(Binding) Forms for inheritance domain models

[Mario Schubert]

I got a problem with an inheritance domain model and the generated forms.

Here is a part of my roo log:

entity --class ~.domain.Base --abstract --inheritanceType SINGLE_TABLE
field string --fieldName created_by
field string --fieldName updated_by
field date --fieldName created_at --type java.util.Date
field date --fieldName updated_at --type java.util.Date
entity --class ~.domain.BaseUser --abstract --extends ~.domain.Base
field string --fieldName uid
entity --class ~.domain.Employee --extends ~.domain.BaseUser --testAutomatically
field string --fieldName employeenumber --notNull
field string --fieldName firstname --notNull
field string --fieldName lastname --notNull
...

Base <-- BaseUser <-- Employee

The generated forms for the Employee model includes also the abstract fields. But these fields are set automatically. If i delete these fields from the form, the values for that attributes are set "null".

Is there a way to ingnore those fields?

Thank's a lot!

Cheers
Mario

If you want these fields to be auto populated with data you need to push in the relevant controller methods and simply set the values you need there. In case you don't want some of the fields rendered in the views simply add 'render="false"' to the relevant tags in your jspx files (this works with the Roo 1.1 releases).

HTH,

Hi Stefan, thank's for your answer. My Roo version is 1.1.0.M2 [rev 0b3543e].

The problem still exists. I created a dataset of a concrete (employee) entity:

Logger output after persist :

The update:

Update.jspx:

<field:input render="false" field="created_by" ...
<field:input render="false" field="uid"...

Logger-Ouput before merge in the update action:

2010-08-20 10:14:35,159 [http-8080-2] INFO  ...web.EmployeeController - Employee: Id: 218, Version: 0, Created_by: null, Updated_by: null, Creat

The abstract attributes are still set to "null"...Is there a way to avoid that behaviour?

Thank's!
