Hi,
we (want to) use MICO within a plugin for a proprietary graphics
application (Tecplot).
This plugin serves the purpose of providing an online-interface to an
object in Tecplot, that we want to transfer to our own application.
Well, with a former version of MICO (2.3.9) everything worked fine. But
it doesn't anymore with 2.3.11. I verified that all of the CORBA/MICO
code constructs actually work, so I really cannot imagine where the
problem lies here. Could be MICO as well as the other application.
Our first guess was that it would have to do with multithreading issues,
since the symptoms looked like races. E.g. sometimes the plugin gets
loaded and spits out an IOR, another time it doesn't load at all...
Can anybody offer an educated guess about whats going on here?
Thanks very much in advance,
/Markus
