【中文标题】Liferay:jsf portlet 和从带有视图参数的 commandButton 导航【英文标题】:Liferay: jsf portlet and navigation from commandButton with view params 【发布时间】:2017-03-09 00:06:08 【问题描述】:我正在使用带有 primefaces 6.0 的 Lifreay 6.2。
我有这两个简单的观点:
view.xhtml
<f:view xmlns="http://www.w3.org/1999/xhtml"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:head />
<f:metadata>
<f:viewParam name="fromPlace"
value="#modelBean.fromPlace" />
</f:metadata>
<h:body>
<h:form>
<p:inputText id="foo"
value="#modelBean.fromPlace" />
<p:commandButton value="submit"
action="search?faces-redirect=true&includeViewParams=true" />
</h:form>
</h:body>
</f:view>
搜索.xml
<f:view xmlns="http://www.w3.org/1999/xhtml"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:head />
<f:metadata>
<f:viewParam name="fromPlace"
value="#modelBean.fromPlace" />
</f:metadata>
<h:body>
#param.fromPlace
#modelBean.fromPlace
</h:body>
</f:view>
这样做的目标很简单。在 inputText 元素上键入一个值,单击提交按钮,然后重定向到第二页并显示结果。我有一个命令按钮的原因是我希望将来执行一些支持 bean 操作并动态返回重定向 viewId,但现在无关紧要。
我的问题是这个.. 如果我将 ajax=false 放在命令按钮组件中,一切都会按预期工作。如果我将 ajax=true 放在命令按钮组件中,当我的输入包含空格时,我会收到一个奇怪的错误 ONLY。如果它不包含空格,它将按预期再次工作。手动将参数放在 URL 字符串中也不起作用,不管各种编码尝试等。此外,使用常规 jsf 组件(如here)也会发生同样的事情。在 Eclipse 控制台中会出现以下几行:
14:42:20,856 ERROR [BridgeContextImpl:234] Illegal character in query at index 79: /test-portlet/WEB-INF/views/search.xhtml?fromPlace=123 321&_bridgeAjaxRedirect=true
java.net.URISyntaxException: Illegal character in query at index 79: /test-portlet/WEB-INF/views/search.xhtml?fromPlace=123 321&_bridgeAjaxRedirect=true
这种行为正常吗?
编辑:我使用liferayfaces.org/ 提供的原型创建了一个新的 jsf portlet 项目,然后将其作为现有的 maven 项目导入,但出现了类似的错误。
错误

【问题讨论】:
我对@987654323@ 感到非常尴尬。事实证明我没有仔细阅读你的问题。对于那个很抱歉!明天我会尝试发布一个经过更彻底研究的答案,但我会评论我的最佳猜测它会说什么。 【参考方案1】:编辑:FACES-2958 已修复为 Bridge Impl 4.1.1
和 Bridge Ext 5.0.2
。
您遇到了一个错误:FACES-2958。
如您所见,您可以使用不带 ajax 的 commandButton
来解决此问题。
p:commandButton
:
<p:commandButton value="submit"
action="search?faces-redirect=true&includeViewParams=true"
ajax="false" />
h:commandButton
:
<h:commandButton value="submit"
action="search?faces-redirect=true&includeViewParams=true" />
【讨论】:
感谢您花时间调查这个小错误,我会接受这个作为答案。如果这最终得到解决,请发表评论或更新您的答案。以上是关于Liferay:jsf portlet 和从带有视图参数的 commandButton 导航的主要内容,如果未能解决你的问题,请参考以下文章
