Yes serverside and Jackson will convert java objects to json and I'm trying
to pass the generated json object to clientside. I'm building a custom
implementation of modal and I'm looking to pass a JSONObject into
javascriptsupport.require.with(); This works fine if I convert the
generated json into a string then pass it into the JSONObject() like so
public JSONObject toJSON() throws IOException {
ObjectMapper mapper = new ObjectMapper();
return new JSONObject(mapper.writeValueAsString(new
Warnings(warnings)));
}
javaScriptSupport.require("warnings-modal-dialog").with(storage.getWarning().toJSON());
however that is very inefficient and if I try to do it as followed I get
the below exception
ObjectMapper mapper = new ObjectMapper();ObjectNode node =
mapper.valueToTree(pojo);
javascriptsupport.require.with(node);
JSONObject properties may be one of Boolean, Number,
String,org.apache.tapestry5.json.
JSONArray, org.apache.tapestry5.json.JSONLiteral,
I was thinking Jackson could build a json object ready to be passed to the
clientside without having to first convert it to a string then pass it into
my JSONObject. I'm trying to avoid the last two steps.
