Re: Problem decoding complex AutoBean
I'm not seeing any issue with that code and sample JSON. Here's a quick
entrypoint that I made:
@Override
public void onModuleLoad() {
IWebchatThemeConfigurationBean bean = deserializeFromJson("{\n" +
"\"themeId\": 1,\n" +
"\"name\": \"rpc\",\n" +
"\"enabled\": true,\n" +
"\"propertiesList\": [\n" +
"{\n" +
"\"id\": 1,\n" +
"\"themeConfigurationId\": 1,\n" +
"\"chatScreen\": \"chatScreen\",\n" +
"\"component\": \"header\",\n" +
"\"property\": \"text\",\n" +
"\"value\": \"HELLO\"\n" +
"},\n" +
"{\n" +
"\"id\": 3,\n" +
"\"themeConfigurationId\": 1,\n" +
"\"chatScreen\": \"chatScreen\",\n" +
"\"component\": \"background\",\n" +
"\"property\": \"color\",\n" +
"\"value\": \"rgba(0,191,255,0.5)\"\n" +
"}\n" +
"]\n" +
"}");
DomGlobal.console.log(bean.getEnabled());
DomGlobal.console.log(bean.getThemeId() + "");
DomGlobal.console.log(bean.getName());
DomGlobal.console.log(String.valueOf(bean.getPropertiesList()));
DomGlobal.console.log(bean.getPropertiesList().size() + "");
DomGlobal.console.log(bean.getPropertiesList().stream().map(IWebchatThemeConfigurationPropertyBean::getValue).collect(Collectors.joining(",
")));
}
Notice that after running your parse method, it dumps the output to the JS
console - here is the output:
true
1
rpc
[com.vertispan.draw.connected.client.FlowChartEntryPoint_IWebchatThemeConfigurationPropertyBeanAutoBean$2@1b,
com.vertispan.draw.connected.client.FlowChartEntryPoint_IWebchatThemeConfigurationPropertyBeanAutoBean$2@1c]
2
HELLO, rgba(0,191,255,0.5)
It seems to be working?
One note: if you do not actually call the properties() method, it is not
needed in the factory, since the IWebchatThemeConfigurationPropertyBean
type is already reachable from IWebchatThemeConfigurationBean.
Using GWT 2.8.2 for this test.

Re: Problem decoding complex AutoBean
Can anyone help me?
My json string is -
{
"themeId": 1,
"name": "rpc",
"enabled": true,
"propertiesList": [
{
"id": 1,
"themeConfigurationId": 1,
"chatScreen": "chatScreen",
"component": "header",
"property": "text",
"value": "HELLO"
},
{
"id": 3,
"themeConfigurationId": 1,
"chatScreen": "chatScreen",
"component": "background",
"property": "color",
"value": "rgba(0,191,255,0.5)"
}
]
}
Interfaces are -
public interface IWebchatThemeConfigurationBean { public Integer
getThemeId(); public String getName(); public Boolean getEnabled(); public
List getPropertiesList(); }
public interface IWebchatThemeConfigurationPropertyBean { public Integer
getId(); public Integer getThemeConfigurationId(); public String
getChatScreen(); public String getComponent(); public String getProperty();
public String getValue(); }
public interface ChatFactory extends AutoBeanFactory {
AutoBean theme();
AutoBean properties();
}
ChatFactory factory;
factory = GWT.create(ChatFactory.class);
IWebchatThemeConfigurationBean deserializeFromJson(String json) {
AutoBean bean =
AutoBeanCodex.decode(factory, IWebchatThemeConfigurationBean.class, json);
return bean.as(); }
in this returned bean I'm getting null propertiesList.
name, enabled, themeId are fine.

If you want that code a bit easier to read you could use a MQueryWrapper
JSO like in the AutoBean example and then write
MQueryWrapper wrapper = JsonUtils.safeEval(response.getText());
MQueryRoot root = wrapper.getMQuery();
So at the end its like: calling .as() vs. implementing JSO's by hand/via
code generation.

