I seem to be having a problem with recursively updating a list of nodes.
The nodes get created as elements using promises so they complete
rendering themselves.
export class DrawingService {
drawWidget (nodeData, parent) {
return this.componentsFactory.get(nodeData.component, nodeData, parent);
}
drawWidgetAndChildren(node, parentElement) {
this.drawWidget(node, parentElement).then((element) => {
this.drawWidgets(element);
});
}
drawWidgets(parentElement) {
for (var node of this.nodes) {
if (node.parentId == parentElement.attr("id")) {
this.drawWidgetAndChildren(node, parentElement);
}
}
}
}
export function componentsFactory ($compile, $rootScope){
'ngInject';
return {
get: function (component, options, parent) {
return new Promise(
(resolve,reject) => {
let scope = $rootScope.$new();
options.component = component;
options.resolve = resolve;
scope.options = options;
let element = angular.element("<" + component + " options='options' ></" +
component + ">");
element.attr("id", options.id);
let compiledElement = $compile(element)(scope);
parent.append(compiledElement);
});
}
};
The componentsFactory creates a widget element which populates itself with
data and then assigns a resolve => this.options.resolve(this.element);
At the time the widget resolves, its data looks correct. However, when the
drawWidgetAndChildren
then statement returns, the element in the then(element) contains the
original value before it gets populated. Looks like something gets
overwritten in memory.
Would anyone have an idea what i'm doing wrong or is this an angular issue ?
