【问题描述】：
我正在使用休眠 4、spring 4、lucene 3、primefaces 5、java 7。
我有一个数据表，该数据填充在烤豆上，该表的想法是它向我显示一些未分类的单词，并让我对其进行分类。
初始表的示例看起来很正常
1 2 3 4 5
这是我的页面
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:head>
</h:head>
<h:form id="form">
<p:growl id="msgs" showDetail="true" life="2000" />
<p:dataTable id="words" var="word"
value="#{wordCatalogatorController.unknownWords}" editable="true"
style="margin-bottom:20px">
<f:facet name="header">Row Editing</f:facet>
<p:ajax event="rowEdit"
listener="#{wordCatalogatorController.onRowEdit}" update=":form:msgs" />
<p:ajax event="rowEditCancel"
listener="#{wordCatalogatorController.onRowCancel}" update=":form:msgs" />
<p:column headerText="Palabra">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{word.word}" />
</f:facet>
<f:facet name="input">
<h:outputText value="#{word.word}" />
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="Tipo Palabra">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{word.wordType}" />
</f:facet>
<f:facet name="input">
<h:selectOneMenu value="#{word.wordType}" style="width:100%"
converter="#{wordTypeConverter}">
<f:selectItems value="#{wordCatalogatorController.wordTypes}"
var="man" itemLabel="#{man.wordType}" itemValue="#{man}" />
</h:selectOneMenu>
</f:facet>
</p:cellEditor>
</p:column>
<p:column style="width:32px">
<p:rowEditor />
</p:column>
</p:dataTable>
</h:form>
</html>
这个 bean 是：
@Controller
@Transactional
public class WordCatalogatorController {
private List<Word> unknownWords = new ArrayList<Word>();
private List<WordType> wordTypes = new ArrayList<WordType>();
public WordCatalogatorController(){
//inicializamos palabras desconocidas y tipos de palabras!
for(int i = 0 ; i < 6 ; i++){
unknownWords.add(new Word("" + i));
}
for(int i = 0 ; i < 4 ; i++){
wordTypes.add(new WordType("" + i));
}
}
public void onRowEdit(RowEditEvent event) {
Word currentWord = (Word) event.getObject();
unknownWords.remove(currentWord);
}
public void onRowCancel(RowEditEvent event) {
FacesMessage msg = new FacesMessage("Edit Cancelled",
((Word) event.getObject()).getWord());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public void onCellEdit(CellEditEvent event) {
Object oldValue = event.getOldValue();
Object newValue = event.getNewValue();
if (newValue != null && !newValue.equals(oldValue)) {
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO,
"Cell Changed", "Old: " + oldValue + ", New:" + newValue);
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
然后在编辑并保存第一行 (1) 后，数据表将更新为 1 2 2 3 4 5
任何想法都会非常感激！
pojo 类的代码来了

【问题讨论】：
-
是不是和数据表中的item的id有关？
-
那里有两个嵌套表单（
form和form2）。看到这个问题：stackoverflow.com/questions/7371903/…. -
我只是做了一个更简单的测试并更新了代码，但仍然无法正常工作（这一个只有一个表格）。
-
能否提供 Word 和 WordType 类的代码？
-
您好，我正在检查，它似乎是一个 primefaces 错误，无论如何代码（我在主帖上更新）=)
