Hi,=20

I have been trying to get a demo with Cayenne. Looks like=0ACayenne does no=
t like the schema the DAOs created are a mess. They have=0Atexts like $impo=
rtUtils.addType(${rel.TargetEntity.ClientClassName})=0Awhere you expect a m=
ethod paramter.

I was creating the following relation-ship for a magzine-subscriber managem=
ent.

(category) -|----(one to many)----<=A0 (magazines)
(magazines) -|----(one to many)----<=A0 (magazine_issues)
(magazine_issues) >----(many to one)----|-=A0 (subscribers)

basically,=0Amagazine_issues stores the information that which magazine is =
assigned=0Ato which subscriber. so, everytime a order for a magazine comes =
there=0Ais a row created in magazine_issues table.

The relationship that I have added in modeler is

category to magazine To Dep PK (checked), to many=0A (checked)

magazine to category To Dep PK (un-checked), to many (un-checked)
magazine to magazine_issues To Dep PK (checked), to many (checked)

magazine_issue to magazine To Dep PK (un-checked), to many (un-checked)
magazine_issues to subscribers To Dep PK (un-checked), to many (un-checked)

subscribers to magazine_issues To Dep PK (checked), to many (checked)

--------

with=0Athese setting now when I try to create DAOs I get lot of placeholder=
=0Asort of code like=0A$importUtils.addType(${rel.TargetEntity.ClientClassN=
ame})

Can anyone explain me what I am doing wrong here?

Thanks=20
