How to add values from a custom object in columns?

 

I get aresult but that is not usable:

I see 2 columns and 3 rows but the values are something like: 

 "core.apexpages.el.adapters.ApexObjectValueELAdapter@1083cd2"

 

 It must be because i put {!c} as value for the columns.

I want to put {!c.k} and {!c.n} in as values but then i get the error "MyCompanies.k does not exist"

 

- what do i have to do to display the elements "k" and "n" in the columns?

- is my construction for the "companies" OK?

 


This is my Controller

 

public class myController {

     public class myCompanies{
       string k;
       string n;
     }

     public List<myCompanies> companies {get;set;}
     myCompanies mc; 
     
     // fired when the search button is clicked  
     public PageReference search() {  

        if (companies == null) {  
            companies = new List<myCompanies>(); // init the list if it is null  
        } else {  
           companies.clear(); // clear out the current results if they exist  
        } 
         
        string mykey;
        string myname;

        for (integer i = 0; i < 3; fragment++){
              mykey=string.valueof(i);
              myname='name'+string.valueof(i);
             
              mc=null;
              myCompanies mc = new myCompanies();

              mc.k = mykey;
              mc.n = myname;
              companies.add(mc);  
              
              //system.debug('TEST: ' + companies[i].k);
        }
       
 
         return null;  
     }      
}
 
and this is the VF-page
 
<apex:page controller="myController" tabStyle="Account">
     <apex:form >  
         <apex:pageBlock mode="edit" id="block">  
  
             <apex:pageBlockSection >  
                 <apex:pageBlockSectionItem >  
                     <apex:panelGroup >  
                     <apex:commandButton value="Search" action="{!search}" rerender="block" status="status"/><p />
                     <apex:actionStatus id="status" startText="Searching... please wait..."/> 
                     </apex:panelGroup>  
                 </apex:pageBlockSectionItem>  
             </apex:pageBlockSection>  
   
              
             <apex:pageBlockSection title="Search Results" id="resultsBlock" columns="1">  
                 <apex:pageBlockTable value="{!companies}" var="c" rendered="{!NOT(ISNULL(companies))}">
                     <apex:column value="{!c}" headerValue="Key" />
                     <apex:column value="{!c}" headerValue="Name" />
                 </apex:pageBlockTable>
             </apex:pageBlockSection>  
             


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

I think you are correct in what you are doing..
 
Just try the following.. 
<apex:column headerValue="Key" > <apex:outputtext value="{!c.k}"/> </apex:column>



PleasePlease
when i try that, i still get the error: unknown property MyCompanies.k
