Jackson is not able to read json ChartOptions

[silvestrelosada]

Trying to read ChartOptions from json string. ChartOptions has same method name for backgroundCollor and it is causing issues.

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Conflicting setter definitions for property "backgroundColor":

How does the JSON string looks like ?

The two setters are:

public ChartOptions setBackgroundColor(final Color color) {
		this.backgroundColor = new SimpleColor(color);
		return this;
	}

	public ChartOptions setBackgroundColor(final ColorReference backgroundColor) {
		this.backgroundColor = backgroundColor;
		return this;
	}

It is interesting what is the type of the parameter Jackson constructed: Color or ColorReference.
I'd suggest to try with latest version of Jackson (2.9.8) and if it still fails then to open a bug report at Jackson. It should be possible to resolve the correct setter if the parameter type is one of those two.

That parameter was not specified the same happens with Options object and setColor.

Please paste the JSON string that use have used.

Here is an example

	public static void main(String[] args) {
		JsonRenderer render = new JsonRenderer();
		String charOptions = "{\"chart\":{\"renderTo\":\"container\",\"type\":\"bar\"},\"title\":{\"text\":\"Fruit Consumption\"},\"xAxis\":{\"categories\":[\"Apples\",\"Bananas\",\"Oranges\"]},\"yAxis\":{\"title\":{\"text\":\"Fruit eaten\"}},\"series\":[{\"name\":\"Jane\",\"data\":[1,0,4]},{\"name\":\"John\",\"data\":[5,7,3]}]}";
		Options chartOptions = render.fromJson(charOptions, Options.class);

		System.out.println(chartOptions);
	}

The json object

{  
   "chart":{  
      "renderTo":"container",
      "type":"bar"
   },
   "title":{  
      "text":"Fruit Consumption"
   },
   "xAxis":{  
      "categories":[  
         "Apples",
         "Bananas",
         "Oranges"
      ]
   },
   "yAxis":{  
      "title":{  
         "text":"Fruit eaten"
      }
   },
   "series":[  
      {  
         "name":"Jane",
         "data":[  
            1,
            0,
            4
         ]
      },
      {  
         "name":"John",
         "data":[  
            5,
            7,
            3
         ]
      }
   ]
}```

And this is the exception

Caused by: java.lang.IllegalArgumentException: Conflicting setter definitions for property "colors": de.adesso.wickedcharts.highcharts.options.Options#setColors(1 params) vs de.adesso.wickedcharts.highcharts.options.Options#setColors(1 params)

Much better example case, Im generating an options object, then Im serializing it into json string and then I'm trying to read it, It also fails.

	public static void main(String[] args) {
		JsonRenderer render = new JsonRenderer();
		Options options = new Options();

	    options
	        .setChartOptions(new ChartOptions()
	            .setType(SeriesType.LINE));

	    options
	        .setTitle(new Title("My very own chart."));

	    options
	        .setxAxis(new Axis()
	            .setCategories(Arrays
	                .asList(new String[] { "Jan", "Feb", "Mar", "Apr", "May",
	                    "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" })));

	    options
	        .setyAxis(new Axis()
	            .setTitle(new Title("Temperature (C)")));

	    options
	        .setLegend(new Legend()
	            .setLayout(LegendLayout.VERTICAL)
	            .setAlign(HorizontalAlignment.RIGHT)
	            .setVerticalAlign(VerticalAlignment.TOP)
	            .setX(-10)
	            .setY(100)
	            .setBorderWidth(0));

	    options
	        .addSeries(new SimpleSeries()
	            .setName("Tokyo")
	            .setData(
	                Arrays
	                    .asList(new Number[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5,
	                        25.2, 26.5, 23.3, 18.3, 13.9, 9.6 })));

	    options
	        .addSeries(new SimpleSeries()
	            .setName("New York")
	            .setData(
	                Arrays
	                    .asList(new Number[] { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0,
	                        24.8, 24.1, 20.1, 14.1, 8.6, 2.5 })));
		System.out.println(options);
		String optionsStr =  render.toJson(options);
		System.out.println(optionsStr);
		options = render.fromJson(optionsStr, Options.class);
		System.out.println(options);
	}

Hi everybody
I was trying the library and its working perfect, thanks for the nice work.

My use case is as well let customers define a chart by providing the json and i am facing the exact same issue. Even writing to and then reading again the same json is not working as described by silvestrelosada 's last comment.

Do you find any solution yet?
