Error message box from COFE not showing up instead COFE crashes

[michelpons]

I am using a simple mixer Unit Operation made with the FORTRAN Unit Operation Wizard. When COLTT is not enabled on the FTNMixer Unit Operation, the calculation raises an exception for this UO and COFE displays an error message box as in the Screenshots.doc attachment.
If I am enabling COLTT v1.07 on the FTNMixer UO, COFE behaves the same as without COLTT enabled. Now with COLTT 1.08.02, COFE crashes at calculation time without displaying the error message box shown in Screenshots.doc.

I attach the log files obtained with COLTT v1.07 and v1.08.02. Fpr the FTNMixer the installatio file is too large for being attached on TRAC.

Michel,

I think it is highly likely that this issue is caused by a problem I fixed to do with the Error interfaces in the 1.08.3 development build. If so then I think it is fixed in the new build that Ahsan made today (19/10). I can't retest because the yousendit link for the FORTRAN mixer has expired. Can you retest it, or if you want to send the mixer again I can try.

Confirmed as fixed in builds after 24/10/09.

I have tested the case with COLTT 1.08.3 Build Oct 27, 2009. COFE does not crash anymore during calculation. I get now a \"Solve failed\" message box (see attached Screenshots311009 zipped file) that is pretty much the same as the one obtained without COLTT enabled on the FTNMixer. However, without COLTT enabled, I get in the message box the full message displayed by the FTNMixer and appearing in the log file attached, i.e. CapeUnknown error: value not set [Error code = 0], while I get some garbage when COLTT 1.08.3 is enabled. So the issue is partially fixed to my understanding.

Michel,

I think the problem is with the FTNMixer. When I run the example I get a different message to yours:

Unit <COLaNMixer_1> : Name: CapeUnknown error: value not set [Error code = 0]/f]

I think maybe the mixer is not handling BSTR string types properly and something about using COLTT makes it apparent. COLTT is not doing anything to either truncate or modify the string returned from the call to get_name.

The other thing I don't understand is why is FTNMixer returning the description when the call made is get_Name? Surely the response to get_Name ought to be just ECapeUnknownHR? Not CapeUnknown error: value not set [Error code = 0]/f]

Can you forward the source code for the mixer?

I have re-tested the case with COLTT 1.08.4: the defect remains. I have attached the corresponding log file (cofe_110609_104256.log).

I have retested this issue using COLTT 1.08.05 Build May 30, 2011. I used COFE 2.03, i.e. the latest COFE version available. I observe that COFE does not crash when COLTT is enabled on the FTNMixer and encounters an error in Calculate. Still the error message is slightly different if COLTT is used or not. Don't know if this shows anything to be concerned of though. I attach the log obtained as well as the screenshots obtained in both cases. You should be able to rerun this one on your side since you have the FTNMixer installer.
