问题 I'm working with an accordion that has 10 grids inside of it. So basically I would like to access each grid in the accordian but not really sure how to accomplish that in ExtJS. Example: If I want to target a grid I can do this: Ext.ComponentQuery.query('grid'); But if I use the above code it will target all of the grids from the UI and I don't want that.

问题 I wanted to add a Month and Year picker on my app. So, I found this Fiddle https://fiddle.sencha.com/#fiddle/h5i on one of stackoverflow posts. It uses Extjs 5.0 and works fine. However, if we change it to 4.2.1 the last row on the Month and Year both disappear i.e June, Dec on Months and 2015, 2020 on years disappear. The same can be seen when you choose Extjs 5.0.
