for an iterated face.

usually the function is put in face/pane. but "face/pane: reduce[:iter-func]" 
works too AFAIK., that would crash 'into-widget because "tabbed? 
child" would now call it.

nothing fancy in my screen

but thats a theoretical possibility. the code does not look like 
it.

that's not Ashley's code ..

that was added by someone else to allow tabbing out of group-boxes

is the error always in 'into-widget ? Or could it be indirect recursion 
and we have to look somewhere else too?

its not the cvs-version?

svn..

Isn't it?

That's where i got it from.

ok. i read "its not ashleys code", thought its from somewhere else.

Yes, it is in the svn

just talking to Cyphre on icq - he will look into problem - he thinks 
there is overall problem with iterator in rebgui ... he tried to 
fix inside/outside drop-list parameter, so now it works, but in outside 
mode it looses hilite .... he will look into it, once he produces 
newer grid update for me ...

he also asks for eventual code example, if there is any, to being 
able to reproduce the problem ...

unless find [object! block!] type?/word get in face 'pane [      
       ; [che] -- An iterated faces may of course be tabbable, too. 
I don't handle this case for now, though.  

            return none                                                      
               ; [che]

        ]                                                                
               ; [che]

how does this code work?

looks in the pane and allows only object! and block!. on other things 
it returns none. especially on functions, thats why it uses 'get.

needs to be rewritten to be a non recursive function

or perhaps to pass the recursion count so it can exit gracefully...

its called from 'next-field too. That recurses too. looks a bit suspicious 
to me at first read. but then the error-m,essage should sometimes 
show it and not always bail out on 'into-widget IMHO.

the face-tree is recursive, so is the function.

and back-field

WHat looks suspicious is: it goes thru the parent-face. but it does 
not exclude the current face.

any quick fixes you can  suggest ?

** Internal Error: Stack overflow
** Where: into-widget
** Near: unless find [object! block!] type?/word get
** Press enter to quit...

Got it again.

it happened after I returned to the window after closing another 
window down.

Maybe

         unless wrap [siblings: find/tail siblings face]                  
                
->

  either wrap [siblings: head remove find siblings ]  [siblings: find/tail 
  siblings face]
but that is guessing

either wrap [siblings: head remove find siblings face]  [siblings: 
find/tail siblings face]

Maybe I need to make sure I set the focus when I return to the window

needs copy..

either wrap [siblings: head remove find copy siblings face]  [siblings: 
find/tail siblings face

getting closer to reproducing it

resetting focus would be worth a try. or unfocus.

5 steps to reproduce

* Internal Error: Stack overflow
** Where: tabbed?
** Near: all [find tabbed face/type face]
** Press enter to quit...

Sorry, different message now

still stack-overflow. filled by lots of 'into-widget or whatever.

Try this .. download http://www.compkarori.com/emr/synapse.exe

click on the server button.

This pops up a VID window .. enter some text and then "Accept"

Now shift tab ..and boom!!!

need to reboot windows. cu

The problem appears to be that no widget has focus

yet the shift-tab key is processed as though there is ....

Rebol []

do %rebgui.r
user: "Guest"

display "Test" compose/deep [
	field (user) return
	field return
	radio-group data [ 2 1 2 3 ] return

 button "Server" [ inform layout [ field "Type here" button "OK" [ 
 hide-popup ]]]
]
do-events

1. Highlight the first text field
2. Click on the "server" button
3. Highlight the "type here" field to give focus
4. Click on the "OK" button
the rebgui no longer has focus.
Now do tab .. and it crashes with a stack overflow.

posted to Cyphre on icq ...

Yep, reproducible.

The radio-group is redundant to the example.  You can remove it.
