Hi Jorge, Jorge Mario G. Mazo wrote:> Hi there I''m observing a field (collection_select) but if the > collection only has one item, the observe field will not workThat''s because, with only one item in the collection, there''s no event occurring. I think you''ll have to force the event by using a blank item, maybe with ''select one'' for the text at the beginning of the collection. Check the option_from_collection_for_select documentation. You may need to modify your approach a little. It says ''you have to wrap this call in a regular HTML select tag.'' Another option would be to render your UI differently depending on the number of items in the collection. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I spent several hours tracking down odd behavior which was partly explained by this. (The other part was having an autocomplete and and observe-field on the same form element -- nasty timing issues there!) -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
