Ivo Studensky commented on WFLY-11680:
--------------------------------------
[~manovotn] Thanks for your comment.
I will try to avoid using proxies and check if it doesn't break anything else.
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, the bean instance is stored into a ContextualStore, it uses the same instance
of the back bean as well as the same instance of the ProxyMethodHandler all the time. But
then when it gets to the invocation of post method -> Resource client proxy ->
Resource instance -> Bean client proxy -> Bean instance, the Bean instance is a new
one instead of the previously one used for the injection. At time of this invocation it
calls CachingContextualInstanceStrategy which creates a new instance. I expect this might
be fixed to get to the correct instance somehow instead of disabling proxies at all.
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}
