At first I assumed another utf-8 bug. But I have stepped through the
code very carefully and can't find anything wrong. My regretful (and
possibly incorrect) conclusion is that this is a bug in the control and
that for successful use you must set subitems in order.
The fact that j504 always works and j601 always crashes argues against
this theory, but I can't find any problem in the J code.
Lots of additional experiments to isolate the problem only reinforce for
me that the problem is not in the J601 code. An example that makes this
conclusion a bit clearer is to create and show the list with several
more columns and then do the oleset of subitems in immediate execution.
Do them in order and they always work. Do one out of order and it always
crashes. The J code for oleset is fairly simple and looks to be correct.
Any additional info or examples of other controls that work with 504 and
fail with 601 would be welcome.

Subject: [Jbeta] another ole crash
Here's another OLE crash. It happens when an indexed property
(SubItems) has a gap (commented below). Although the crash
occurs inside the external COM and on a different method call (view
change),
it does not happen in j504.
It happens in beta p, but was also in beta o.

Thanks for the clean examples. The bug for both picture and object is
fixed in the next beta.

Here's a script* for object error: works in j504, not in j601:
tx3=: 3 : 0
wd 'pc xp'
wd 'cc x oleautomation:MSXML2.DOMDocument'
wd 'olemethod x base createElement *root'
wd 'olemethod x base appendChild !object:.x.temp'
smoutput wd 'oleget x base xml'
wd 'psel xp; pclose;'
)
tx3''
|domain error: wd
| wd'olemethod x base appendChild !object:.x.temp'
wd'qer'
bad parameter : 0
Should be:
<root/>
I will make next one with picture.
______________________
* Also with id instead of temp: same behavior
tx4=: 3 : 0

Subject: Re: [Jbeta] ole picture/object references
There were lots of fiddly changes to OLE for J601 (mostly due to
UTF-8).
This bug is likely due to those changes. It would help me if you
could
give the simplest script that demonstrates the bug using a dead
standard
ole object that I will have on a default XP system.

Subject: [Jbeta] ole picture/object references
In j601, ole picture/object references produce errors, while they
work
in j504.
wd 'olemethod img listimages add ,,
!picture:user\classes\ole\n.ico'
|domain error: wd
| wd'olemethod '...
wd'qer'
ole - Type mismatch : 0
See more at

Are there any ole changes in j601?
