我已经建立了一个非常简单的示例来检出BootsFaces JSF库。来自BootsFaces的b:commandButton引发了异常，而来自本地JSF组件的h:commandButton没有引发异常。我不知道为什么。
这是我用于测试的xhtml：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:b="http://bootsfaces.net/ui">
<h:head></h:head>
<h:body>
<h:form id="options">
<h:inputText label="input" title="input" value="#{testBean.message}" />
<div>
<h:commandButton value="this works" action="#{testBean.submit}">
<f:ajax execute="@form" render="@all" />
</h:commandButton>
<b:commandButton value="this does not work"
ajax="true"
action="#{testBean.submit}"
process="@form" update="@all" />
</div>
<div><h:outputText value="#{testBean.message}" /></div>
</h:form>
</h:body>
</html>
辅助bean看起来像这样：
@Named("testBean")
@RequestScoped
public class TestBean {
private String msg = null;
public void setMessage(final String msg) {
this.msg = msg;
}
public String getMessage() {
return msg;
}
public void submit() {
//do some business logic here
}
}
如果我单击网页上的第一个按钮（“此方法有效”），那么一切都会按预期进行。如果我单击网页的第二个按钮（“这不起作用”），则会引发以下异常：

这是我用于测试的软件： Wildfly 14.0.1，JSF 2.3.5 SP2（Mojarra）和BootsFaces 1.4.1
有人知道为什么BootsFaces中的按钮引发此异常吗？
