Hallo

For XotclIDE I have built a Error Stack browser witch can parse
error messages (in errorInfo) a convert it to methods list.

I have following problem. Consider the example

Class TestA
TestA instproc fooA {} {
  [self] fooC
}
TestA instproc fooB {} {
  fooC
}
TestA instproc fooC {} {
   error {error from fooC}
}

TestA a
a fooA

generate following errorInfo
error from fooC
    while executing
"error {error hier}"
    (procedure "fooC" line 2)
    ::sample0 ::TestA->fooC
    invoked from within
"[self] fooC"
    (procedure "fooA" line 2)
    ::sample0 ::TestA->fooA
    invoked from within

a fooB # generate following message

error from fooC
    while executing
"error {error hier}"
    (procedure "fooC" line 2)
    invoked from within
"fooC"
    (procedure "fooB" line 2)
    ::sample0 ::TestA->fooB
    invoked from within

I the first example we have the lines
   (procedure "fooC" line 2)
    ::sample0 ::TestA->fooC
This can be good used for parsing errorInfo
I the second there are only
   (procedure "fooC" line 2)
The same bahavior is by method chains with "next" or filter methods.

Can the xotcl be changed for same dubug infos?
