Ville Virtanen updated TAP5-1757:
---------------------------------
Attachment: grid_volatile.patch
> Grid does not fully adhere to volatile="true"
> ---------------------------------------------
>
> Key: TAP5-1757
> URL: https://issues.apache.org/jira/browse/TAP5-1757
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Reporter: Ville Virtanen
> Attachments: grid_volatile.patch
>
>
> Tapestry omits the state saving of the grid if volatile parameter is set to
> true. However, grid still invokes the prepare datasource during form postback
> even though it is (when volatile is true) unneccassary. It also prevents us
> from using grid under some ajax circumstances with form.
> The proposed patch simply changes the parameter "volatile" of gridrows to be
> promoted as grid's parameter, and the gridrows inherits it. Now that Grid has
> the knowledge of the parameter it is trivial to add it to the if that checks
> whether the grid is inside form or not (when adding the setupdatasourceevent
> to formsupport).
