未从VF页面捕获的某些字段

Question

我有一个VF页面，其中有一个弹出式窗口来接受一些字段。

当我运行页面并填写字段时，我可以看到只有一些字段值被捕获，其他字段值返回为null。我交叉检查了字段名称，它们是一样的。你知道为什么会发生这种情况吗？

<apex:outputPanel id="tstpopup1">
        <apex:outputPanel styleClass="popupBackground" layout="block" rendered="{!displayPopUp}"/>
            <apex:outputPanel styleClass="custPopup" layout="block" rendered="{!displayPopUp}">
            <apex:pageblock >
                <apex:pageblocksection >
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="Project: " />
                    <apex:inputfield id="proj" value="{!AC.Project__c}" />
                    </apex:pageblocksectionitem><p/>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="Start Date: " />
                    <apex:inputfield id="sd" value="{!AC.Start_Date__c}" />
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="End Date: " />
                    <apex:inputfield id="ed" value="{!AC.End_Date__c}" />
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="C85 Project Lead: " />
                    <apex:inputfield id="pl" value="{!AC.C85_Project_Lead__c}" />
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="Daily Charge Rate of Consultant: " />
                    <apex:inputfield id="charge" value="{!AC.Daily_Charge_Rate_of_Consultant__c}" />
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="Project Role Title: " />
                    <apex:inputfield id="role" value="{!AC.Project_Role_Title__c}" />
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem >
                    <apex:outputlabel value="Overtime Allowed: " />
                    <apex:inputfield id="overtime" value="{!AC.overtime_allowed__c}" />
                    </apex:pageblocksectionitem>
                    </apex:pageblocksection>
                    <apex:commandbutton value="Assign to a New Project" action="{!assign}"   />
                    <apex:commandbutton value="Cancel" action="{!closePopup}" immediate="true" /><br/><br/><br/>
                    </apex:pageblock>
            </apex:outputPanel>

类具有以下内容：

    public Assigned_Consultant__c AC{
        get{
            if (AC == null) AC = new Assigned_Consultant__c();
            return AC;
        }
        set; 
    }


public PageReference assign()
{ 
system.debug('Role title ...........................' + AC.Project_Role_Title__c); // this is returning null
            system.debug('Day charge ...........................' + AC.Daily_Charge_Rate_of_Consultant__c); this has value filled
system.debug('overtime_allowed__c ...........................' + AC.overtime_allowed__c);  // this is returning null


         // Project_Role_Title__c
            displayPopup = false;  
            system.debug('inside assign...........................3');
            system.debug('AC.................' + AC);   

  }

本教程有点过时，但我认为它可能有助于解释与您正在尝试做的事情相关的一些问题：Tutorial: Modal Dialogs in Visualforce。

“创建一个链接或按钮来弹出一个新的Visualforce页面实际上非常简单，让这个弹出窗口位于当前页面之上也是相当容易的。当您想要在弹出窗口中收集信息并将该信息传递回启动弹出窗口的页面时，就会出现问题。”
