Subject Proposed patch to prevent crash from malformed javascript in 2.4.0rc1
Date Wed, 06 Feb 2013 16:34:05 GMT

Dear Cordova,

We recently had a crash in iOS because we accidentally wrote this javascript…

Cordova.exec(frontPage.updatePublicationList,frontPage.Error,"MyPlugin","update-list", null);

I may have messed up the exact syntax during copy/paste/obfusticate but the essence is that
passing null for the parameters causes a crash. But it is perfectly understandable from a
javascript point of view, given that the method being called takes no parameters.

Cordova doesn't handle this well yet, at least on iOS.  Can I propose a small patch in the
iOS code to just defend against this?

Thanks and regards.
