automatic update of Fieldlength in Oracledataset

[Betz]

Hello,

I have a problem with automatic update of fieldlength in an application.
I use Delphi7 and DOA 4.0.
When I change the length of a Varchar2 in the database, I have to recompile also the delphi application that uses this field and have to change the size Attribute in Oracledataset fields-editor.
I have tried to set the charactersize in TOracledictionary of the dataset to true, but this does not work.
Is there a setting in the Oracledataset that automatically update this attributes of the fields?

Thanks

This is a common problem for persistent fields. If the current data type does not match the data type at design time when the persistent field was created, the TField class will raise an exception.
