The help content for IBM Rational Eclipse-based products may be missing, either topics in the Table of Contents, or some contextual help.
The Preferences > Help > Content page appears twice in the preferences dialog, and neither of them can be edited.
The workspace/.metadata/.log file contains an error similar to the following:
java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 2
This is caused by a corruption of a configuration file due to a formatting change.
This issue is generally found in shell-sharing scenarios where multiple Rational products are installed into the same Eclipse shell, or an upgrade of an existing product.
Resolving The Problem
- Backup and delete the following directory (see note below) and file:
- <product install folder>\configuration\com.ibm.ut.help.common
Help will now be accessible.
Note: The configuration folder may be in other locations, depending on your Operating System setup. For example, if you do not have write access to the product install folder, the settings may be in your user directory. If you have a Windows redirected profile, you may need to look at your profile location for the configuration\com.ibm.ut.help.common folder.
