Method not found ??

[nimo22]

I have a method with a string-property:

public void methodWithParam(String test) {

.

}

<a4j:commandLink value="click" action="#{myBean.methodWithParam('mystring')}" ../>

But when using this, I get this exception:

15:04:07,981 ERROR [STDERR] Caused by: javax.el.MethodNotFoundException: /home.xhtml @151,136 action="#{myBean.methodWithParam(test)}": Method not found: [e-mail]()

15:04:07,981 ERROR [STDERR]      ... 32 more

However, I definitly have this method in my class !

The same code works in JSF 1.2 but not in JSF 2.0. When using a method without parameters, it works. What is wrong?

I found the error. I use weld and inject a bean A (which has this method) into another bean B which I referenced by @Named.

You can reproduce the error by doing these steps:

@Named

class A{

public void methodWithParam(String s){}

public void methodWithoutParam(){}

}

@Named

class B{

@Inject A injectedA:

}

Now, I reference my method within the view:

This does work:

<a4j:commandLink value="click" action="#{b.injectedA.methodWithoutParam}" ../>

This does NOT work (because it has parameters):

<a4j:commandLink value="click" action="#{b.injectedA.methodWithParam('mystring')}" ../>

But when using this, the method with parameters works:

<a4j:commandLink value="click" action="#{a.methodWithParam('mystring')}" ../>

This is very strange ! Is that a bug in weld ?

[ilya_shaikovsky]

need to check more still not looked more deeply.. but think not in Weld but at EL-evaluation at some level.

B.t.w. does it works with h:command ?

[nimo22]

It does also not work with h:commandLink. So it is not a rf-issue.

If I change bean A to a stateless ejb, the indirect call of the methodWithParam via bean B will work.

If I reference the methodWithParam directly from bean A, then it will also work.

But injecting the (non ejb) managed bean A into B (which both are session scoped beans) and calling methodWithParam indirectly via b.injectedA.methodWithParam('mystring') will definitly not work - it only works for methods without params.

When changing bean A to a stateless ejb, the indirect call of b.injectedA.methodWithParam('mystring') via bean B will work. Strange.

Hi Stephan

Have you test it with

@Named

@SessionScoped

class A.....

It can be, that in your next call, the bean is not more.

 {quote}But injecting the (non ejb) managed bean A into B (which both are session scoped beans) and calling methodWithParam indirectly {quote}

Bean A was already declared with SessionScoped.
