Issue

When hosting objects from EWS/Smart Connector, such as Security Expert, into EcoStruxure Building Operation (EBO), additional or mismatched object names can result in unresolved bindings and duplicate EWS IDs.

Common symptoms include: 

- Duplicate EWS IDs with different names
- Unresolved or broken bindings
- Binding loss after deleting containers

Product Line

EcoStruxure Building Operation, EcoStruxure Security Expert.

Environment

• EcoStruxure Building Operation Enterprise Server (ES)
• Security Expert
• Smart Connector Integration
• EcoStruxure Web Service (EWS)

Cause

Typical reasons for this to occur:

• Hosted object names do not match those in Security Expert.
• Deleting containers without proper renaming can cause binding loss.

Resolution

Best Practices for Future Hosting

• Always rename the hosted object in EBO before rehosting from the hardware folder.
• This ensures that existing bindings are preserved.
• Avoid hosting the entire `SecurityExpertServer` container—only host changed or new objects.

For Unbound or Irrelevant Objects:
- If objects have no bindings, naming is not critical from an EBO perspective
- Delete the container and rehost the object from the **Hardware folder**.

To Retain Existing Bindings 

1. Identify the correct object name in the Hosted Containers folder 
2. Copy the name to avoid typos.
3. Delete the duplicate object with the correct name.
4. Rename the existing EWS ID to match the copied name.
5. Save the rename
6. Verify bindings:
   1. Right-click the renamed object
   2. Select Delete
   3. Click Show References
   4. Confirm bindings are still valid.
   5. Click No to cancel deletion.
7. Repeat this process for each object (inputs, outputs, doors, etc.) that has existing bindings.
