I discovered that when using the LotusNotesConnector in Delete mode, the Link Criteria does not work as expected.
Example not working:
When setting the link criteria to compare a field to an integer value, it treats the integer value as a String, so that you never get a successful link criteria.
Example of the log (using formula search in the Connection setup):
To fix this, you can script the Link Criteria:
So, the script is:
ret.filter="fieldname1=" + work.fieldname2
Remember to check the "Always use Formula Search" in the Connections for the connector.
