no re-paint on selection

[#1]

Dear Qlik Sense developers,

I need some advice on the following problem.

I've built an extension, which higlights a certain part of a map when I click on it.

My next step was to filter on the clicked part, and I succeeded, my extension now filters on data when I click on a certain part of my map.

However, when I click on a part, of my map, it now filters data, but then it forces a redraw of the map and the selected part is no longer highlighted.

I want the extension to filter, but I do not want it to redraw and loose the highlighted values.

Is there a way I can force the extension not to redraw, or is there a way I can retrieve my selected value and force the extension to highlight the selected value?

Hope you guys can help.

Well the paint method will be called, but you don't need to actually repaint the contents.You could do something like

paint : function($element, layout) {
    if(this.painted) return;
    this.painted = true;
    //your rendering here, will be called only once
}
