How to make the attributes under Downstream attributes section as readonly in BOM transformer

The requirement is to ensure that specific attributes of a WTPart are strictly read-only across all user interfaces whenever the part belongs to the Manufacturing View. This restriction must apply universally, including during standard object modification (Edit Part wizard) and within structural manipulation tools like the BOM Transformer (downstream view).

Current Progress & Technical Challenge

• Edit Part Wizard (Success): The read-only behavior was successfully implemented for the standard Edit Part wizard by creating a custom DataUtility and overriding the getDataValue() method.

• BOM Transformer (Issue): The same logic fails in the BOM Transformer's downstream view. Attempting to override getPlainDataValue() does not prevent inline editing. This occurs because the BOM Transformer relies on tree-grid components and operational descriptors (ComponentMode) that bypass standard plain text data value rendering during inline edit cycles.
