如何在Tapestry5的Textfield中提交自动完成选择值？

Question

I've got a Textfield with autocomplete and zoneUpdater mixins. Based on the typed value, I call service which returns new values for the autocomplete select. So far, so good. Big problem for me is that autocomplete select doesn't submit chosen value. I want to update different zone, based on this value. The way it works now is that I have to submit the whole form and reopen again. But that's not what customer wants, it should do it on fly without submitting the form. Is there any solution for this? Thank you.

I want to update different zone, based on this value.

I 've tried to do this with your setup and actually worked but the drawback is that the value I get as the CHANGE event of the input is what the user typed (not what the user selected from the autocomplete list).

To get the value from selected from the autocomplete list (although I 've not tried it) you should use the callback parameter of prototype's Autocompleter . Take into account that in order to do this you should rewrite a new Autocompleter mixin of your own as the Tapestry's built-in autocomplete mixin is not honoring that callback parameter.

I 've also checked out the tapestry-jquery's Autocomplete mixin and although jquery's autocomplete supports a autocompleteselect event tapestry-jquery is not handling it in it's instantiation.

I 've not checked the chenille kit autocomplete mixin which maybe can help you, I really don't know.

As far as I know you should develop your own Autocomplete mixin based on any of these and add to it the selected item event functionality.
