LargerThanToleranceCluster topology rule

[GeoffreyJans]

I am trying to run this code, but the last line triggers an exception... Anyone has an idea why ?

Dim itfToplgRule As Geodatabase.ITopologyRule
itfToplgRule = New Geodatabase.TopologyRule
itfToplgRule.Name = "Must be larger than cluster tolerance"
itfToplgRule.TopologyRuleType = Geodatabase.esriTopologyRuleType.esriTRTFeatureLargerThanClusterTolerance

You neglect to say what the exception is! What is the error message? The moon is made of cheese or something about your geodatabase?
