Thanks, it helps me a lot. So, if I understand well :
The method "call:" calls "renderContentOn" on the object passed as 
argument (WAStoreAddressEditor here). Then, the "rows" method is called 
which have to specify what fields the object want to be printed in the 
form. Finaly, a test is performed in order to know if the object 
responds to the method "render"NameOfSymbol"On". If true, this method is 
called, else a default method is.

Is that true ?

A documentation on Seaside lacks. I can't see any documentation talking 
about this, it's strange since forms are very often used in html pages.

Thanks
