在我的代码中没有逻辑错误。在旧版本中,它只是 JSF
bug。根据BalusC的评论,我遵循以下步骤:
Mojarra
( jsf-api-2.2。 9.jar
, jsf-impl-2.2.10.jar
)在 JBoss AS 7.1
。请参阅此 c:forEach
循环更改为 ui:repeat
和 h:dataTable
在JSF页面中。 var
而不是索引
现在,新改变后的代码如下所示:
Index.xhtml
< h:form ID = 形式 >
< h:panelGroup id =shipmentTermsBox>
< ui:repeat value =#{postOffer.shipmentTerms}var =shipment>
< h:selectBooleanCheckbox value =#{shipment.status}>
< f:ajax event =changelistener =#{postOffer.addShipmentTermsRow(shipment)}render =:form:shipmentTermsBox/>
< / h:selectBooleanCheckbox>
< label for =stayin>#{shipment.name}< / label> <峰; br />
< h:dataTable var =shipmentRowvalue =#{shipment.shipmentRowList}>
< h:栏>
< h:selectOneMenu value =#{shipmentRow.priceChoice}>
< f:ajax event =changelistener =#{postOffer.processPriceDiffChoice(shipmentRow)}render =:form:shipmentTermsBox/>
< / h:selectOneMenu>
< / h:列>
< h:栏>
< h:panelGroup rendered =#{shipmentRow.priceEnable}>
< h:inputText value =#{shippingRow.price}>
< f:ajax />
< / h:inputText>
< / h:panelGroup>
< / h:列>
< h:栏>
< h:commandButton value =Remove>
< f:ajax event =actionlistener =#{postOffer.removeShipmentTermsRow(shipment,shipmentRow)}render =:form:shipmentTermsBox/>
< / h:commandButton>
< / h:列>
< / h:dataTable>
< h:panelGroup rendered =#{shipment.status}>
< h:commandButton value =添加更多>
< f:ajax event =actionlistener =#{postOffer.addShipmentTermsRow(shipment)}render =:form:shipmentTermsBox/>
< / h:commandButton>
< br />< br />
< / h:panelGroup>
< / ui:repeat>
< / h:panelGroup>
< / h:表格>
PostOffer.java
public void processPriceDiffChoice(ShipmentRow row){
if(row.getPriceChoice()。equals(Above Price)){
row.setPriceEnable假);
} else {
row.setPriceEnable(true);
$ b public void addShipmentTermsRow(ShipmentProxy proxy){
if(proxy.isStatus()){
proxy.getShipmentRowList()。add (new ShipmentRow());
} else {
proxy.getShipmentRowList()。clear();
$ b $ public void removeShipmentTermsRow(ShipmentProxy proxy,ShipmentRow row){
proxy.getShipmentRowList()。remove(row);
$ / code>
注意:其余的代码与上述相同。
In my project, on click of checkbox and add more button, I am trying to add one row and on click of remove button, remove exact row.
Sometimes I get wrong parameter values in controller methods. So the whole component generation logic isn't working properly.
Index.xhtml
<h:form>
<h:panelGroup id="shipmentTermsBox">
<c:forEach items="#{postOffer.shipmentTerms}" var="shipment" varStatus="shipmentCount">
OuterIndex : #{shipmentCount.index}
<h:selectBooleanCheckbox value="#{shipment.status}">
<f:ajax event="change" listener="#{postOffer.addShipmentTermsRow(shipmentCount.index)}" render="shipmentTermsBox" />
</h:selectBooleanCheckbox>
<label for="stayin">#{shipment.name} </label>
<br/>
<table border="1">
<c:forEach items="#{shipment.shipmentRowList}" var="shipmentRow" varStatus="shipmentRowCount">
<tr>
<td>
InnerIndex : #{shipmentRowCount.index}
</td>
<td>
#{shipmentRow.priceChoice}
<h:selectOneMenu value="#{shipmentRow.priceChoice}">
<f:selectItem itemValue="Above Price" itemLabel="Above Price"/>
<f:selectItem itemValue="+ (more)" itemLabel="+ (more)"/>

public void removeShipmentTermsRow(int shipmentIndex, int rowIndex) {
shipmentTerms.get(shipmentIndex).getShipmentRowList().remove(rowIndex);

this.name = name;
}
//getters and setters
}
ShipmentRow.java
public class ShipmentRow {
private String priceChoice = "Above Price";
private String price = "0";

}
Output :
What I am doing wrong? Is there any logical bug in my code?
There is no logical bug in my code. It was just JSF
bug in older version.
As per BalusC's comment, I have followed these steps :
Mojarra
(jsf-api-2.2.9.jar
,jsf-impl-2.2.10.jar
) in JBoss AS 7.1
. Refer this
c:forEach
loop to ui:repeat
and h:dataTable
in JSF page.var
instead of index
in method parameter.Now, the new changed code is looked something like this :
Index.xhtml
<h:form id="form">
<h:panelGroup id="shipmentTermsBox">
<ui:repeat value="#{postOffer.shipmentTerms}" var="shipment">
<h:selectBooleanCheckbox value="#{shipment.status}">
<f:ajax event="change" listener="#{postOffer.addShipmentTermsRow(shipment)}" render=":form:shipmentTermsBox" />
</h:selectBooleanCheckbox>
<label for="stayin">#{shipment.name} </label> <br/>
<h:dataTable var="shipmentRow" value="#{shipment.shipmentRowList}">
<h:column>
<h:selectOneMenu value="#{shipmentRow.priceChoice}">
<f:selectItem itemValue="Above Price" itemLabel="Above Price"/>
<f:selectItem itemValue="+ (more)" itemLabel="+ (more)"/>
<f:selectItem itemValue="- (more)" itemLabel="- (more)"/>
<f:ajax event="change" listener="#{postOffer.processPriceDiffChoice(shipmentRow)}" render=":form:shipmentTermsBox"/>
</h:selectOneMenu>
</h:column>
<h:column>
<h:panelGroup rendered="#{shipmentRow.priceEnable}">
<h:inputText value="#{shipmentRow.price}">
<f:ajax/>
</h:inputText>
</h:panelGroup>
</h:column>
<h:column>
<h:commandButton value="Remove">
<f:ajax event="action" listener="#{postOffer.removeShipmentTermsRow(shipment,shipmentRow)}" render=":form:shipmentTermsBox"/>
</h:commandButton>
</h:column>
</h:dataTable>
<h:panelGroup rendered="#{shipment.status}">
<h:commandButton value="Add More">
<f:ajax event="action" listener="#{postOffer.addShipmentTermsRow(shipment)}" render=":form:shipmentTermsBox"/>
</h:commandButton>
<br/><br/>
</h:panelGroup>
</ui:repeat>
</h:panelGroup>
</h:form>
PostOffer.java
public void processPriceDiffChoice(ShipmentRow row) {
if (row.getPriceChoice().equals("Above Price")) {
row.setPriceEnable(false);
} else {
row.setPriceEnable(true);
}
}
public void addShipmentTermsRow(ShipmentProxy proxy) {
if (proxy.isStatus()) {
proxy.getShipmentRowList().add(new ShipmentRow());
} else {
proxy.getShipmentRowList().clear();
}
}
public void removeShipmentTermsRow(ShipmentProxy proxy,ShipmentRow row) {
proxy.getShipmentRowList().remove(row);
}
Note : Rest of the code is same exactly mentioned in question.
