22 Apr 2008 09:53:39,216- Thread: 13 WARNING [com.vontu.manager.admin.workflow.attributes.CustomAttributeLookup] com.
xxxxLookup not found in Loaded plugins, the plugin chain may be misconfigured or the plugin may have been unloaded.
This could happen if:
Resolution:
1. If there are duplicate entries, comment out the duplicates.
2. Check both locations for the Plugins.properties files and update them with the correct information and restart the Manager.
Example:
# Plugin Execution Chain.
# A comma-separated list of attribute lookup plug-ins to be executed in sequence.
# Example: com.vontu.lookup.script.ScriptLookup, com.vontu.lookup.xls.ExcelLookup, com.vontu.lookup.script.ScriptLookup
# This example will execute Script Lookup #1 -> ExcelLookup -> Script Lookup #2
# Even if there is only one plugin in the chain, it must be listed here.
com.vontu.plugins.execution.chain=com.vontu.lookup.script.ScriptLookup
3. Check Plugins.properties execution chain and make sure it is properly configured.
