[英]JSF <h:inputText> / <h:outputText> not rendering according to boolean value
[英]JSF do not interpret placeholder in <h:outputText value=“#{tableRow.x}” />
我将jsf,richfaces和spring混合在一起(faces backing beans = spring beans),并且我有一个带有表的jsp页面。 由于一些奇怪的原因标签
<rich:dataTable value="#{inputBean.table}" var="tableRow">
调用inputBean.getTable()方法,并使用表(列表)具有的相同数量的表行构造输出表->#{inputBean.table}被inputBean中的对象表替换。
但是当我想通过显示行X值时
<h:outputText value="#{tableRow.x}" />
页面上仅显示#{tableRow.x}
,而不显示该值。 我认为Richfaces配置正确但jsf没有配置可能是一些配置问题(h:outputText是jsf标签)
有任何想法吗? 我将衷心感谢您的帮助。 提前致谢。 页:

好的,经过花了一天的配置,我发现了错误-我使用的是richfaces 3.1.0,但使用jsf 1.2! 当我迁移到jsf 2.x之后,问题突然消失了。 我认为主要问题是新的richfaces无法与旧的jsf混合使用。
