Thanks, I'll try that. Is there any particular reason why options is filtered? Is not a common case to override the options at display time? > form = TableForm(fields=[MyMultipleSelectField(name='stuff', ...), ...], ...) > > form.display(dyn_options=dict(stuff=[(x, x)..... This is another thing I don't completely understand. How to pass options to inner widgets. I can't find any good exaplanation of the mechanism in the (rough) docs. In this case, how does the form know where to 'forward' the dyn_options? It 'forward' it to all inner widgets? -- Leandro Lucarella (luca) | Blog colectivo: http://www.mazziblog.com.ar/blog/ .------------------------------------------------------------------------, \ GPG: 5F5A8D05 // F8CD F9A7 BF00 5431 4145 104C 949E BFB6 5F5A 8D05 / '--------------------------------------------------------------------' Dentro de 30 años Argentina va a ser un gran supermercado con 15 changuitos, porque esa va a ser la cantidad de gente que va a poder comprar algo. -- Sidharta Wiki --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
