[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2858) NumberWrapper does not manage correctly Long or Short types

Shane Bryzak closed JBSEAM-2858.
--------------------------------

    Fix Version/s: 2.0.2.CR2
       Resolution: Done

You're absolutely right, I wonder how this slipped past unnoticed for so long.  I've fixed it in SVN, it will be included in the next release of Seam (2.0.2.CR2).

> The org.jboss.seam.remoting.wrapper.BeanWrapper in conjunction with org.jboss.seam.remoting.wrapper.NumberWrapper does not use setter method to set Long or Short values of a bean.
> I have coded a simple bean like this one :
> @Name(mySimpleBean)
> public class SimpleBean
> {
>   private Long id;
>   public Long getId();
>   public void setId(Long id)
>   {
>     this.id = id;
>   }
> }
> I try to call a seam WebMethod that accepts "SimpleBean" as the parameter. In the xml data sent by the browser I have a well formed <number>123456</number> (for example) but when BeanWrapper tries to unmarshall the number, it doesn't find any suitable method with the NumberWrapper.conversionScore method. Indeed this method should have return "exact" only if the parameter type of my bean setId() was Integer. But I wanted it to be Long, so I've got a "nomatch" score...
> Then BeanWrapper tries to find a direct field access, and it finds a suitable field in the javassist proxy class instead of my SimpleBean (didn't dig in it, but surely because it is the first class declaring the field in the type hierarchy) and set its value. But when I call the getId() method, it of course returns the unset id of the SimpleBean instance, not the one of the proxy class.
> This problem is quite blocking for me because I really need my field to be a Long. I've put a dirty fix for now by declaring my field Integer. With this, I get the correct value when calling SimpleBean.getId().
