Execution stuck in Constructor

Hello all, 


I´m trying to port my Custom Visual to the new Developer Plattform. After multiple changes I´m able to compile and start the visual. But now, when I want to put Data into the visual, it just shows nothing. After some debugging I found out, that the Visual seems to be stuck in the constructor method, as the update method is never called. 


The code in the constuctor looks like this 

constructor(options: powerbi.extensibility.visual.VisualConstructorOptions) {
            this.selectionManager =;
            this.options = options;
            // Create main DIV used for the table
            this.root =*.get(0)*/)
                .classed(FormattedColumnsVisual.VisualClassName, true);

the two properties selectionManager and root are defined like this:

private root: D3.Selection;
private selectionManager: ISelectionManager;

So, the visual executes up to the this.root = .... call. Here it seems to be stuck. I don´t get an error Message, but every line of code after this, just doesn´t get executed.


Maybe you have an idea, what could cause this behavior.


Thanks for your help!

You'll need to confirm that there is no error message when you run the visual server by typing pbiviz start in terminal / command line from the root of your visual project. For tips about debugging your custom visual, see the debugging guide.