Ah, thank you for that little programming problem. I was missing something
when I previously looked at overlay types. Yes, they can handle nested
objects.
Assuming the same JSON structure as above, these two objects manage it:
public class MQueryField extends JavaScriptObject {
protected MQueryField() {}
public final native String getTitle() /*-{ return this.title; }-*/;
public final native String getName() /*-{ return this.name; }-*/;
public final native String getValue() /*-{ return this.value; }-*/;
}
public class MQueryRoot extends JavaScriptObject {
protected MQueryRoot() {}
public final native String getScreenName() /*-{ return this.screenname;
}-*/;
public final native JsArray getFields()
/*-{ return this.fields.field; }-*/;
}
Now reading in that same string:
JSONObject jobj = new JSONObject(JsonUtils.safeEval(response.getText()));
MQueryRoot root =
jobj.get("mquery").isObject().getJavaScriptObject().cast();
logger.log(Level.INFO, root.getScreenName());
// prints "Index Card"
logger.log(Level.INFO, "fields["+root.getFields().length()+"]");
// prints "fields[3]"
Hm… I think I prefer AutoBeans, but this is nice to know.

I output
in the host
page
and
load on the client-side at
startup,
works great and you're sure that your JSON will be understood by the end
and don't fear forgetting to update the code on one side and not the other.

Re: Problem decoding complex AutoBean
Thank you, Thomas. That worked.
I added the interface
public interface MQueryWrapper {
MQuery getMquery();
}
In BeanFactory, I changed "AutoBean mquery();" for
"AutoBean mquery();"
My onResponseReceived() now looks like
AutoBean bean =
AutoBeanCodex.decode(clientFactory.getBeanFactory(),
MQueryWrapper.class,
response.getText());
MQuery mQuery = bean.as().getMquery();
logger.log(Level.INFO, mQuery.getScreenname());
screenName = mQuery.getScreenname();
fieldList = mQuery.getFields().getField();
view.renderFields(fieldList);
Client-side this beats overlay types because it can handle nested objects
(so long as I figure out nesting). I've not tried it server-side yet, but
that looks *very* handy. However it's probably wise at this early stage to
come up with better tags than "field" and "fields" for the XML that my JSON
originates from. As more structures are added, I may have conflicts. (I
wonder if JSON's XML.toJSONObject() does some magic with namespaces...)

Re: Problem decoding complex AutoBean
You don't seem to have an AutoBean interface with a "MQuery getMquery()"
method.
The object you're parsing has only a "mquery" property, so if you look at
it as if it were an MQuery object, getScreenname and getFields would
expectedly be null.

Problem decoding complex AutoBean
I've managed a simple AutoBean with a list. Now I've a more complex one,
and I don't understand what's wrong. My get methods are returning null
though the debugger shows the object has data.
The JSON looks like this:
{
"mquery":
{
"screenname":"Index Card",
"fields":
{
"field":[
{"title":"Name", "name":"odname", "value":"*TIFF*"},
{"title":"Date", "name":"oddate", "value":""},
{"title":"Ref #", "name":"odrefnum", "value":""}
]
}
}
}
I have three interfaces:
public interface Field {
String getTitle();
void setTitle(String title);
String getName();
void setName(String name);
String getValue();
void setValue(String value);
}
public interface FieldList {
List getField();
void setField(List field);
}
public interface MQuery {
String getScreenname();
void setScreenname(String screenname);
FieldList getFields();
void setFields(FieldList fields);
}
In my bean factory, I have
public interface BeanFactory extends AutoBeanFactory {
...
AutoBean field();
AutoBean fields();
AutoBean mquery();
}
In my onResponseReceived() method, I call
AutoBean mqueryBean =
AutoBeanCodex.decode(clientFactory.getBeanFactory(),
MQuery.class, response.getText());
MQuery mQuery = mqueryBean.as();
logger.log(Level.INFO, mQuery.getScreenname());
screenName = mQuery.getScreenname();
fieldList = mQuery.getFields().getField();
view.renderFields(fieldList);
When I look at the debugger in Chrome, screenname, etc are populated (in
mQuery:this$0:data_0 there is mquery with screenename set and 3 field
objects in fields). However mQuery.getScreenname() returns null as does
mQuery.getFields().
What am I not seeing here? Could the presence of other AutoBean<>s in my
factory (beans that work) be messing me up (do I need a separate factory)?
