Cannot read property 'marginWidth' of undefined

[lucabenedettini]

Hi,
After I import the library and insert the appopriate tag inside app component html, an error pop up in browser console. The error says "Cannot read property 'marginWidth' of undefined" because the widget's opitons seems to be undefined. How can I instantiate a widget properly?
Thank you for your job.

Same problem here just after the installation

The reported problem :

TestPage.html:19 ERROR TypeError: Cannot read property 'marginWidth' of undefined

caused by:

GridStackItemComponent.prototype.RenderWidget = function (item) { var /** @type {?} */ renderer = this.renderer; if (item != null) this.option = item; this.renderer.setElementAttribute(this.nativeElement, "style", "margin-left:" + this.option.marginWidth + ";");

The example refers to widget1 in the option attribute. This is the one undefined. Replace it or create it and it will fix the problem.

In the second example, [option]="widget.Item" is not correct. It should be [option]="widget"
