I haven't seen this issue before. The chance is little that this behaviour is browser specific. Try in different kinds of browsers to exclude the one and other (IE6/7/8, FF, Safari, Chrome, etc). The chance is bigger that this is caused by a (poor) Javascript key event listener which incorrectly suppresses the enter key (for example a JS password validator which checks the entered characters).
我以前没见过这个问题。这种行为特定于浏览器的可能性很小。尝试在不同类型的浏览器中排除一种和另一种（IE6/7/8、FF、Safari、Chrome 等）。这是由（糟糕的）Javascript 键事件侦听器错误抑制回车键（例如检查输入的字符的 JS 密码验证器）引起的可能性更大。
If still in vain, just add the following onkeypressto the h:form:
如果仍然无效，只需将以下内容添加onkeypress到h:form：
<h:form onkeypress="if (event.keyCode == 13) this.submit();">
You need to take textareas into account however. If you have them, then you need to copy all onkeypressevents over the h:inputXXXelements expectof textareas yourself.
但是，您需要考虑 textareas。如果你有它们，那么你需要自己复制所有onkeypress事件到textareas期望的h:inputXXX元素上。

If you want to press ENTER key instead of submit in any form, what we have to do here is add defaultcommand attribute in af:form tag and give id of the submit button as value. Sample code snippet for this is
如果你想按 ENTER 键而不是在任何表单中提交，我们在这里要做的是在 af:form 标签中添加 defaultcommand 属性，并给出提交按钮的 id 作为值。示例代码片段是
<af:form id="f1" defaultCommand="cb1">
<af:outputText value="User Name" id="usename"/>
<af:inputText value="#{BackingBean.userName}" id="uname" />
<af:outputText value="Password" id="pword"/>
<af:inputText value="#{BackingBean.password}" id="paword" secret="true"/>
<af:commandButton text="Submit" action="#{BackingBean.method}" id="cb1" />
</af:form>

I made it work by placing an additional inputBox and hiding it using javascript. Let me know if you have any other suggestions Thanks baluC for pointing me in the right direction Jerry

There is an old specification that pops into my mind with this one. If you have a form that contains just oneinput field, the behaviour of submitting on the enter-key doesn't work in some versions of Internet Explorer. The easiest fix is to make sure you have more than one input field.
有一个旧规范突然出现在我的脑海中。如果您的表单仅包含一个输入字段，则enter在某些版本的 Internet Explorer 中无法使用-key提交的行为。最简单的解决方法是确保您有多个输入字段。
Other reasons for this problem include...
此问题的其他原因包括...
- Not having an input of type submit
- Having an input of type submit, but it isn't visible on the page (hidden or positioned off-page)
- 没有提交类型的输入
- 有一个提交类型的输入，但它在页面上不可见（隐藏或定位在页面外）
This behaviour is very specific to this browser.
此行为非常特定于此浏览器。

From ComputerPilot's answer I came to know that it's bug in IE which wouldn't make the parent form to submit if there's only one input element. To overcome this problem I added one more input Box with attribute style="display:none"and it worked fine.
从 ComputerPilot 的回答中，我了解到这是 IE 中的错误，如果只有一个输入元素，它不会使父表单提交。为了克服这个问题，我又添加了一个带有属性的输入框，style="display:none"它运行良好。
