AjaxAppender + JsonLayout

[Anonymous]

I set up log4javascript logger with the following code:

    var logger = log4javascript.getLogger();
    var appender = new log4javascript.AjaxAppender('some url");
    appender.setLayout(new log4javascript.JsonLayout(false, false));
    appender.setSendAllOnUnload(true); //default true
    appender.setThreshold(log4javascript.Level.ERROR);
    logger.addAppender(appender);
                   
    logger.error("test");

however, the JSON sent seems encoded. This is what I can read from firebug or IE dev toolbar:

    data=%5B%7B%22logger%22%3A%22%5Banonymous%5D%22%2C%22timestamp%22%3A134303868

Do you have any suggestions? (I'm using the latest production version)

How to FIX:

1) write in JsonLayout class

     this.returnsPostData = true;

2) remove the last 4 lines of code in PreparePostData to remove &layout=xx in the request body
3) change the content-type in sendRequest to

    xmlHttp.setRequestHeader("Content-Type", appender.getLayout().getContentType());

Do you notice something wrong with this patch?
