无法使用单选按钮更改选项

Question

<!--Visual force page code-->

<apex:page controller="prgrm9cls"><apex:form >
<apex:pageBlock >


<apex:pageblockSection >
<apex:selectRadio value="{!paymentstatus}" id="paymentstatus">
<apex:selectOption itemValue="Credit" itemLabel="credit card" ></apex:selectOption>
<apex:selectOption itemValue="Po" itemLabel="PO"></apex:selectOption>
<apex:selectOption itemValue="Invoice" itemLabel="Invoice"></apex:selectOption>
<apex:actionSupport event="onchange" reRender="opid2" action="{!act}"/></apex:selectRadio></apex:pageblockSection>



<apex:pageBlockSection >

<apex:outputPanel id="opid2">
<apex:pageBlockSection rendered="{!cardz}" columns="1">
<apex:pageblockSectionItem >
<apex:outputLabel value="Credit Card Name"></apex:outputLabel><apex:inputText value="{!creditname}"  />
</apex:pageblockSectionItem>
<apex:pageblockSectionItem >
<apex:outputLabel value="Credit CardNumber"></apex:outputLabel><apex:inputText value="{!CardNumber}" />
</apex:pageblockSectionItem>
<apex:pageblockSectionItem >
<apex:outputLabel value="CVV"></apex:outputLabel><apex:inputText value="{!CVV}" />
</apex:pageblockSectionItem></apex:pageBlockSection>

<apex:pageBlockSection rendered="{!invoicess}">
<apex:outputLabel value="Invoice"></apex:outputLabel><apex:inputText value="{!Invoice}" />
</apex:pageBlockSection>

<apex:pageBlockSection rendered="{!pozz}">
<apex:outputLabel value="Routing Number"></apex:outputLabel><apex:inputText value="{!porder}" required="true"/></apex:pageBlockSection></apex:outputPanel>

</apex:pageBlockSection>

</apex:pageBlock>

 </apex:form></apex:page>

public class prgrm9cls {

    public String CVV { get; set; }

    public Integer CardNumber { get; set; }

    public String creditname { get; set; }

    public String porder { get; set; }

    public boolean pozz { get; set; }
 public String paymentstatus { get; set; }
    public String Invoice { get; set; }

    public boolean invoicess { get; set; }

       public boolean cardz { get; set; }

    public PageReference act() {

       if(paymentstatus == 'Credit'){
       cardz = true;
       invoicess = false;
       pozz = false;
       }
       if(paymentstatus == 'Invoice'){
       cardz = false;
       invoicess =true;
       pozz = false;
       }
       if(paymentstatus == 'po'){
       cardz = false;
       invoicess =false;
       pozz = true;
       }

       return null;
       }



    }

当我点击任何一个单选选项时，它应该会显示它的相关文本。它只执行了前两次，并且不能继续工作。

谁能解释一下这个错误是怎么造成的？

提前谢谢。

Answer 1

对不起，我找出了错误。这是由于在面板中使用了'Required‘选项所致。删除了'Routing Number‘处的该选项

<apex:outputLabel value="Routing Number"></apex:outputLabel><apex:inputText value="{!porder}" required="true"/>

解决了这个问题。

谢谢，拉文德拉，Salesforce工程师。
