I have a roo script that creates 3 classes with roo scaffolding. The presence of the generated roo json scaffolding is field dependent. IOW, whether I get the json .aj files or not depends on the presence of data fields. I'm sure this can't be intentional.

Here's the script, there are 3 hierarchical entities, Top, Middle and Bottom, each containing a ref to the upper and a set of the lower.

Code:
project --topLevelPackage com.fish.food
dependency add --groupId org.codehaus.jackson --artifactId jackson-jaxrs --version 1.8.4
persistence setup --provider HIBERNATE --database POSTGRES --databaseName tentacles --hostName localhost --userName squid --password calamari --transactionManager 
logging setup --level DEBUG --package PERSISTENCE 
logging setup --level DEBUG --package PROJECT 
logging setup --level DEBUG --package ALL_SPRING 

entity --class ~.domain.Top
entity --class ~.domain.Middle
entity --class ~.domain.Bottom

entity --class ~.domain.Top
field string --fieldName name 
field set --fieldName middles --type ~.domain.Middle --cardinality ONE_TO_MANY

entity --class ~.domain.Middle
field string --fieldName name 
field reference --type ~.domain.Top --fieldName top --cardinality MANY_TO_ONE 
field set --fieldName bottoms --type ~.domain.Bottom --cardinality ONE_TO_MANY 
field string --fieldName description --notNull
field string --fieldName pageId --notNull

entity --class ~.domain.Bottom
field string --fieldName name
field reference --type ~.domain.Middle --fieldName middle --cardinality MANY_TO_ONE 
field string --fieldName description --notNull
field string --fieldName tags
field string --fieldName pageId --notNull

json all
web mvc json setup
web mvc json all --package ~.web
The way it stands now it generates Controller_Json.af only for Middle and Bottom entities:

Code:
Created SRC_MAIN_WEBAPP/WEB-INF/views/login.jspx
web mvc json all --package ~.web
Created SRC_MAIN_JAVA/com/fish/food/web
Created SRC_MAIN_JAVA/com/fish/food/web/MiddleController.java
Created SRC_MAIN_JAVA/com/fish/food/web/BottomController.java
Created SRC_MAIN_JAVA/com/fish/food/web/TopController.java
Created SRC_MAIN_JAVA/com/fish/food/web/BottomController_Roo_Controller_Json.aj
Created SRC_MAIN_JAVA/com/fish/food/web/MiddleController_Roo_Controller_Json.aj
Note that the .aj is missing from Top.

The thing that differentiates whether this file is generated or not is the presence/absence of:
Code:
   field string --fieldName pageId --notNull
Remove this line and there is no generated Controller_Json.af for that entity, add it and it comes back again.

I'm using the nightly 1.2 snapshot from 8/29, the 8/30 does the same thing.
