I've created a DataTable, which works great. I'd like to define the
behavior if a property returns NULL. For instance, this column
retrieves the AuditTrain object for a given Asset:
columns.add(new PropertyColumn<Asset>(new Model<String>("Audit
Train"), "audit_train");
If the AuditTrain is NULL, I get a null-pointer exception. Ideally,
I'd like to return a column-specific string and css class. Seems that
I need to define a new IColumn.
Any pointers? Has this been done before?
Thanks,
Norman
