[jira] Commented: (TAP5-138) Add Zone parameter to Select component

["Francois Armand (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637807#action_12637807 ] 

Francois Armand commented on TAP5-138:
--------------------------------------

Perhaps the use case should be even more generic than for select only, and be a mixin that take as parameter a zone and an even and does the zone update when the event occurs. 

Moreover, in your use case, I think that there will be some tricky point with the availability of the FormSupport: I'm not sure that today, you can update a zone inside a form if the zone contains fields. Si perhaps there is another bug (or perhaps it's just missing documentation) to enable partial update of a form (I suspect that FormFragment / FormInjector will have a role to play here).

> Add AJAX ability to selection in a Select component to allow the classic chaining of Select components.
> Eg. for filtering car advertisements:  3 Select components - Brand, Make, Model.  Choosing a Brand causes the Make to be enabled, showing the possible makes.  Similarly, choosing a Make causes the Model to be enabled, showing the possible models.
