Subject [jira] [Updated] (CB-3548) Error handling in onJsPrompt not working
Date Thu, 30 May 2013 18:13:21 GMT

     [ https://issues.apache.org/jira/browse/CB-3548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joe Bowser updated CB-3548:
---------------------------

    Priority: Major  (was: Critical)

We only should be using the JSPrompt bridge if everything else fails to work, therefore I
don't consider this a critical issue, since we should almost never use it.

> (This is a contrived scenario written to try to understand the bridging implementation)
> It seems the error handling in the onJsPrompt() bridge in CordovaChromeClient.java is
not working correctly.

>         if (reqOk && defaultValue != null && defaultValue.length() >
3 && defaultValue.substring(0, 4).equals("gap:")) {
>             JSONArray array;
>             try {
>                 array = new JSONArray(defaultValue.substring(4));
>                 String service = array.getString(0);

>                 String r = this.appView.exposedJsApi.exec(service, action, callbackId,
message);
>                 result.confirm(r == null ? "" : r);

> If JSONException occurs then my application fails and cannot recover. For example, try
below.
> {code}
> <button onclick="myFunction()">Try it</button>
> <script>
> function myFunction()
> {
> var one=prompt("test1","Harry Potter");
> var two=prompt("test2","gap: abc");
> }
> </script>
> {code}
> ---
> But if I modify the onJsPrompt code as follows then it behaves more gracefully:
> {code}
>             } catch (JSONException e) {
>                 e.printStackTrace();
>                 return false; // added
>             }
> {code}
