Hi ,  
My COMBODYN2 widgets throws an exception whenever I choose an option from them.I don’t see any effect on front end but some exception appears in log.

```auto

Combo definition

```auto

 <combodyn2 valueprop="channel" validvaluesprop="validChannels" renderasfield="true">
  </combodyn2>
```

Relevant Class Codes

```auto

...
...
...
private String m_channel;
private COMBODYNValidValues m_validChannels = new COMBODYNValidValues();
...
...
...
public void init() {
...
...
        for (int i = 0; i < channels.size(); i++) {
            ChannelDM channel = (ChannelDM) channels.get(i);
            getValidChannels().addValidValue(String.valueOf(i),channel.getChannelName()); 
...
...            
       }

 public ValidValueLine[] findValidValuesForChannel()
    {
         return getValidChannels().getItems();
         
    }
...
...
```

According to developer’s guide setting render as field option to true has a disadvantage .It says “When selecting a value from the valid value list then the value is displayed with its id - not with its  
description”. As I seen it doesn’t has that disadvantage.It just works well except the “exception” thing.  
Did I missed any attributes to set or any code to do ? Any suggestions ?

Thanks .

…you require a method:

COMBODYNValidValues getValidChannels() {  
return m\_validChannels;  
}

…your getValidChannels() method seems not to return a COMBODYNVlaidValues.

Hi Bjoern ,  
Ofcourse I have that method. I just didn’t put in my code examples.
