* The observed behavior
Inside a list item cdlatex-tab isn't considered. An example:
To circumvent emacs' fill-paragrah issue with \[ \] I prefer using a
inline math environment in a single item list. Unfortunately cdlatex
isn't considered when hitting TAB then
- $y = a_0 + a_{1[TAB]}$ .
Emacs echos "EMPTY ENTRY" instead. The same line without the leading
list item qualifier works fine. This line
$y = a_0 + a_{1[TAB]}$
results in
$y = a_0 + a_1$ .
* The reason
In org.el in org-cycle a `cond' statement dispatches is done when
TAB is pressed. The call to `org-try-cdlatex-tab' is part of
this dispatch. Before `cond' reaches this entry it reaches the
one which determines whether or not the current context is a list
item. Since this is true here, `cond' is satified and never
considers `org-try-cdlatex-tab'. The entry calls
`org-cycle-internal-local' which then emits the "EMPTY ENTRY"
message.
* What I expected
Lets considering the case that there is a sub-item.
- $y = a_0 + a_{1}$
+ foo
I expect cdlatex-tab to be tried first. If it's nothing cdlatex
can reason about, expand/collapse the list. For
- $y = a_0 + a_{1[TAB]}$
+ foo
turns into
- $y = a_0 + a_1$
+ foo
Another TAB
- $y = a_0 + a_1[TAB]$
+ foo
turns it into
- $y = a_0 + a_1$...

The attached patch what works for me. It is however the result
of a short trail'n'error session, since I'm by no means an
experienced lisp/elisp programmer.
With the patch the behavior is slightly different than usual with
lists. Before TAB cycles the list, the cursor jumps out of the
Latex fragment:
action:
- $y = a_0 + a_{1[TAB]}$
+ foo
result:
- $y = a_0 + a_1[CURSOR]$
+ foo
action:
- $y = a_0 + a_1[TAB]$
+ foo
result:
- $y = a_0 + a_1$[CURSOR]
+ foo
action:
- $y = a_0 + a_1$[TAB]
+ foo
result: emacs mumbles "SUBTREE".
action:
- $y = a_0 + a_1$[TAB]
+ foo
result:
- $y = a_0 + a_1$...

Hello,

Your patch prevents cdlatex expansion for LaTeX environments, since
point must be in a LaTeX fragment to trigger `cdlatex-tab'.
I've slightly modified your patch to repair that. Could you test it and
report back the result?
Thanks,

Subject: [PATCH] Allow cdlatex expansions at a list item
* lisp/org.el (org-try-cdlatex-tab): Don't try to expand a LaTeX
environment when at an item.
(org-cycle): Try to call `cdlatex-tab' before cycling item's
visibility, in order to catch LaTeX fragments at an item.
This patch is a slightly modified version of Maik Beckmann's work.

From what i can tell it works flawlessly.

I've pushed a close patch into master (I had forgotten to take care of
headlines case).
Thank you for your work.

I'm sorry, but I just caught a flaw. I actually remember it being the reason
why I chose to test if the point is inside a latex fragment, which then broke
cdlatex' environment completion outside of fragments. If the point is at the
beginning of a headline cdlatex-tab advances to the next word rather than
leaving it alone.
[TAB]* foo bar bazz
Some test
* [CURSOR]foo bar bazz
Some test
* [TAB]foo bar bazz
Some test
* foo bar bazz...

because I evidently didn't read your email closely enough

Sorry for the noise and thanks again.
