Unable to use setSelection() in PieCharts when using Java GWT #45

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

We have the following code:
final JsArray<Selection> selectionArray = Selection.createArray().cast();
selectionArray.setLength(1);

final Selection selection = Selection.create(1, null).cast();
selectionArray.set(0, selection);

What is the expected output? What do you see instead?
We keep getting the error:

com.google.gwt.core.client.JavaScriptException: (TypeError) 
@com.googlecode.gwt.charts.client.ChartObject::setSelection(Lcom/google/gwt/core
/client/JsArray;)([JavaScript object(10448)]): Cannot read property 'NaN' of

Any browser.

Class Selection rewritten and tested.
Additionally, created method setSelection(Selection... ) which allow simpler 
selection such as:

chart.setSelection(Selection.create(1, null));

Note: don't forget you can't set a selection unless the chart is ready (see 
ReadyEvent).
