Editing a created archive package or superpackage in the Infrastructure Manager - after making edits and hitting the 'OK' button after making changes it produces this error:
"Error while transferring package to central archive
Unable to open file [package name].zip"
Period character(s) "." are not allowed in package names
This problem may also be caused by other unsupported characters in the package name.
Since there is no way to edit the package once it has a period character (".") in the package name, you will have to create a new package with a name that does not contain a period, or other unsupported character, in the package name.
Attempting to rename the package manually may or may not be successful.
