The annotation tab in the Attributes view is not accessible for feature-linked annotations based on feature classes storing NULL values in a field that should be labeled.

解决办法

There are two possible workarounds.

• Create a new feature class and set Allow Null Values to No for the labeled fields. Copy the features of original feature class with Paste Special to the newly created feature class. However, this is a lot of work for a project with multiple feature classes. For integers, the value is set to 0 by default, which is not true.
• Set a predefined value for features without a value. Filter these features out for labeling by setting a label expression with an IF statement.
