String becomes array of single character strings

[jay.l.fisher]

I'm using the following code to send a simple string parameter on a DSRequest. The "groupLevel" variable is a string with the value "style".

Map<String, String> extras = new HashMap<String, String>();
extras.put("GroupLevel", groupLevel);
req.setParams(extras);

However, when I look at the request on the developer console I can see that is has been broken into an array or map of single character strings, with a mysterious integer showing up in the last array element.

"params":{
        "GroupLevel":{
            "0":"s", 
            "1":"t", 
            "2":"y", 
            "3":"l", 
            "4":"e", 
            "tI":2
        }

I remember seeing this sort of thing before and I think it was a bug in core GWT, but I can't find my previous post and can't remember what the trick was to "fix" it.

Here's the GWT issue. Please star it if you haven't already done so.

The workaround it to cast the string object to String rather than calling toString() on it.

Hi,

i had the same problem, solved by using (String)something.getValue(), instead of something.getValue().toString()
