Errors forge generated CRUD when add a child (user), to a parent (role):

1. SEVERE [javax.enterprise.resource.webcontainer.jsf.application] (default task-16) Error Rendering View[/role/create.xhtml]: java.lang.NullPointerException

2. Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Steps:

Environment/Configuration:

JBoss Developper Tool Red Hat JBoss Developer Studio / Version: 10.0.0.GA

Server: JBoss 10.0.0 WildFly

Forge version: 3.2.2 Final embeded

CDI 1.2

JSF 2.2

Two table, related one to many:

CREATE TABLE role (

role_id bigint(20) NOT NULL AUTO_INCREMENT,

name varchar(255) DEFAULT NULL,

description varchar(255) DEFAULT NULL,

createdOn TIMESTAMP DEFAULT NOW(),

createdBy varchar(255) DEFAULT NULL,

lastUpdatedOn datetime DEFAULT NULL,

lastUpdatedBy varchar(255) DEFAULT NULL,

UNIQUE (name),

PRIMARY KEY (role_id),

UNIQUE KEY role_id (role_id)

) ENGINE=Innodb AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COLLATE utf8_general_ci;

CREATE TABLE user (

user_id bigint(20) NOT NULL AUTO_INCREMENT,

users_role_id bigint(20) NOT NULL ,

fullname varchar(255) DEFAULT NULL,

password varchar(255) DEFAULT NULL,

email varchar(255) DEFAULT NULL,

username varchar(255) DEFAULT NULL,

createdOn TIMESTAMP DEFAULT NOW(),

createdBy varchar(255) DEFAULT NULL,

expireOn datetime DEFAULT NULL,

lastUpdatedOn datetime DEFAULT NULL,

lastUpdatedBy varchar(255) DEFAULT NULL,

lastAccesOn datetime DEFAULT NULL,

active bit(1) NOT NULL DEFAULT b'1',

UNIQUE (username),

PRIMARY KEY (user_id),

UNIQUE KEY user_id (user_id),

CONSTRAINT users_role_fk2 FOREIGN KEY (users_role_id) REFERENCES role (role_id)

) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COLLATE utf8_general_ci;

The next forge commands were executed:

1. project-new --top-level-package ro.procont.usersrole --named usersRole --stack JAVA_EE_7 --type war

2. jpa-setup --data-source-name usersRole --db-type MYSQL

3. jpa-generate-entities-from-tables --jdbc-url jdbc:mysql://localhost/user_role --user-name root --user-password password --driver-location /Volumes/datas/Applications/dev/jbossdevstudio10.0.0/runtimes/wildfly-10.0.0.Final/modules/system/layers/base/com/mysql/main/mysql-connector-java-5.1.33-bin.jar --hibernate-dialect org.hibernate.dialect.MySQL5InnoDBDialect --driver-class com.mysql.jdbc.Driver --database-tables *;

4. scaffold-generate --targets ro.procont.usersrole.model.* --web-root / --provider Faces;
