这是我的第一篇文章。这个网站和所有涉及的人都很棒。谢谢大家。我的问题：我有一个对话框的数据表，显示所选寄存器的信息。这工作正常。但是，如果我尝试使用对话框来修改信息，则该字段不显示信息。 Eclipse Juno 2EE，带有jsf2和Tomcat 7.0.39的Primefaces 3.5。 Java 7.0.07 64位。用于数据修改的primefaces数据表对话框

outputText字段中的数据显示正确。字段inputText id =“edtnombre”显示为空而不是名称。当然，如果我更改outputText的inputText，它就可以。
我已经为了解决方案走了过去，什么也没找到。我尝试过不同的想法，但它没有奏效。
任何人都可以帮忙吗？谢谢！
好吧。我发现了这个问题。在这种情况下，Eclipse Web浏览器无法正常工作。现在它工作正常。在数据表显示在页面中后，似乎需要一段时间才能正常工作。也许是Eclipse的一些问题。 – Augusto 2013-05-21 17:34:46
