The exception occurs in UISelection:
| public Object getValue()
| {
| Object value = Contexts.lookupInStatefulContexts(dataModel);
| int rowIndex = ( (DataModel) value ).getRowIndex();
| return value==null || rowIndex<0 ?
| null : var + ':' + dataModel + '[' + rowIndex + ']';
| }
|
I think this should be:
| public Object getValue()
| {
| Object value = Contexts.lookupInStatefulContexts(dataModel);
| int rowIndex = value==null ? -1 : ( (DataModel) value ).getRowIndex();
| return rowIndex<0 ?
| null : var + ':' + dataModel + '[' + rowIndex + ']';
| }
|
Someone could give me a clue why this is not working? I should give up from
Tomahawk?
