It is my understanding that you can "hide" custom attributes by no
longer displaying them in the various displays, but you cannot either
delete or change the type of a custom attribute because there may be
instances of that custom attribute in the repository.

Process team: please provide a correction if I got that wrong.

In RTC 2.0.0.2, eclipse client, I wanted to change several custom

Configuration GUI doesn't let me change the type of a custom
attribute, I went into the Process Configuration Source and made the
change manually. Seemed to work when I went back into the Attributes
listing, but in the Editor Presentation, it complained that I couldn't
display a Boolean attribute as an enumeration.

So, now, I tried to delete one of the custom attributes and start
over. The attribute is definitely gone from the Custom Attributes
list, and also does not appear in the Process Configuration source.
However, the GUI does not allow me to add a new attribute with the
same id, telling me that an attribute with the same id already
exists.

Lesson learned: don't muck with the source file. At this point, is
there any way I can recover these, short of creating new attributes
with slightly different id's?

I do not have a correction to that.
Perhaps someone from the Work Items team can give some guidance here. Is there a way to "unhide" a custom attribute? Will re-creating it in the source fix up the problem?

Correct, don't muck with the source javascript:emoticon(':wink:')

We do not yet support to delete or change the type of a custom attribute.
The attribute metadata (including its ID) is stored in the repository even if you have removed the custom attribute from a work item type definition.
This is necessary because there may be work items that still use that custom attribute. But this prevents you from using the ID for a new custom attribute.

I suggest that you first restore the attribute definition for the Boolean attribute (You can use the "Show in History" context menu action in the Process Configuration Source editor to restore a previous version).
With this everything should work as before.

Then you can introduce your new enum attribute (with new ID) and a new attribute presentation. Since only new work items will have this enum attribute, consider to upgrade all existing work items (how to: http://www-01.ibm.com/support/docview.wss?rs=3488&uid=swg21372230).
With some queries and bulk actions move the Boolean data of old work items to the new enum attribute. Finally remove the Boolean attribute and the attribute presentation.

hope that helps,
