我有一个带有 incell 编辑的数据表，它可以正确显示记录，但是当我尝试编辑一行时，没有反射(reflect)更改。以下是xhtml代码:
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{scrip.companyName}"/>
</f:facet>
<f:facet name="input">
<p:inputText value="#{scrip.companyName}"/>
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="Exchange">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{scrip.exchange}"/>
</f:facet>
<f:facet name="input">
<p:selectOneMenu style="width: 150px" value="#{manageScrip.exchange}">
<f:selectItem itemLabel="nse" itemValue="nse"/>
<f:selectItem itemLabel="bse" itemValue="bse"/>
</p:selectOneMenu>
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="Brokerage Charge">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{scrip.brokerageCharge}"/>
</f:facet>
<f:facet name="input">
<p:inputText value="#{scrip.brokerageCharge}"/>
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="Options">
<p:rowEditor/>
</p:column>
</p:dataTable>
</h:form>
</h:body>
以下是托管 bean 函数:
public void updateScrip()
{
try{
Integer i=(Integer)dt.getRowKey();
String str=i.toString();
sc=(ScripMaster) dt.getRowData(str);
scripSymbol=sc.getScripSymbol();
exchange=sc.getExchange();
companyName=sc.getCompanyName();
updateScrip(i, scripSymbol, companyName, exchange,);
}catch(Exception ex){
}
}
或者我也试过:
public void updateScrip(RowEditEvent e)
{
try{
sc=(ScripMaster) e.getObject();
scripSymbol=sc.getScripSymbol();
exchange=sc.getExchange();
companyName=sc.getCompanyName();
Integer i=sc.getScripID();
updateScrip(i, scripSymbol, companyName, exchange);
}catch(Exception ex){
}
}

最佳答案
最重要的部分是缺少数据表标签。
确保“可编辑”属性设置为 true。我认为这个属性是在 3.2 版中发明的，这使得许多 onld 数据表不可编辑。
关于jsf - primefaces 3.2 数据表单元格编辑不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10561460/
