 Since a tuple is expected but a string provided, the code will merrily iterate over the characters of the string instead of the tuple elements - and that's where the single-char attribute names come from. If the commas are consistently causing you problems, try using brackets [] instead of parentheses.
+
+== I'm using formfields.FormWrapper and none of my form fields show up ==
+
+==== Problem ====
+
+You are using code similar to that documented [http://www.djangoproject.com/documentation/forms/ here], but when you put {{ form.field_name }}, you get nothing.  
+
+==== Solution ====
+
+Make sure when you create your form object, you are passing in empty '''dictionaries''', not tuples. For example:
+{{{
+    manip = things.AddManipulator()
+    form = formfields.FormWrapper(manip, {}, {})
+}}}
+
+Not:
+
+{{{
+    manip = things.AddManipulator()
+    form = formfields.FormWrapper(manip, (), ())
+}}}
+If you pass in empty tuples for data & errors, it will silently fail to insert your form fields.
