Known Issue: AttributeManager Crashes with Large Bulk Attribute Changes

Issue 

The AttributeManager crashes Workbench when a large number of attributes are selected to make a bulk change, such as removing or reordering. 

Resolution

This issue has been resolved in FME 2025.0, and bulk actions will be completed successfully. 

Workaround

The AttributeManager is an all-in-one transformer that allows adding, renaming, copying, deleting, or re-ordering. Depending on your needs, the AttributeKeeper, AttributeRemover, and AttributeRenamer can achieve the same functions as the AttributeManager.
