Grouper Users - Open Discussion List

[Julio Polo <>]

We're running Grouper 2.2.2 and have come across this as well.  I was thinking that maybe this was caused by a faulty database export-import that was done to migrate to our current version of Grouper, but if someone else is experiencing it, maybe it's a bug.

We've always used attributeAssignOperation=assign_attr (not add_attr) and attributeAssignValueOperation=replace_values (not assign_value or add_value) for this attribute.  The bug only revealed itself after another developer team started using this attribute, and they may have strayed from those parameters (while attribute definition remained single-valued)

Since the issue only manifested itself for a particular group, we fixed it by temporarily changing the attribute definition to multi-valued, and ensuring all code used assign_attr and replace_values.  After replacing the multiple values with a single one, we changed the definition back to single-valued.

I miss-clicked on the "UiV2Main.miscellaneous" list of functions and clicked on "Instrumentation". I was promptly presented with this error msg. (and nothing else)

I understand what the error is saying. However:
        I don't know how the system came to be in this state. ( At this point, I assume due to some automated process that went sideways. )
                Is this a known bug at some patch level? Result of a failed process? (loader job? I2 Instrumentation?)
        I don't know the right way to fix this either.
                Track down where the multiple assignment(s) are remove (one? All?) them?
                Change the attribute to be multi-valued?
                What is the downside to those actions?

If more information is needed then please send gsh/sql commands/UI click paths/files to grep/etc....
        I would be glad to poke around . ( Just give me the right stick to poke with.)  :)

Thanks in advance.
