Due to the license revocation problem we have upgraded 2 weeks ago from ALM QC 11 patch 4 to ALM QC 11patch 18.
We did have some OTA client problems (see other forum entries here) in the first days but could solve all problems.
But we have another problem:
We have a self-written subroutine in the workflow scripts which copies defects from one project to another project.
The subroutine works stable for years now.
The subroutine is used in the following context:
(1) copy defect from project A on server X to project B on server X
(2) copy defect from project C on server Y to project D on server Y
(3) copy defect from project A on server X to project D on server Y
(1) still works fine with patch 18 no error message, (2) still works fine with patch 18 no error message, (3) with patch 18 the defect is copied successfully, but after the copy process the error message "specified cast is not valid" is shown !! The error message is not shown in English but in German "Die angegebene Umwandlung ist ungueltig". Our ALM language is English, the OS client language is German. The OS on our clients is Win 7 32, IE version is 9 or 10.
Any idea why the error message is raised only if we transfer the defect from one server to another server?
The fle exception.txt has the following content:
System.InvalidCastException: Die angegebene Umwandlung ist ungültig.
