Urgent Problem with SelectLists in a controller extension

 

Hi all,

 

I have a page that has an extension class, and whenever I try to update a variable in the extension from a SelectList, it just doesn't happen.

 

Page snippet:

<apex:page standardController="Opportunity" extensions="SelfEnrollController" action="{!getParameters}" id="SelfEnrollPage">

<apex:form id="SelfEnrollForm">
...
<b>Primary Category:</b> 
<apex:SelectList id="Positions" value="{!strPrimryCatId}"  size="1" multiselect="false">
<apex:selectOptions value="{!CategoryItems}"/>
</apex:SelectList> <br/>

...

 

 

Controller snippet:

 

public  class SelfEnrollController {
Public String strPrimryCatId{get;set;}
public void getParameters() {
...
Public List<SelectOption> getCategoryItems() {
 List<SelectOption> options = new List<SelectOption>();

   for(jsonPrimaryCategories  c :cloneCategory) {
     System.debug('c.Id: ' + c.Id + ', c.Value: ' + c.Value);
     options.add(new SelectOption (c.Id,c.Value));
     }
   return options;
   }    
}



Do I have to do anything different becayse the selectlist is updating a value in an extension?

 

Help?

Hi Khaiwong

 

Just to follow-up.... I got my problem fixed, but it still seems strange.

 

I build my selection list much like I stated in my original post:

 

 <apex:SelectList value="{!strMOPId}" size="1" onChange="callUpdate()" multiselect="false">
    <apex:selectOptions value="{!theXMOPItems}"/>
 </apex:SelectList> <br/>
 

 

But I added the "onChange" javascript, which is as follows;

 

<script>
 function callUpdate(){
     updateCategory('abc');
     }     
</script>

...

<apex:actionFunction name="updateCategory" action="{!updateMOP}" rerender="zzz"/>

 

,...Where the "{!updateMOP}" doesn't do much at all, and there is no "zzz" ID to rerender -

For the life of me, I don't know what's going on....

 

I was just hoping that posting the solution might help explain what the problem I'm having is...

Hi,

 

Looks OK to me.

What's in your getParameters() method?

Hi Khaiwong,

 

Really, just a bunch of initialization stuff I pull out of the opportunity id that's pased to the page:

 

 

  public void getParameters() {        
         internalTest = false;    //DEBUG
         
         Opportunity_id  = ApexPages.currentPage().getParameters().get('Id');
         System.debug('Opportunity_id: ' + Opportunity_id  );
         strListingId= ApexPages.currentPage().getParameters().get('ListingId');
         strCID = ApexPages.currentPage().getParameters().get('customerId');
         strPrimryCatDesc = ApexPages.currentPage().getParameters().get('PrimaryCatDesc');                 
         
         strImageURL = 'HTTPS://' + ApexPages.currentPage().getHeaders().get('Host');
         strImageURL = strImageURL.replace('visual', 'content');   // problem with VF vs. Live
         
         strImageURL  += '/servlet/servlet.FileDownload?file=';
         strAdImageURL = strImageURL;   // Ad Image
         strProfileImageURL = strImageURL;   // ... Image

         theNetworkSuppression = 'Y';
         theAddressSuppression = 'Y';
         theMeterType = '1';

         if(bIsTest)
             strJSON = '{"status":"SUCCESS","primaryTags":[{"id":3748,"value":"Real Estate Sales & Services"},{"id":3849,"value":"Shopping"},{"id":4334,"value":"Wholesalers"}],"messages":[]}';
         else
             strJSON = EncodingUtil.urlDecode(ApexPages.currentPage().getParameters().get('JSON'), 'UTF-8');
         
         System.debug('JSON PASSED: ' + strJSON);
         System.debug('Opportunity ID: ' + Opportunity_id);

         // TODO: -- FIRST:  Get All the required Opportunity Info
         // Problems:   Pricebook entries???

Really nothing related... but it's necessary for the progtam to run..... but it doesn;t touch the "strPrimryCatId " variable....
