This is the error I'm getting:
[DEBUG LoadAdDataInterceptor] Loaded AdData:[EMAIL PROTECTED] [ERROR RequestCycle] Cannot format given Object as a Number java.lang.IllegalArgumentException: Cannot format given Object as a Number at java.text.DecimalFormat.format(DecimalFormat.java:480) at java.text.Format.format(Format.java:133) at org.apache.wicket.util.convert.converters.AbstractNumberConverter.conver tToString(AbstractNumberConverter.java:109) at org.apache.wicket.util.lang.PropertyResolverConverter.convert(PropertyRe solverConverter.java:84) I'm using List<SelectOption> to populate the DropDownChoice, as per the online example: http://cwiki.apache.org/WICKET/another-dropdownchoice-example-by-adam.ht ml The only change I made to SelectOption is to set the 'value' field to an Integer (which I need for my model). Anyone any ideas as to what's going on? I'm pretty sure I didn't swap the label/value pairs as the labels show up properly. Thanks, Michael
