contents of '''forms.py'''
{{{
class _ProcessForm(forms.ListForm):
class fields(WidgetsList):
test1 = forms.FormFieldRepeater(
id='qq',
name='ww',
label_text='lorem',
widget=forms.SingleSelectField(id='rr',
name='tt',
options=['1', '2', '3']))
test2 = forms.FormFieldRepeater(id='aa',
name='bb',
label_text='ipsum',
widget=forms.SingleSelectField(id='ff',
name='gg',
options=['a', 'b', 'c']))

ProcessForm = _ProcessForm('process')
}}}

generates

{{{

Notice the [[BR]]<li title="" '''id="process_container"''' class="even">
[[BR]] and [[BR]] <label class="fieldlabel" for="process"
'''id="process_label"'''>lorem</label>

I was building javascript-based dynamic growing repeater (because
tw.dynforms.GrowingTableForm works werid) and this was a problematic
issue. As a workaround I've created my own template for forms.ListForm,
because I've noticed that (in this template) in line 31
(id="${field.id}_container") when field.name was None, then field.id was
invalid (and field.name was None only when rendering FormFieldRepeater
(this may help somehow)
