Hi All,
I use 4DV16 on windows.
I need to know the name of the method that call ON ERR CALL
("ERRORMETHOD") command, into the method "ERRORMETHOD".
Is possible?
Thanks

even if the time difference were significant (say, 0.0005 second per
install/uninstall) I would not consider is an over head. in fact I would
happily ignore it even if the delay was 1000 times worse (which I doubt),

Hi Chip, I would run some tests to find out what the impact is.
Capture the time, run the code a number of times (say 1000) and then capture
the time again. Do this with the On Err Call and without and you should get a
sense of the impact.
If your production environment runs compiled
What kind of over head is there on setting and clearing On Err Call?
If On Err Call is being set and cleared in a loop, is there a
significant overhead issue?
ex:
For($i;1;Some_Integer_Value)
on err call("Error_Handler")
do stuff which could generate error

Still a command with a bad name. Confusion with the "execute on server" method

We always install new On err call on triggers.

Ben,
Thanks for these details, that's a huge help.
Does anyone know if this is documented anywhere? For that matter, are the
"twin" processes documented anywhere? I know that they were discussed at
some Summits in the past but, well, I haven't been to a Summit in over a
decade. Too. Darn. Far.

When a method with this property checked is executed, it runs in the context of
the servers “twin” process (which isn’t really a twin, since it doesn’t really
share

Try it compiled and interpreted and see what you find - it might work
compiled. Either way, if the behavior is undefined it would be great to get
it sorted out. Error dialogs popping up on the 4D Server machine? Not good.
'execute on server' flag set then, huh.

you set up startup. The 'global' ON ERR CALL on 4D Server is for the
application process and..I don't remember...triggers? It used to depend on
compiled/interpreted and may depend on version. I don't remember off-hand
and would want to verify with
Jody,
Right, but what I'm seeing is a client side process which has an error
handler installed. Running a method with EOS an error is blocking the
server with the 4D native error handler. Even though the server has an
error handler installed. This is following the what's in the docs:

I think I know the answer to this but think I'll ask anyway.
When my server starts up in installs an error handler, ON ERR
CALL("err_log_only"). As the name implies it simply logs errors and keeps
churning.
It doesn't seem to be called when a method called by Execute on server
Great tip! I’ll check it out for sure.

Thanks for this! Very helpful! I’ve started to use it more and more nowadays.
I’m really curious how errors in 4D process tags are handled (especially in
v16). I’m having a tough time debugging these tags through the 4D Web Server in
v15. More testing needed as I didn’t realize you could use
Use it. All of the time.
If you're a long-time 4D devleloper like me, you may have started out not
using ON ERR CALL much, if at all. I can't remember why I was scared of it,
but I tended to avoid it. That all changed forever some versions back for
me (6? 6.5?)
I think that it's 4D's job to give
