Hi,
Our situation is: We need render several charts into a view. The chart library is not using UI5 tech and it just need a dom node so that it can render the charts into it. Before that we need some Ajax call to get the charts' type.
So we tried some code like: (highly simplified)
getChartsType().done(function(){
view.addContent(new sap.ui.core.HTML({content: '<div id="chartContainer"></div>'}));
myChartLib.renderInto('chartContainer'); // error was thown up, no such element
});
