Populating a Dictinoary object in GWT with data from server

Question

Hi

I'm trying to populate a Dictionary object in GWT with data from the server. The Dictionary takes a javascript as input, but I want to send in a String. (acctually its an hashmap.toString). How do I create an javascript object from my string (in java ) that Dictionary will accept?

Thanks

All you need to do is throw that data onto the response as a JS var.

For example, if you put the following var on the response:

var someVar = {
  a: "a",
  b: "b",
};

Then you can use a Dictionary to access it:

Dictionary d = Dictionary.getDictionary("someVar");
String a = d.get("a");
