After a widget is created with extended SFDC credentials, when the user returns to the widget manager url to edit preferences (to "Edit" the widget), when clicking the "Custom Mappings" tab the following error appears:
"There was an error loading the object definition. It is likely that some of the login credentials for a connection were incorrect. Error details: com.boomi.model.connector.common.salesforce.SalesforceException: Error executing login. Error message received from Webservice. ERROR: sf:INVALID_LOGIN --------------- INVALID_LOGIN: Invalid username, password, security token; or user locked out."
The issue is actual intended behavior due to security reasons. When you open the Widget Manager URL to Edit preferences again, you will need to re-enter your Salesforce connection password and token and save it each time.
