Comment 3 for bug 924124

this is as far as I got with the trace back

in the portlet code in PortletSubscriptionAddForm.update() ...

> collective/dancing/browser/portlets/channelsubscribe.py(156)update()
-> super(PortletSubscriptionAddForm, self).update()
(Pdb) list
151 def newslettertool(self):
152 return getToolByName(self.context, 'portal_newsletters')
153
154 def update(self):
155 import pdb;pdb.set_trace()
156 -> super(PortletSubscriptionAddForm, self).update()
157 self.channel_id = self.context.id
158
159 if self.context.collector is not None:
160 stored_values = self.stored_values
161 collector_schema = self.context.collector.schema

self.widgets gets assigned somewhere in the super(...) call, but there is so much indirection here, I'm not able to effectively trace down the part which assigns the default value to welf.widgets["composer.email"].value

-> super(PortletSubscriptionAddForm, self).update()
(Pdb) n
