another for solutions. In the jpg attached you can see the output
generated by latex for the small example exam.lyx.

As you can see in lyx, the numbering of the questions is reseted when
a different style (solution) is inserted betwenn two questions,
howeber the latex output is numbering correctly the questions. How can
this be solved?

I'm not sure if there is a solution to this problem at present. I've seen this behavior myself, though, with other layouts, and thought there ought to be an equivalent to LaTeX's /numberwithin sort of command. I don't believe LyX has that yet, though. I'd be receptive to an enhancement request on bugzilla, though, if you want to file one. You can cc me on it, to make sure I see it. I'm guessing, in fact, that JMarc could do this pretty quickly.

(b) change the Question style from LabelType Enumerate to LabelType Counter;
(c) add 'LabelString \arabic{question}.' to the Question style;
(d) copy Style --Separator-- from stdlayouts.inc into your layout;

(f) insert a --Separator-- environment after each Question.

I'm attaching hacked copies of the layout and .lyx files.

There's a way (in LyX 1.5.6), but the cure may be worse than the disease. The solution I found is: (a) change the Question style from LatexType Command to LatexType Environment; (e) when inserting a Solution, nest it under the Question it solves; and (here comes the painful part)
