Bruce Phillips commented on WW-4249:
------------------------------------
If your Action class is using Model Driven then you need to follow this
methodology for custom type convertor:
http://struts.apache.org/release/2.3.x/docs/type-conversion.html (see
section titled Applying a Type Converter to a bean or model).
In your example I changed the conversion properties file name to
MyJavaBean-conversion.properties and placed it under the same package as the
MyJavaBean.java.
In MyJavaBean-conversion.properties I changed the key to:
rectangle=com.journaldev.struts2.typeconverters.RectangleTypeConverter
I then built the .war file and ran your example under Tomcat 7. The
rectangle conversion worked correctly.
I don't think you could ever use the methodology explained at
http://struts.apache.org/release/2.3.x/docs/type-conversion.html (see section
titled Applying a Type Converter to an Action) when your Action class is using
ModelDriven. If you find a previous Struts 2 version where that did work let me
know.

> Environment: Mac OS X 10.9 and Tomcat 7
> Reporter: Pankaj Kumar
> Assignee: Bruce Phillips
> Labels: ognl, type-converter
>
> I am trying to use custom type conversion with property file for action.
> Action class is implementing ModelDriven for bean properties.
> {code:java}
> public class WelcomeAction extends ActionSupport implements
> ModelDriven<MyBean>{
> public String execute(){
> return SUCCESS;
> }
> private MyBean bean = new MyBean();
> @Override
> public MyBean getModel() {
> return bean;
> }
> }
> {code}
> Bean class is:
> {code:java}
> public class MyBean{
> private Rectangle rectangle;
> public Rectangle getRectangle() {
> return rectangle;
> }
> public void setRectangle(Rectangle rectangle) {
> this.rectangle = rectangle;
> }
> }
> {code}
> and I have WelcomeAction-conversion.properties file parallel to action class
> with converter config as:
> {noformat}
> bean.rectangle=struts2.typeconverters.RectangleTypeConverter
> {noformat}
> I tried putting key as bean, rectangle etc but its not working, its not using
> converter class.
> If i use @TypeConverter annotation or global converter then its working fine.
