In the Bulk Editor, some items under 'Property Types' that I had selected will disappear after adding another object in 'Object Types'. Why does this happen?

Description:

In the CA ERwin r8 Bulk Editor, some items under 'Property Types' that were selected will disappear after adding another object in 'Object Types'. For example if you select 'Attributes' under 'Object Types', and then 'Name' and 'Null Option' in 'Property Types' as shown below:

However, if you then add 'Entities' in 'Object Types', the 'Null Option' box is removed from 'Property Types' as follows:

Why does this happen?

Solution:

This is because the items shown in 'Property Types' are the intersection of the objects selected in 'Object Types'. In the example above, the 'Null Option' is a property of 'Attributes' but not that of 'Entities'. However 'Name' is a property of both 'Attributes' and 'Entities', which is why 'Name' still shows under the 'Property Types' after 'Entities' is selected in 'Object Types'. Therefore this behavior is by design.
