Hi All,

          I have a small problem with my controller. I am trying to get values from a custom object  and trying to update the values. But it is not working fine. I have paste the visualforce code and the controller below:

<apex:page standardcontroller="Case" sidebar="false" showHeader="false" extensions="SubmitCaseController">
             
                           
       <apex:outputPanel styleClass="box1" style="border-style:none;border-widht:0px;background-color: #FFFFFF;margin-top:35px" >        
 
         <apex:outputPanel styleClass="box1" style="border:none">
    <apex:dataTable columns="2" id="firstbox1" value="{!List}" var="p" rendered="{!(List!=null)}">
        <apex:column styleClass="c1">
            <apex:outputtext value="Profile Name"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.Name}" style="width:250px"/>
        </apex:column>
        <apex:column styleClass="c1">
            <apex:outputtext value="Operating System"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.operating_system__c}" style="width:250px"/>
        </apex:column>
        <apex:column styleClass="c1">
            <apex:outputtext value="Application Development Language"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.Application_Development_Language__c}" style="width:250px"/>
        </apex:column>
        <apex:column styleClass="c1">
            <apex:outputtext value="Database"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.Database__c}" style="width:250px"/>
        </apex:column>
        <apex:column styleClass="c1">
            <apex:outputtext value="Web Server"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.Web_Server__c}" style="width:250px"/>
        </apex:column>
        <apex:column styleClass="c1">
            <apex:outputtext value="Servlet Engine"/>
        </apex:column>
        <apex:column styleClass="c2">
            <apex:inputtext value="{!p.Servlet_Engine__c}" style="width:250px"/>
        </apex:column>
         <apex:column styleClass="bbox1">
                                                     <apex:column styleClass="bbox1">
              
<apex:commandButton value="Update" action="{!Save}" />
               </apex:column>
    </apex:dataTable>               
</apex:outputPanel>    
                     </apex:outputPanel>
        </apex:form>
   </apex:outputPanel>
</apex:page>

My controller is as follows:

public abstract class SubmitCaseController {

   
    public SubmitCaseController(ApexPages.StandardController controller) {
           }
    
   public List<Customer_Profile__c> cList{get;set;}
                 
   public PageReference Save(){
             update cList;
             return null;
   }
  
    
      public List<Customer_Profile__c> getList(){     
        cList = [select Id,Name,Application_Development_Language__c,Database__c,operating_system__c,Servlet_Engine__c,Web_Server__c from Customer_Profile__c where Account__r.Name =:accName];
              return cList;
    }        
    
     }

Can anyone please help me with this issue. Thanks in advance.
