Matej Novotny commented on WFLY-11680:
--------------------------------------
bq. I will try to avoid using proxies and check if it doesn't break anything else.
You will always have a client proxy in place with request scoped beans (or any other
normal scoped bean).
The proxy is just an "empty holder" that knows how to get an actual underlying
bean and forwards all calls there.
Setting anything on a field that belongs to proxy class has no effect. Furthermore, bean
initialization is lazy - you will get a proxy object injected but actual contextual
instance isn't created until you first try to access it which might have confused you
when debugging.
bq. The reason why I assume proxies are correct is that during the injection phase it uses
client proxy with a real backed bean instance which gets the parameters set correctly via
the proxy,...
If you debug the {{PropertyInjectorImpl}} when it tries to inject into the class, the
{{Object target}} parameter is a proxy class and not the contextual instance.
Calling {{getClass().getName()}} on it will get you something like
{{org.jboss.as.test.integration.jaxrs.client.CustomBean$Proxy$_$$_WeldClientProxy}}.
jax-rs and CDI: FormParam in BeanParam is not injected
------------------------------------------------------
Key: WFLY-11680
URL:
https://issues.jboss.org/browse/WFLY-11680
Project: WildFly
Issue Type: Bug
Components: CDI / Weld, REST
Reporter: Marek Kopecký
Assignee: Ivo Studensky
Priority: Critical
RESTEasy with CDI is unable to inject FormParam in BeanParam if BeanParam is with
RequestScoped
This issue is not a regression against WF11. But this issue looks like spec violation (cc
[~msvehla]). This issue is not present on Payara with Jersey (reference jax-rs
implementation)
Example:
{code:java}
@Path("/a")
public class Resource {
@POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Integer a(@BeanParam CustomBean customBean) {
return customBean.getParam().length();
}
}
@RequestScoped
public class CustomBean {
@FormParam("param")
private String param;
public String getParam() {
return param;
}
}
{code}
{code:html}
