> I found this thread by search "invalidvalue expression". 
> Initially i was getting this exception for source list and after  implementing the workaround using object array,it was working for source list.
> And now iam getting the same exception for target list.
> I tried to use an object array for target list as well but was not able to initialize the array (i need to specify the size but in this case array size is dyamic.) 
> Please have a look at the code:
> <rich:listShuttle id="LineConfigs"
> 		sourceValue="#{bean.availableline}"
> 		targetValue="#{bean.selectedLine}" var="varaible"
> 		sourceListWidth="280" listsHeight="250" targetListWidth="280"		
> 		binding="#{bean.ShuttleList}"			
> 		converter="convertor">
> </rich:listShuttle>
>  public Object[] getAvailableLine() {
>         if (availableline== null) {
>             availableline = initialLineList.toArray();
>         }
>         return availableline ;
>     }
> public Object[] getSelectedLine() {
>         if selectedLine== null) {
> 	// how to initialize the array. as i dont have any control on the number of selected lines.?
>               }
>      return selectedLine;
