The qooxdoo qx.lang.Json class is actually a wrapper around either the
built-in JSON stringify and and parse methods, or a pure JavaScript
implementation. It sounds like Prototype may mucking with the toJSON()
methods used by the native JSON.stringify.
You can try explicitly setting use of the pure JavaScript implementation.
The following, issued after qx.lang.Json has completed loading (e.g., in
your main() method), should do it:
var jsonImpl = new qx.lang.JsonImpl();
qx.lang.Json.stringify = jsonImpl.stringify;
qx.lang.Json.parse = jsonImpl.parse;
Note that the JavaScript implementation is intended for use when the
browser does not natively support JSON. It will likely be considerably
slower than the native implementation if you are stringifying or parsing
large objects.
If Prototype is in fact modifying some object's toJSON() method, then this
won't fix the problem, because the pure JavaScript implementation
implements those as well. An alternative solution is to use Prototype's
JSON stringify and parse method. To do so, instead of setting
qx.lang.Json.stringify/parse to be qooxdoo's jsonImpl.stringify/parse, set
them to be Prototype's functions (assuming that Prototype provides similar
static functions), or write little wrappers that you set these references
to, that call the Prototype functions in whatever format they require.
