The use of ico-content inside slide-box


#1

After clicking enabled, slide the next one; the console will report errors"Cannot read property ‘scrollTop’ of null" when sliding again. It will not report errors when I try not inserting ico-content into slide-box, or ico-content setting scroll =“false”. But I need to use pull-to-refresh inside ico-slide. How to solve the problem.
