Hi

I am trying to get the line style of ChartObjects. If I have not set the stroke manually, I get a null pointer exception. However, after I set the stroke, my code works fine.

I attach a sample strategy that exhibits the problem.
Simply draw a rectangle; do not change any settings; run the strategy. Gives NullPointerException.
Next, change the stroke; run the strategy. Gives no error.

What am I doing wrong or is this a bug?

Cheers
Tony

Hi JellyBean,

there is a bug in yout code:

private void printDebug(String toPrint) {
        if (printDebug) {
            console.getOut().println( toPrint );
        }
    }

please remove the free space in line: console.getOut().println( toPrint );

private void printDebug(String toPrint) {
        if (printDebug) {
            console.getOut().println(toPrint);
        }
    }

sorry that was not the reason!

it seems that the line style is indeterminate if you never set the stroke.


maybe a bug!?

try this...

  // get active chart
        IChart chart = context.getLastActiveChart();
        
        List<IChartObject> objects = chart.getAll();
        for (IChartObject obj : objects) {
            
            if (obj.getType() == IChart.Type.RECTANGLE) {
                try {
                    obj.getLineStyle();
                } catch (NullPointerException e) {
                    printDebug("unknow linestyle -> set to 0");
                    obj.setLineStyle(0);
                    
                }
                
                printDebug("Rectangle linestyle is " + obj.getLineStyle());
            }
        }

There was a bug that will be fixed with the next demo release.

Thanks Jack.
This works and I'm using it to proceed.
