[jira] [Closed] (TAP5-2072) Tapestry "metadata" is not added to XHR response if event handler method return JSONArray

--------------------------------------

    Resolution: Invalid

If you are returning a JSONArray, there's no place to attach the meta data. Change your code to return a JSONObject containing a JSONArray property.

> For event handlers that return JSONObject, there is an entry _tapestry in the response object that contains additional resources or inits that are to be executed before passing the actual data to the success handler function.
> When an event handler method returns JSONArray, the resulting array is passed to the client as it is.
> The actual problem I have is that I want to add an alert init to the response.
> The issue could be addressed by wrapping JSONArray responses in a JSONObject, (e.g. {_tapestry:{...}, data: [...]}) and transforming it back on the client side. Probably, for the sake of consistency, it would even be best to to that with JSONObject responses too (e.g. {_tapestry:{...}, data: {...}}).
> However, that approach would lead to the problem that ResponseWrapper.text (representing an Object) doesn't match ResponseWrapper.json (an Array). By the way, there is also a mismatch between those properties for JSONObject responses that contain a _tapestry property: it is deleted in ResponseWrapper.json but stays in place within ResponseWrapper.text.
