在UML设计中加入:

1) Create the attribute with the type String
2) Set the persistence mapper to StringAsMemo

在ECOSPACE中改变属性:

Now in the app (which is db dependant)

1) On the PersistenceMapper in my app I expand the SqlDatabaseConfig
property
2) Click the [...] editor on the PersistenceMappers property
3) Click Add
4) Name = StringAsMemo
5) Mapper = Borland.Eco.Persistence.SqlServer.SqlClient.StringAsText

============================================

Attribute:

Description: Text
PMapper = StringAsNText
Allow Null = true
set the length to -1. 

in the PersistenceMapper.SqlDataConfig.PersistenceMapper I added:

Name : StringAsNText
Mapper: Borland.Eco.Persistence.Interbase.StringAsBdpBlob
