[Java-gnome-developer] null returned for Objects stored in a TreeStore

[Lars W. <la...@di...>]

Hi everyone,

while I don't want to be perceived as a nuisance, I just stumbled across
another problem: objects I store in a ListStore using setValue(TreeIter,
DataColumnObject, Object), are returned as null whenever I try to
retrieve them using getValue(TreeIter, DataColumnObject).

A test-case is appended below.  In my setup it's output is:
null

Is this a bug or am I doing something wrong?

Regards,
Lars

		DataColumnObject object_column = new DataColumnObject();
		
		ListStore list_store = new ListStore(new
DataColumn[]{ object_column });

		String object = "Foobar";
		
		TreeIter iter = list_store.appendRow();
		
		list_store.setValue(iter, object_column, object);
		
		System.out.println(list_store.getValue(iter, object_column));
