define your own captionstyle and everything works!

in the float (!) choose paragraphstyle standard instead of
captionstyle and write
\myCaption{...the captiontext ...}

myCaption is only needful for captions with special math-symbols
or special commands. counting of figure is continuing.

on the other hand it's possible to work with a trick:
run from lyx dvi-view once without your mathsymbol
\overrightarray. the dvi-output than works and every
dvi-update too, you can ignore the latex-error when you
insert now your math-symbol.

overline and tilde works because they are not build with
special commands like overrightarrow. \vec{a} works also!

LaTeX error ignored by 1.04 but not by 1.15

2000-07-31 Thread Lionel Portmann

In a figure (float) caption, I want to put within the text some math
symboles. If I use for instance an overrightarrow over even a single
letter, I get an error from Latex. With Lyx 1.04, this error was
ignored, (no grey box) and the DVI came out all right (fine for me).

document, and no DVI (bad for me). Actually, Lyx 1.04 and 1.15 write the
same Latex code, which triggers the same error.

These errors come when I use overrightarrow, overbrace, etc., but not

Latex error looks like this :

! Illegal parameter number in definition of \reserved@a.
to be read again
   \crcr
l.40 ...n isolant, soit un conducteur métalique. }

My questions are the following (I am not (yet) a Latex guru, thanks Lyx)
:
- Has anybody got the same problem.
- Is it related to a specific Latex distribution
- Is it related to a package
- Is there a workaround within Lyx 1.15
