Hi
I custom my property group in my_groups.cnd. But I want to delete some properties in my property group ,and register it.but some error is now ,such as
\"The following nodetype change contains non-trivial changes.Up until now only trivial changes are supported. (see javadoc for org.apache.jackrabbit.core.nodetype.NodeTypeDefDiff):org.apache.jackrabbit.core.nodetype.NodeTypeDefDiff[

what about ? can\'t I delete the registered properties?

No, actually is not possible to delete properties in a property group. You can only add new properties.
