On the ClearCase admin screen, you can specify include/exclude rules for VOBs or UCM projects. You can use a comma separated list of patterns. Each pattern is either a plain string or a regular expression.

There are multiple issues:

• the patterns aren't trimmed, so using a comma followed by a space will result in strings not being matched.
• when using a plain string, it is currently testing whether the string is part of the VOB/UCM project pattern. For example, the pattern '/vobs/myvob' not only matches vob:/vobs/myvob, but also vob:/vobs/myvob2.
• the strings being matched are the VOB/UCM Project name prefixed by 'vob:' of 'project:'. The use of the prefix is a bit awkward when specifying inclusion/exclusion rules

suggestions:

1. trim()
2. Use exact matching on the full path of the vob/project, with vob:/project: prefix removed on both sides, so it is optional in the UI
