When is the callback updateProperty triggered for a customized widget ?
For a customized widget, sometimes the callback function updateProperty is triggered as my expected, but sometimes not.
I found the following situations that updateProperty will NOT be triggered :
afterRender is empty
Div doesn't has nested div/span inside it . for example, <div class="widget-content widget-helloWorld"><div class="DisplayText"></div></div> works, but <div class="widget-content widget-helloWorld DisplayText"></div> doesn't work
call this.setProperty function in afterRender won't be helpful in the above cases
I'm really confused about the behavior of triggering updateProperty , could someone give me a detailed description for updateProperty ?
