Dear Bug Team!
M-x ecb-activate RET results in:
'ECB 1.91.1: Only an edit-window can be deleted!'
This is _only_ happening under XEmacs 21.5 and is reproducible with
'-vanilla'.
Le stack:
# bind (standard-output stack-trace-on-signal debug-on-signal
# stack-trace-on-error debug-on-error) (unwind-protect ...)
signal(error ("ECB 1.91.1: Only an edit-window can be deleted!"))
# bind (args datum)
cerror("ECB 1.91.1: Only an edit-window can be deleted!")
apply(cerror "ECB 1.91.1: Only an edit-window can be deleted!" nil)
# bind (args datum)
error("ECB 1.91.1: Only an edit-window can be deleted!")
# bind (debug-on-error ad-return-value force window)
delete-window(#<window on " *ECB Sources*" 0xdb8d>)
# bind (next window window)
window-reduce-to-one(#<window on " *ECB Directories*" 0xce19>)
# bind (window)
window-reduce-to-one(#<window 0xdb89>)
# bind (combination-start root-window frame)
frame-reduce-to-one-window(#<x-frame "emacs" 0x1356>)
# bind (configuration frame)
really-set-window-configuration(#<x-frame "emacs" 0x1356>
I do not know what this `really-set-window-configuration' and why it tries to
"reduce to one window" and therefore deleting some of current windows. I do
not use XEmacs 21.5!
But what i can say is: Using `set-window-configuration' in ECB is a somehow
and probably very unused feature and should IMHO be removed because really
unnecessary. But Kevin, another developer of ECB, wants this feature - at
least he has wanted it some time ago - i will asked him if we can removed this
stuff.
Even we do not remove this call we can call it conditionally only if an ECB
users really want using this feature - which will be disabled by default.
Another remark: The error comes from an advice for `delete-window' which is
needed by ECB to work correct! This advice has to be activated during ECB
runtime but if this is a problem we could call `set-window-configuration' by a
wrapper which temporally disables the ECB-advices - but i general this is not
a really good idea and i would not do this if not really necessary.
OK, maybe Mike can better answer why really-set-window-configuration tries to
delete-windows and why this is necessary. Then we can decide how to fix the
problem and also who is fixing it, Mike or i ;-)
Ciao
Klaus
