Hi,
Yes these are the right throw and catch places.
Here is what my debug fprintf's say when I try to load file://junk.ggg that
does not exist:
[kbhend@localhost kbhend]$ cd OpenOffice.org1.0.1
[kbhend@localhost OpenOffice.org1.0.1]$ ./soffice
in detect doing the throw
caught in basedispatcher in implts_detectType
So you should be doing the same.
Since our old simple excetpion handling did not show the problem, perhaps
the issue is throwing and catching across shared library boundaries.
The thow is done in libsfx* and the catch is done in libfwk*.
Perhaps if we changed the test program into two seaparate peices and tried
the same thing (across two shared libs) we could recreate the issue
outside of OOo.
What do you think?
Kevin
