问题描述

我有一个应用程序在Jboss 6上使用Primefaces 3.5和Omnifaces 1.5，并使用myfaces 2.1.5

I have an application using Primefaces 3.5 with Omnifaces 1.5 on Jboss 6, using myfaces 2.1.5

在尝试使用o:converter时，出现以下错误.

on trying to use the o:converter I am getting the follow error.

org.omnifaces.taghandler.Converter

viewId=/xhtml/propelModules/initiatePropel.xhtml
location=C:\jboss-6.1.0.Final\server\default\deploy\PropelEAR.ear\PropelWeb.war\xhtml\propelModules\initiatePropel.xhtml
phaseId=RENDER_RESPONSE(6)

Caused by:
java.io.NotSerializableException - org.omnifaces.taghandler.Converter

有关代码是...

<p:selectManyCheckbox value="#{initiatePropelManagedBean.currentWon.selectedEmployeeList}" 
  layout="pageDirection">
<o:converter converterId="omnifaces.ListIndexConverter" 
      list="#{initiatePropelManagedBean.currentWon.employeeList}" />
     <f:selectItems value="#{initiatePropelManagedBean.currentWon.employeeList}"
       var="emp" itemLabel="#{emp}" itemValue="#{emp}" />
     <p:ajax process="@this" update="employeeCount"></p:ajax>
</p:selectManyCheckbox>

推荐答案

我可以重现您的问题.这是MyFaces 2.1.5中的错误.我找不到相关的错误报告和修复版本，但至少可以告诉我，使用最新的MyFaces 2.1.12，此构造对我来说很好用.因此，升级MyFaces也应该为您完成.

I can reproduce your problem. This is a bug in MyFaces 2.1.5. I can't find the associated bug report and the fix version, but I can at least tell that this construct works just fine for me with the current latest MyFaces 2.1.12. So, upgrading MyFaces should do it for you as well.

无关与具体问题无关，此处的转化策略有些奇怪.只需使用omnifaces.SelectItemsConverter或omnifaces.SelectItemsIndexConverter(如果您对Employee实体没有很好的equals())就足够了.

Unrelated to the concrete problem, the conversion strategy is here somewhat strange. Just using the omnifaces.SelectItemsConverter or omnifaces.SelectItemsIndexConverter (if you don't have a good equals() on the Employee entity) should be sufficient.

<p:selectManyCheckbox ... converter="omnifaces.SelectItemsIndexConverter">
    <f:selectItems value="#{initiatePropelManagedBean.currentWon.employeeList}" />
</p:selectManyCheckbox>

SelectItems(Index)Converter严格不需要List<SelectItem>作为模型，在视图中仅需要<f:selectItem(s)>. List(Index)Converter适用于不使用<f:selectItem(s)>的组件，例如<p:autoComplete>，<p:picklist>等.

The SelectItems(Index)Converter doesn't strictly require a List<SelectItem> as model, it only requires a <f:selectItem(s)> in the view. The List(Index)Converter is intented for components which do not use <f:selectItem(s)>, such as <p:autoComplete>, <p:picklist>, etc.

如果您由于某些原因无法升级MyFaces，这将是替代解决方案.

This would be the alternate solution if you can't upgrade MyFaces for some reason.
