$("*:not(:has(*))") causes crash #112

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a gQuery object with the selection $("*:not(:has(*))") 

What is the expected output? What do you see instead?
A valid Gquery object containing all elements which do not have descendents. 
This is what I see instead in Eclipse:

Created HasSelector: com.google.gwt.query.client.impl.SelectorEngineCssToXPath

com.google.gwt.query.client.impl.SelectorEngineNative

:has selector is not implemented yet in gquery, it is not a valid css selector, 
in jquery it is an extension:
http://api.jquery.com/has-selector/

We will implement it in a future release, in the meanwhile use gquery methods 
as a workaround.
$("*").not($("*").has("*")); 

The gquery implementation will delegate on these methods as jquery does, so 
:has cannot take advance of css native selector performance.
