Hi All,

I am trying to pass a parameter to the action method of a commanButton, and i can't seem to get it work, although i tried several different methods. If I work with a commandLink i can pass the variable. This is the code of the page and the controller:

<apex:page controller="test">
    <apex:form >
           <apex:commandButton action="{!action1}" value="1, 2">
               <apex:param name="param1" value="val1"/>
               <apex:param assignto="{!param2}" value="val2"/>
           </apex:commandButton>
          <apex:commandLink action="{!action2}" value="3, 4 ">
               <apex:param name="param3" value="val3"/>
               <apex:param assignto="{!param4}" value="val4"/>
           </apex:commandLink>

           <apex:commandButton onclick="clickMethod('val5')" value="5">
          </apex:commandButton>
           <apex:actionFunction action="{!action3}" name="clickMethod" >
               <apex:param name="firstParam" assignTo="{!param5}" value="" />
           </apex:actionFunction>
    </apex:form>
</apex:page>

public class test
{
     public string param2
     {
      get;
      set {param2 = value; system.debug('param2 (property) is ' + param2);}
    }
   
     public string param4
     {
      get;
      set {param4 = value; system.debug('param4 (property) is ' + param4);}
    }

     public string param5
     {
      get;
      set {param5 = value; system.debug('param5 (property) is ' + param5);}
    }
     
      public PageReference action1()
     {
           System.debug('param1 is ' + System.CurrentPageReference().getParameters().get('param1'));
        System.debug('param2 (function) is ' + param2);
        return null;
      }
    
     public PageReference action2()
     {
        system.debug('param3  is '+ System.CurrentPageReference().getParameters().get('param3')); 
        system.debug('param4 (function) is ' + param4); 
        return null;
      }
     
     public PageReference action3()
     {
        system.debug('param5 (function) is ' + param5); 
        return null;
      }
}

When I press on the "1,2" button: the set of param2 is not invoked (I dont get the debug message), but action1 does, but the two parameters are null.

When I press on the "3,4" link: the set of param4 is invoked, then action2 runs, and the parameters have the right values.

When I press on the "5" button: same behaviour as with the "1,2" button.

Can some one tell me what I am doing wrong? or is there a known bug associated with passing parameters with a command button?

Thanks,

Alon
