In PRO/II 8.3 the items of the Port Collection of a Unit Operation has successively called starting at index 0 or index 1. Consequently, if the collection index starts at 1, a call to Item requesting Item 0 returns an error (0x80040501) when for example it is COUSCOUS PropertyTester UO that is used. The log file does not show any attempt by COLTT to interrogate any further the error handling methods of the Port Collection. I thought it was a general practice to do so however.

When attempting to install the 1.08 version of COLTT on a computer running Windows 7 or Vista, an error 1303 dialog occurs when attempting to install common controls to the WinSxS directory. You must then cancel the installation as it provides no option to get past the problem. Logging in as Adminstrator and/or setting compatibily mode to previous versions of Windows doesn't help. See the attached to view the error dialog.

COLTT appears to have trouble handling value which is “CapeDoubleEmpty - it crashes. For example, if a requested property (from CalcProp) is unavailable CalcProp() will set “CapeDoubleEmpty” by calling SetProp() and COLTT will crash.

Running COFE(COCO 1.16) with COLTT 1.07 or 1.06.03 enabled and Aspen CAPEOPEN 1.0(Aspen Properties 24.0):

Selected “Default” package:

Clicked on “Liquid properties”, it crashed (COFE closed). From log file you would see: MaterialObject <1> : Call to SetProp :
