TWS will not pull object metadata that was changed via Saleforce UI. The specific problem is a formula field where the formula changed. It may extend to other situations as well, but I cannot get TWS to pull down the metadata with the new formula. Using Spire 14.
If find the and delete the object information from the .sfproj file, then do a Pull from Salesforce, it will restore the file to the project with the updated server version. But, this is not a sustainable solution as it means I have to know about the changes rather than rely on TWS to recognize them. I won't always know when someone else changes a formula field via the Salesforce UI.
