Illegal view ID from String on actionSupport call

Hi guys and gals,

 

I am trying to wrap my head around actionSupport calls within VisualForce, and I keep getting this error:

java.lang.IllegalArgumentException: Illegal view ID

 

I scoured the web, various SFDC entries, and I still can't figure out why this error is happening. Any help would be greatly appreciated.

 

Thanks!

-Jeff

<apex:page StandardController="Case" extensions="VistaCaseExtension">

            <apex:outputText value="Click Me!" />
            <apex:actionSupport event="onclick"  action="{!myTest}" rerender="counter2" status="refreshstatus" />

Change you code as follows:

 

<apex:page StandardController="Case" extensions="VistaCaseExtension">
    <apex:form>
        
        
        <apex:outputPanel id="counter">
            <apex:outputText value="Click Me!" />
            <apex:actionSupport event="onclick"  action="{!myTest}" rerender="counter2" status="refreshstatus" /> 
        </apex:outputPanel>  
        
        <apex:actionStatus id="refreshstatus" startstyle="color:green;" startText="Refreshing...."></apex:actionStatus>
          
        <apex:outputPanel id="counter2">
            <p>
            <apex:outputText value="{!testRet}" />
            </p>
        </apex:outputPanel> 
              
    </apex:form>
    
</apex:page>

Change your code to

    public void myTest(){
        system.debug('Test');
        //return testRet;
    }
or 
     public PageReference myTest()
     { 
         return null; 
     }

Nice! Thanks guys. :)

 

S91084, this did the trick!

 

 

I was wondering, what was happening for the error to occur?

 

Thanks again,

Hi,

 

      For a action method the return type can be void or it can return a PageReference not other data types like String.

Thanks a lot! That helps me grasp this better. :)
