How to set values of a Plone autoform in update methode with ignoreContext = True

Question

I'm trying to make a form where I'm storing values outside of the context. Storing is done and working well but now I would like the update method to fill the form on rendering process. So I'm overriding update method of the Form class that way:

def update(self):
    super(ConfigurationForm,self).update()
    form = self.request.form
    if not form:
        #We are on a rendering process
        provider = self.getProvider()
        settings = provider.get()
        #TODO: update widget values !?

settings is a dict where keys are equals to Interface fields's names.

So I have tried many ways to update widgets values:

• Using dataconverter (too much complex and don't know if this is the only way
• Updating the self.request.form dict and call again the update method
• playing with field objects

What is the good way to achieve this ? (supporting all kind of field ?)

Don't do ignoreContext. Override getContent() to return a dict instead. The dict will be used as a pseudo context.
