Watir webdriver and extjs finding element

问题

I am doing an acceptance test using watir-webdriver using ruby I wanna ask if watir webdriver is support for ExtJs or not? I am trying to find element that generated dynamically by ExtJS. I am trying doing some thing like

@browser = Watir::Browser.new :chrome
#Some step go to page
@cbo = @browser.execute_script "return Ext.getCmp('cboCategory')"

but It didn't work Please give me some advises. Thank you.

ExtJS pages are hard to test, especially on finding elements.

Here are some of the tips I consider useful:

Don't ever use dynamically generated IDs. like (:id, 'ext-gen1302')
Don't ever use absolute/meaningless XPath, like //div[4]/div[3]/div[4]/div/div/div/span[2]/span
Take advantage of meaningful auto-generated partial ids and class names.

For example, this ExtJS grid example: (:css, '.x-grid-view .x-grid-table') would be handy. If there are multiple of grids, try index them or locate the identifiable ancestor, like (:css, '#something-meaningful .x-grid-view .x-grid-table').
Create meaningful class names in the source code. ExtJS provides cls and tdCls for custom class names, so you can add cls:'testing-cmb-category' in your source code, and get it by (:css, '.x-panel .testing-cmb-category').
