Index Out of Bounds when generating alter scripts or reports
Description

Getting the error
"The application has encountereed a problem. We are sorry for the inconvenience.
List index out of bounds (-1)." error when trying to create an alter script with large amount of changes.
However, if just a few changes are specified, the script is generated.
Resolution

Workaround 1:
Generate a new SQL for the entire database instead of trying to generate alter script.
Workaround 2:
Upgrade to the latest release of Toad for Data Modeler. Similar or related issues have been fixed on a general level, so the probability of hitting such issues is very slim.
Additional Information

Note that error might also be caused by a limitation in system resource (memory). TDM can take up to a maximum of 2GB per session. If it exceeds that amount, then program crashes.
