Hello support,

When I'm trying to create an IRayLineChartObject with a specified key using the following statement (according to description in API JavaDoc, Interface IChartObjectFactory):

IRayLineChartObject rayLine = chart.getChartObjectFactory().createRayLine("RayLineTest");

I'm getting a RunTime error:
"java.lang.NoSuchMethodException: com.dukascopy.charts.drawings.RayLineChartObject.<init>(java.lang.String) ..."

How can I create an IRayLineChartObject with a specified key properly ?

I'm using Demo client 2.13.38 with API 2.6.38.1 .

My question was, why the method "IRayLineChartObject IChartObjectFactory.createRayLine(java.lang.String key)", which is described in Interface IChartObjectFactory, is not known at runtime.

I want to use two IRayLines in my strategy. If I use the IChartObjectFactory.createRayLine() construction method without key specification, then I'm not sure if this will cause any problems because theese two ChartObjects are not distinguishable by key.

Also I didn't found a separate method in JavDoc to specify the key of an IChartObject / IRayLineChartObject object after it's creation [like IRayLineChartObject.setKey(java.lang.String key)].

This is a bug which will be fixed with the next release of JForex client. As a consequence, you can't set the key yourself - it gets generated by the platform.
You can get the key by: IChartObject.getKey(). In addition you can always use the object references, as it is done in the following example:
