Liferay：jsf portlet 和带有视图参数的 commandButton 导航
Liferay: jsf portlet and navigation from commandButton with view params
我正在使用 Lifreay 6.2 和 primefaces 6.0。
我有这两个简单的看法：
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>
search.xtml
<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>
这样做的目的很简单。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 return 重定向 viewId，但现在是无关紧要的。
我的问题是.. 如果我在命令按钮组件中放置 ajax=false ，一切都会按预期进行。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，它会按预期再次运行。将参数手动放在 URL 字符串中也不起作用，不管各种编码尝试等。此外，对于常规的 jsf 组件（如 here），同样的事情也会发生。在 eclipse 控制台中出现以下行：
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。

修复
您 运行 遇到了一个错误：FACES-2958。
如您所见，您可以通过使用不带 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"
