hello
i have the following problem:

this code works fine:

faces-config.xml:

<managed-bean>
 <managed-bean-name>bean</managed-bean-name>
 <managed-bean-class>package.Bean</managed-bean-class>
 <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

Bean.java:

import javax.faces.component.UIInput;
public class Bean {
 private UIInput input;

 public UIInput getInput() {
 return input;
 }

 public void setInput(UIInput input) {
 this.input = input;
 }
}

test.xhtml:

<h:form>
 <h:inputText binding="#{bean.input}"/>
</h:form>

but if i change h:inputText to any rich component, for instance, inputNumberSpinner, the "deployment failed" error occurs while deploying :

Bean.java:

import org.richfaces.component.UIInputNumberSpinner;
public class Bean {
 private UIInputNumberSpinner inputNumberSpinner;

 public UIInputNumberSpinner getInputNumberSpinner() {
 return inputNumberSpinner;
 }

 public void setInputNumberSpinner(UIInputNumberSpinner inputNumberSpinner) {
 this.inputNumberSpinner = inputNumberSpinner;
 }
}

test.xhtml:

<a4j:form>
 <rich:inputNumberSpinner binding="#{data.inputNumberSpinner}"/>
</a4j:form>

The problem occurs only with binding of rich components, without it everything is ok.
I have richfaces 3.1.2.GA. Other libraries in dependencies are the latest releases too.

what is the problem in? did anybody have it?
