My developers have a base report that is used as a class for all other reports. The base report has a datasource for some config information, which is used to populate a few text boxes. The textboxes were created in the designer, but the declarations were moved to the class. However, when a report uses this base as its parent, the textboxes show the message "An error has occurred while processing Textbox '[object name]'; the expression contains object [fieldname] that is not defined in the current context".
Data in the derived report is appearing properly, it's just the data in the parent report that is not appearing.
