I am having problems inserting nomenclature entries using Lyx. I enter the symbol and description, press OK, and the nomenclature entry is not made ( ie no box Nom: …) [no error messages]. I haven't worked out what triggers this ( ie sometimes insertion works, sometimes doesn't)…Its very frustrating.
I am mainly dealing with mathematical symbols so I tend to (try to) insert in formula or after formula… I feel that the problem has to do with where I place the insertion, but I haven't worked it out. Similarly I haven't got a little test file to demonstrate it
[Tex/LaTex] Lyx: fails to insert nomenclature
lyxnomenclature

Mico's suggestion to use \mid instead of | is not only for style but will fix your problem:
$E_{\left(A_i\mid B_I\right)}$
EDIT: as egreg notes, \left( and \right) do nothing as far as LaTeX is concerned here and in some cases they can add an unwanted space. I leave them here because that's what the OP has. Note that LyX renders the corresponding math differently (the left( and \right) parentheses are larger in LyX).

OK well I have "resolved" the issue. If an element of a formula is selected when you press OK, then no nomenclature inset is created/modified. if you have text selected (outside formula inset) then the text is overwritten by the nomenclature inset.
I tend to copy paste my symbols into the nomenclature box from my document and this leads to the symbols being selected (in the formula inset). If you unselect before pressing ok in nomenclature inset then everything works ok.
