[zhangleinick]

Hi, all , http://docs.sencha.com/touch/2-1/#!/...avigation_view in this example,I double click on button, it will push twice.How to prevent it?
The same as Ext.dataview.List ,when double click or more on the item, Event of itemtap itemsingletap itemdoubletap, can push twice.
But when I check this: http://dev.sencha.com/deploy/touch/examples/production/navigationview/index.html
It is OK,why?
Please help , I need push only once.Thanks.

You can use singletap or doubletap events but if you double tap then the singletap won't fire.

I usually disable the button while an action is taking place.
