Julian Wood resolved TAPESTRY-2298.
-----------------------------------
Resolution: Duplicate
This is the same as TAPESTRY-2234
> Can't use the callback option of AJAX.AutoComplete, because there is no way
> to produce a quoteless value in a JSONObject
> ------------------------------------------------------------------------------------------------------------------------
>
> Key: TAPESTRY-2298
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2298
> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.12
> Environment: osx 10.5, java 1.5
> Reporter: Julian Wood
>
> If you extend Autocomplete, and override the configure method like so:
> protected void configure(JSONObject config)
> {
> config.put("callback", "myMethod");
> }
> and in my javascript I have:
> function myMethod(element, entry) {
> console.info(element);
> console.info(entry);
> return entry;
> }
> This doesn't work because myMethod is quoted in javascript, and needs to be
> unquoted:
> new AJAX.AutoComplete('provinceState', 'provinceState:menu',
> '/webapp/signup.provincestate:autocomplete',
> {"indicator":"provinceState:loader","callback":"myMethod","paramName":"t:input"});
> should be
> new AJAX.AutoComplete('provinceState', 'provinceState:menu',
> '/webapp/signup.provincestate:autocomplete',
> {"indicator":"provinceState:loader","callback":myMethod,"paramName":"t:input"});
> Note the absence of quotes around myMethod.
> So it seems I should be able to put an object into the config which returns
> an unquoted string:
> protected void configure(JSONObject config)
> {
> config.put("callback", new JSONString() {
> public String toJSONString() {
> return "myMethod";
> }
> });
> }
> However, this errors because the allowed types for the JSONObject.put method
> seem restricted to these:
> private static final Class[] ALLOWED = new Class[] { String.class,
> Boolean.class, Number.class, JSONObject.class, JSONArray.class, Null.class };
> This, despite the fact that the method JSONObject.valueToString(Object value)
> looks for an object of type JSONString.
> I can't extend JSONObject with my own toJSONString() impl, because JSONObject
> is final.
> All that is needed is JSONString.class in ALLOWED.
